by Daniel Veillard 09 Jan '17

09 Jan '17

Since we had planned a release mid January, it's time to plan the next release, I suggest to shoot for a release next Monday, the 16th. In which case we should enter freeze this Wednesday, then have RC2 on Friday, and then if everything is fine, push the release next Monday. Hope this works for everybody, thanks, Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] RFC for support Intel RDT/CAT in libvirt
by Qiao, Liyong 09 Jan '17

09 Jan '17

Hi folks I would like to start a discussion about how to support a new cpu feature in libvirt. CAT support is not fully merged into linux kernel yet, the target release is 4.10, and all patches has been merged into linux tip branch. So there won’t be interface/design changes. ## Background Intel RDT is a toolkit to do resource Qos for cpu such as llc(l3) cache, memory bandwidth usage, these fine granularity resource control features are very useful in a cloud environment which will run logs of noisy instances. Currently, Libvirt has supported CAT/MBMT/MBML already, they are only for resource usage monitor, propose to supporting CAT to control VM’s l3 cache quota. ## CAT interface in kernel In kernel, a new resource interface has been introduced under /sys/fs/resctrl, it’s used for resource control, for more information, refer Intel_rdt_ui [ https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/tree/Documentation… ] Kernel requires to provide schemata for l3 cache before add a task to a new partition, these interface is too much detail for a virtual machine user, so propose to let Libvirt manage schemata on the host. ## What will libvirt do? ### Questions: To enable CAT support in libvirt, we need to think about follow questions 1. Only set CAT when an VM has CPU pin, which is to say, l3 cache is per cpu socket resources. On a host which has 2 cpu sockets, each cpu socket has it own cache, and can not be shared.. 2. What the cache allocation policy should be used, this will be looks like: a. VM has it’s own dedicated l3 cache and also can share other l3 cache. b. VM can only use the caches which allocated to it. c. Has some pre-defined policies and priority for a VM Like COB [1] 1. Should reserve some l3 cache for host’s system usage (related to 2) 2. What’s the unit for l3 cache allocation? (related to 2) ### Propose Changes XML domain user interface changes: Option 1: explicit specify cache allocation for a VM 1 work with numa node Some cloud orchestration software use numa + vcpu pin together, so we can enable cat supporting with numa infra. Expose how many l3 cache a VM want to reserved and we require that the l3 cache should be bind on some specify cpu socket, just like what we did for numa node. This is an domain xml example which is generated by OpenStack Nova for allocate llc(l3 cache) when booting a new VM <domain> … <cputune> <vcpupin vcpu='0' cpuset='19'/> <vcpupin vcpu='1' cpuset='63'/> <vcpupin vcpu='2' cpuset='83'/> <vcpupin vcpu='3' cpuset='39'/> <vcpupin vcpu='4' cpuset='40'/> <vcpupin vcpu='5' cpuset='84'/> <emulatorpin cpuset='19,39-40,63,83-84'/> </cputune> ... <cpu mode='host-model'> <model fallback='allow'/> <topology sockets='3' cores='1' threads='2'/> <numa> <cell id='0' cpus='0-1' memory='2097152' l3cache='1408' unit='KiB'/> <cell id='1' cpus='2-5' memory='4194304' l3cache='5632' unit='KiB'/> </numa> </cpu> ... </domain> Refer to [http://libvirt.org/formatdomain.html#elementsCPUTuning] So finally we can calculate on which CPU socket(cell) we need to allocate how may l3cache for a VM. 2. work with vcpu pin Forget numa part, CAT setting should have relationship with cpu core setting, we can apply CAT policy if VM has set cpu pin setting (only VM won’t be schedule to another CPU sockets) Cache allocation on which CPU socket can be calculate as just as 1. We may need to enable both 1 and 2. There are several policy for cache allocation: Let’ take some examples: For intel e5 v4 2699(Signal socket), there are 55M l3 cache on the chip , the default of L3 schemata is L3:0=ffffff , it represents to use 20 bit to control l3 cache, each bit will represent 2.75M, which will be the minimal unit on this host. The allocation policy could be 3 policies : 1. One priority VM: A priority import VM can be allocated a dedicated amount l3 cache (let’s say 2.75 * 4 = 11M) and it can also reach the left 44 M cache which will be shared with other process and VM on the same host. So that we need to create a new ‘Partition’ n-20371 root@s2600wt:/sys/fs/resctrl# ls cpus info n-20371 schemata tasks Inside of n-20371 directory: root@s2600wt:/sys/fs/resctrl# ls n-20371/ cpus schemata tasks The schemata content will be L3:0=fffff The tasks content will be the pids of that VM Along we need to change the default schemata of system: root@s2600wt:/sys/fs/resctrl# cat schemata L3:0=ffff # which can not use the highest 4 bits, only tasks in n-20371 can reach that. In this design , we can only get 1 priority VM. Let’s change it a bit to have 2 VMs The schemata of the 2 VMs could be: 1. L3:0=ffff0 # could not use the 4 low bits 11M l3 cache 2. L3:0=0ffff # could not use the 4 high bits 11M l3 cache Default schemata changes to L3:0=0fff0 # default system process could only use the middle 33M l3 cache 2. Isolated l3 cache dedicated allocation for each VM(if required) A VM can only use the cache allocated to it. For example VM 1 requires to allocate 11 M It’s schemata will be L3:0=f0000 # VM 2 requires to allocate 11M It’s schemata will be L3:0=f000 And default schemata will be L3:0=fff In this case, we can create multiple VMs which each of them can have dedicated l3 cache. The disadvantage is that we the allocated cache could be not be shared efficiently. 3. Isolated l3 cache shared allocation for each VM(if required by user) In this case, we will put some VMs (which consider as noisy neighbors) to a ‘Partition’, restrict them to use the only caches allocated to them, by do this, other much more priority VM can be ensure to have enough l3 cache Then we should decide how much cache the noisy group should have, and put all of their pids in that tasks file. Option 2: set cache priority and apply policies Don’t specify cache amount at all, only define cache usage priority when define a VM domain XML. Cache priority will decide how much the VM can use l3 cache on a host, it’s not a quantized. So user don’t need to think about how much cache it should have when define a domain XML. Libvirt will decide cache allocation by the priority of VM defined and policies using. Disadvantage is that caches ability on different host may be different. Same VM domain XML on different host may have vary caches allocation amount. # Support CAT in libvirt itself or leverage other software COB COB is Intel Cache Orchestrator Balancer (COB). please refer http://clrgitlab.intel.com/rdt/cob/tree/master COB supports some pre-defined policies, it will monitor cpu/cache/cache missing and do cache allocation based on policy using. If COB support monitor some specified process (VM process) and accept priority defined, it will be good to reuse. At last the question came out: * Support a fine-grained llc cache control , let user specify cache allocation * Support pre-defined policies and user specify llc allocation priority.

[libvirt] [PATCH 0/6] Don't run whole sec driver in namespace
by Michal Privoznik 09 Jan '17

09 Jan '17

In eadaa97548 I've tried to solve the issue of setting seclabels on private /dev/* entries. While my approach works, it has tiny flaw - anything that happens in the namespace stays in the namespace. I mean, if there's a internal state change occurring on relabel operation (it should not, and it doesn't nowadays, but it's no guarantee), this change is not reflected in the daemon. This is because when entering the namespace, the daemon forks, enters the namespace and then executes the RelabelAll() function. This imperfection is: a) very easy to forget b) very hard to debug Therefore, we may have transaction APIs as suggested here [1]. On transactionBegin() the sec driver will record [path. seclabel] somewhere instead of applying the label. Then on transactionCommit() new process is forked, enters the namespace and perform previously recorded changes. This way it is only the minimal code that runs in the namespace. Moreover, it runs over constant data thus there can be no internal state transition. 1: https://www.redhat.com/archives/libvir-list/2016-December/msg00254.html Michal Privoznik (6): security_selinux: s/virSecuritySELinuxSecurity/virSecuritySELinux/ security_dac: Resolve virSecurityDACSetOwnershipInternal const correctness security driver: Introduce transaction APIs security_dac: Implement transaction APIs security_selinux: Implement transaction APIs qemu: Use transactions from security driver src/libvirt_private.syms | 3 + src/qemu/qemu_driver.c | 28 +++-- src/qemu/qemu_security.c | 98 +++++---------- src/security/security_dac.c | 197 +++++++++++++++++++++++++++++- src/security/security_driver.h | 9 ++ src/security/security_manager.c | 38 ++++++ src/security/security_manager.h | 7 +- src/security/security_selinux.c | 219 +++++++++++++++++++++++++++++++--- src/security/security_stack.c | 49 ++++++++ src/storage/storage_backend.h | 2 +- src/storage/storage_backend_fs.c | 2 +- src/storage/storage_backend_gluster.c | 2 +- src/storage/storage_driver.c | 6 +- src/storage/storage_driver.h | 4 +- src/util/virstoragefile.c | 2 +- src/util/virstoragefile.h | 2 +- 16 files changed, 561 insertions(+), 107 deletions(-) -- 2.11.0

Re: [libvirt] libvirt support for mediated devices
by Laine Stump 09 Jan '17

09 Jan '17

VFIO's new mediated device interface "is used for allowing software-defined devices to be exposed through VFIO while the host driver manages access to the interface" (quoted from http://www.phoronix.com/scan.php?page=news_item&px=VFIO-Linux-4.10-Mediated ). Now that the support for mediated devices has been added to the upstream Linux kernel, there is a stable API that libvirt can use to support assigning mediated devices (e.g. virtual GPUs) to Qemu/KVM guests (or presumably any other hypervisor that support device assignment via VFIO. We've had a few private discussions about what should be added to libvirt, and now have enough rough ideas to start discussing it on the list. The major requirements we've come up with so far (in what I think is a reasonable order of implementation) are: 1) The ability to assign an already-created mediated device to a guest (think of "<hostdev ... managed='no'>" mode for assigning regular PCI devices). 2) reporting of the capabilities of a mediated device "parent" (including, for example, the supported types and maximum number of child devices that are supported, and the names of all existing child devices) and of existing child devices (via the node device APIs, e.g. virsh nodedev-list and virsh nodedev-dumpxml) 3) The ability to create and destroy mediated devices via the NodeDevice API. (similar in function to the "virsh detach-device and virsh attach-device commands - i.e. they make a device ready to be assigned to a guest using <hostdev>, but have no persistent config and no "auto-start" capability). 4) Support for "managed" mediated devices - libvirt will create a new child device as required, and destroy it when it's no longer needed (similar to the way that standard PCI hostdevs are (when managed="yes") detached from their host driver and attached to vfio-pci as needed) (I think this is less useful than item (5), but is simpler and may be a good way to test all the preceding additions (as well as being useful in some simpler configurations). 5) The ability to create and manage "pools" of mediated devices, with persistent config and an auto-start capability so that the device pools are automatically created when the host is booted (this will require either some form of persistent config and lifecycle management to be added to the nodedevice driver, or a new libvirt driver type with functionality similar to storage pools, but used to manage pools of mdev child devices). ========= Going back to the beginning, with slightly more detail: 1) "Unmanaged" mediated device assignment - assigning an existing device to a virtual machine This will assume that the desired child device has already been created, and can be found in /sys/bus/mdev/devices/$UUID. Here's a first attempt at what the XML would look like: <hostdev mode='subsystem' type='pci' /managed='no'>/ <source>  <mdev uuid='$uuid'/> </source> <address type='pci' blah blah blah/>  </hostdev> In the past, the "type" attribute of hostdev described the type on both the host and the guest. With mediated devices, the device isn't visible on the host as a PCI device, but just as a software device. So the type attribute in <hostdev> now gives the type of the device on the guest, and the device type on the host is determined from the contents of <source>. Erik had a different suggestion for this (which I think he's already working on patches for) - that the type attribute in <hostdev> should be the type of the device in the *host*, and the type in the guest would be that given in the <address>. Something like this I think: <hostdev mode='subsystem' type='mdev' /managed='no'/> <source> <mdev uuid='$uuid'/> </source> <address type='pci' blah blah blah/> </hostdev> (Is this correct, Erik?) (I arrived at my suggestion by the thinking that, in other places where there are similar attributes for the host and guest side, e.g. the IP addresses and routes that can be added on both the host and guest side of an <interface>, everything related to the host side is in the <source> subelement, while things related to the guest are directly under the toplevel of the device element. On the other hand, the "managed" attribute isn't something related to the guest, but to the host, and his idea has less redundancy, so maybe he's onto something...) (NB: a mediated device could be exposed to the guest as a PCI device, a CCW device, or anything else supported by vfio. The type of device that the guest will see can be determined from the contents of mdev_supported_types/<type-id>/device_api under the parent device's directory in sysfs (it will be, e.g., "vfio-pci" or "vfio-ccw"). But libvirt assigns guest-side addresses at the time a domain is defined, and it's possible that the mdev child device won't be created yet at define time (and therefore we won't know which parent device it's associated with, and so we won't be able to look at device_api). In such situations, it will be up to management to know something about the device it will be creating and assume a type. Fortunately this is a reasonably safe thing to do - on x86 platforms we can be fairly certain that the device will be a PCI device. (And, because this also makes a difference for some machinetypes, that it will be a PCI Express device). We will want to check device_api at runtime though, to validate that the guest-side device really is a PCI device. == 2) Reporting parent and child mediated devices and their capabilities in the node device API. There are 3 stages to this: a) add mediated child devices to the list of devices provided by "virsh nodedev-list". These will be called "mdev_$UUID", and will show up as descendents of their respective parent devices in "virsh nodedev-list --tree". The list of all these devices can easily be retrieved by enumerating the links in /sys/bus/mdev/devices/$UUID. b) report the capabilities of parent devices in their dumpxml output. This will included supported child device types and a list of current children. I don't have any experience with nodedev reporting for SCSI devices, but recently noticed that nodedev-list can report lists of devices with certain capabilities, e.g. "virsh nodedev-list --cap=scsi_host". Based on this, I guess it would be useful for the parent devices to show something like this (using the sample mtty driver as an example): <device> <name>pci_0000_02_00_0</name> <parent>pci_0000_00_04_0</parent> <driver> <name>mtty</name> </driver> <capability type='mdev_parent'> [list of supported types, each with number allowed] [list of current child devices (just giving uuid or device name ("mdev_$uuid"?)] [other info about parent/children?] </capability> ... Likewise, a nodedev-dumpxml of a child device should contain a pointer to the parent device. c) respond to dumpxml requests for mediated child devices. This should include at least the uuid/type of the child device, and a link back to the parent device (and I suppose somehow include <capability type='mdev_child'> so that it can be filtered with virsh modedev-list?) == (3), (4), and (5) need more thought that I haven't gotten to yet. TBD (if anyone else has thoughts on those, please share!)

[libvirt] memory-ballooning side-channel attack
by bancfc＠openmailbox.org 08 Jan '17

08 Jan '17

Hello and Happy Holidays, In the past few years many serious attacks against the memory deduplication (KSM) feature of all hypervisors have been shown. [1] Even allowing attackers to modify/steal APT keys and source lists on the host. [2] Since its not enabled by default the fall out is relatively low and easily mitigated. New side-channel attacks against memory-ballon enabled VMs are beginning to surface. Please consider documenting this and disabling this feature for newly created VMs to have safe defaults. [1] https://staff.aist.go.jp/c.artho/papers/EuroSec2011-suzaki.pdf [2] https://www.usenix.org/system/files/conference/usenixsecurity16/sec16_paper… [3] http://ieeexplore.ieee.org/document/7562068/ *Hint: If you can't see the IEEE paper use sci-hub.

[libvirt] [PATCH v2 0/2] Allow migration with invtsc if TSC frequency is explicitly set
by Eduardo Habkost 08 Jan '17

08 Jan '17

This series makes QEMU accept migration if tsc-frequency is explicitly set on configuration. As management software is required to keep device configuration the same on migration source or destination, explicit tsc-frequency will ensure that either: * The destination host has a matching TSC frequency; or * The destination host has TSC scaling available. Changes series v1 -> v2 ======================= * v1 series subject was: * [PATCH 0/4] Allow migration with invtsc if there's no frequency mismatch * Removed patches 3/4 and 4/4, that allowed migration if no explicit tsc-frequency was set. Implementing the check on post_load or post_init is not enough to make migration abort, so we will need a more complex solution to implement that feature. Plans for future work ===================== 1) Querying host TSC frequency/scaling capability ------------------------------------------------- I plan to include TSC frequency/scaling information on query-cpu-model-expansion model="host" in a future series. Then management software will be able to automatically configure TSC frequency when invtsc is enabled, instead of requiring the user to configure it explicitly. While we don't implement that, invtsc migration will be possible only if the user configures TSC frequency manually. 2) invtsc migration with no explicit TSC frequency -------------------------------------------------- A future series can implement migration when TSC frequency is not specified explicitly. It will be a bit more complex because it requires either letting the destination abort the migration, or sending TSC frequency/scaling information from destination to source. --- Cc: Marcelo Tosatti <mtosatti(a)redhat.com> Cc: "Daniel P.

[libvirt] Regarding Migration Code
by Anubhav Guleria 08 Jan '17

08 Jan '17

Greetings, I was trying to understand the flow of Migration Code in libvirt and have few doubts: 1) libvirt talks to QEMU/KVM guests via QEMU API. So overall, in order to manage QEMU/KVM guests I can either use libvirt (or tools based on libvirt like virsh) or QEMU monitor. Is it so? 2) Since libvirt is Hypervisor neutral so actual migration algorithm(precopy or postcopy) is present in the hypervisor ,i.e. in case of QEMU it should be present in QEMU code base . I was going through the code starting from libvirt-domain api and not able to follow after virDomainMigrateVersion3Full(.....) . Kindly help. 3) I want to determine the Migration Time, Downtime and other resource usage. What is the correct way to determine the same? Should I use libvirt API or directly virsh or something else? Which is fast and efficient way for the same? Thanks in advance. And sorry if that was too basic

[libvirt] [PATCH v2 0/4] Allow creation of vHBA by parent_wwnn/wwpn or fabric_name
by John Ferlan 06 Jan '17

06 Jan '17

v1: http://www.redhat.com/archives/libvir-list/2016-November/msg00866.html Based on ACKs some of the v1 changes were pushed to make this series appear shorter. Changes since v1 - Patch 1 (formerly patch 4) Rather than separate XML elements, use the existing <parent> and just make attributes for wwnn, wwpn, and fabric_wwn. The parent element can now be string text or empty. Added checked for if either wwnn/wwpn provided, then the other is too. - Patch 2 (formerly patch 5) No changes, but no formal ACK either - Patch 3 (formerly patch 10) Rather than READ_WWN macro across two functions, I created a helper function to read and compare the various wwn values (wwnn, wwpn, and fabric_wwn). John Ferlan (4): nodedev: Add the ability to create vHBA by parent wwnn/wwpn or fabric_wwn conf: Add more fchost search fields for storage pool vHBA creation util: Introduce virGetFCHostNameByFabricWWN iscsi: Add parent wwnn/wwpn or fabric capability for createVport docs/schemas/basictypes.rng | 15 ++++ docs/schemas/nodedev.rng | 24 +++++- src/conf/node_device_conf.c | 126 +++++++++++++++++++++++++++++++ src/conf/node_device_conf.h | 14 ++++ src/conf/storage_conf.c | 21 +++++- src/conf/storage_conf.h | 3 + src/libvirt_private.syms | 3 + src/node_device/node_device_driver.c | 13 ++++ src/storage/storage_backend_scsi.c | 21 +++++- src/util/virutil.c | 141 ++++++++++++++++++++++++++--------- src/util/virutil.h | 4 + 11 files changed, 346 insertions(+), 39 deletions(-) -- 2.7.4

[libvirt] [PATCH v2] libxl: define a per-domain logger.
by Cédric Bosdonnat 06 Jan '17

06 Jan '17

libxl doesn't provide a way to write one log for each domain. Thus we need to demux the messages. If our logger doesn't know to which domain to attribute a message, then it will write it to the default log file. Starting with Xen 4.9 (commit f9858025 and following), libxl will write the domain ID in an easy to grab manner. The logger introduced by this commit will use it to demux the libxl log messages. Thanks to the default log file, this logger will also work with older versions of Xen. --- * v2: addressed Jim's comments src/Makefile.am | 1 + src/libxl/libxl_conf.c | 38 +------- src/libxl/libxl_conf.h | 4 +- src/libxl/libxl_domain.c | 4 + src/libxl/libxl_driver.c | 2 + src/libxl/libxl_logger.c | 223 +++++++++++++++++++++++++++++++++++++++++++++++ src/libxl/libxl_logger.h | 39 +++++++++ 7 files changed, 274 insertions(+), 37 deletions(-) create mode 100644 src/libxl/libxl_logger.c create mode 100644 src/libxl/libxl_logger.h diff --git a/src/Makefile.am b/src/Makefile.am index b71378728..e34d52345 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -851,6 +851,7 @@ LIBXL_DRIVER_SOURCES = \ libxl/libxl_capabilities.c libxl/libxl_capabilities.h \ libxl/libxl_domain.c libxl/libxl_domain.h \ libxl/libxl_driver.c libxl/libxl_driver.h \ + libxl/libxl_logger.c libxl/libxl_logger.h \ libxl/libxl_migration.c libxl/libxl_migration.h UML_DRIVER_SOURCES = \ diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index b569ddad8..ac83b51c7 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -76,9 +76,7 @@ libxlDriverConfigDispose(void *obj) virObjectUnref(cfg->caps); libxl_ctx_free(cfg->ctx); - xtl_logger_destroy(cfg->logger); - if (cfg->logger_file) - VIR_FORCE_FCLOSE(cfg->logger_file); + libxlLoggerFree(cfg->logger); VIR_FREE(cfg->configDir); VIR_FREE(cfg->autostartDir); @@ -1356,8 +1354,6 @@ libxlDriverConfigPtr libxlDriverConfigNew(void) { libxlDriverConfigPtr cfg; - char *log_file = NULL; - xentoollog_level log_level = XTL_DEBUG; char ebuf[1024]; unsigned int free_mem; @@ -1386,9 +1382,6 @@ libxlDriverConfigNew(void) if (VIR_STRDUP(cfg->channelDir, LIBXL_CHANNEL_DIR) < 0) goto error; - if (virAsprintf(&log_file, "%s/libxl-driver.log", cfg->logDir) < 0) - goto error; - if (virFileMakePath(cfg->logDir) < 0) { virReportError(VIR_ERR_INTERNAL_ERROR, _("failed to create log dir '%s': %s"), @@ -1397,37 +1390,13 @@ libxlDriverConfigNew(void) goto error; } - if ((cfg->logger_file = fopen(log_file, "a")) == NULL) { - VIR_ERROR(_("Failed to create log file '%s': %s"), - log_file, virStrerror(errno, ebuf, sizeof(ebuf))); - goto error; - } - VIR_FREE(log_file); - - switch (virLogGetDefaultPriority()) { - case VIR_LOG_DEBUG: - log_level = XTL_DEBUG; - break; - case VIR_LOG_INFO: - log_level = XTL_INFO; - break; - case VIR_LOG_WARN: - log_level = XTL_WARN; - break; - case VIR_LOG_ERROR: - log_level = XTL_ERROR; - break; - } - - cfg->logger = - (xentoollog_logger *)xtl_createlogger_stdiostream(cfg->logger_file, - log_level, XTL_STDIOSTREAM_SHOW_DATE); + cfg->logger = libxlLoggerNew(cfg->logDir, virLogGetDefaultPriority()); if (!cfg->logger) { VIR_ERROR(_("cannot create logger for libxenlight, disabling driver")); goto error; } - if (libxl_ctx_alloc(&cfg->ctx, LIBXL_VERSION, 0, cfg->logger)) { + if (libxl_ctx_alloc(&cfg->ctx, LIBXL_VERSION, 0, (xentoollog_logger *)cfg->logger)) { VIR_ERROR(_("cannot initialize libxenlight context, probably not " "running in a Xen Dom0, disabling driver")); goto error; @@ -1478,7 +1447,6 @@ libxlDriverConfigNew(void) return cfg; error: - VIR_FREE(log_file); virObjectUnref(cfg); return NULL; } diff --git a/src/libxl/libxl_conf.h b/src/libxl/libxl_conf.h index 851f3afb4..69d78851a 100644 --- a/src/libxl/libxl_conf.h +++ b/src/libxl/libxl_conf.h @@ -41,6 +41,7 @@ # include "locking/lock_manager.h" # include "virfirmware.h" # include "libxl_capabilities.h" +# include "libxl_logger.h" # define LIBXL_DRIVER_NAME "xenlight" # define LIBXL_VNC_PORT_MIN 5900 @@ -74,8 +75,7 @@ struct _libxlDriverConfig { unsigned int version; /* log stream for driver-wide libxl ctx */ - FILE *logger_file; - xentoollog_logger *logger; + libxlLoggerPtr logger; /* libxl ctx for driver wide ops; getVersion, getNodeInfo, ... */ libxl_ctx *ctx; diff --git a/src/libxl/libxl_domain.c b/src/libxl/libxl_domain.c index 5cde576ef..3bc468f61 100644 --- a/src/libxl/libxl_domain.c +++ b/src/libxl/libxl_domain.c @@ -809,6 +809,8 @@ libxlDomainCleanup(libxlDriverPrivatePtr driver, VIR_FREE(xml); } + libxlLoggerCloseFile(cfg->logger, vm->def->id); + virDomainObjRemoveTransientDef(vm); virObjectUnref(cfg); } @@ -1291,6 +1293,8 @@ libxlDomainStart(libxlDriverPrivatePtr driver, */ vm->def->id = domid; + libxlLoggerOpenFile(cfg->logger, domid, vm->def->name); + /* Always enable domain death events */ if (libxl_evenable_domain_death(cfg->ctx, vm->def->id, 0, &priv->deathW)) goto destroy_dom; diff --git a/src/libxl/libxl_driver.c b/src/libxl/libxl_driver.c index 7e5d9b69e..6a4ecddef 100644 --- a/src/libxl/libxl_driver.c +++ b/src/libxl/libxl_driver.c @@ -406,6 +406,8 @@ libxlReconnectDomain(virDomainObjPtr vm, /* Update domid in case it changed (e.g. reboot) while we were gone?

[libvirt] [PATCH 0/9] More event handling support
by Daniel P. Berrange 06 Jan '17

06 Jan '17

This series adds suppoort for more events - Event when <metadata> in a domain changes - Event when virSecret are created/deleted - Event when virSecret value is changed The latter two of course required wiring up the secret object for event support, since we've not had secret events before now.

Berrange (9): Add domain event for metadata changes Introduce secret lifecycle event APIs conf: add secret event handling conf: simplify internal virSecretDef handling of usage remote: implement secret lifecycle event APIs secret: add support for lifecycle events examples: add secret events to event demo program virsh: add secret lifecycle event handling secret: add support for value change events daemon/libvirtd.h | 2 + daemon/remote.c | 276 ++++++++++++++++++++++++++++++++ examples/object-events/event-test.c | 107 +++++++++++++ include/libvirt/libvirt-domain.h | 20 +++ include/libvirt/libvirt-secret.h | 92 +++++++++++ src/Makefile.am | 5 + src/access/viraccessdriverpolkit.c | 8 +- src/bhyve/bhyve_driver.c | 7 + src/conf/domain_event.c | 86 ++++++++++ src/conf/domain_event.h | 10 ++ src/conf/secret_conf.c | 74 ++------- src/conf/secret_conf.h | 9 +- src/conf/secret_event.c | 311 ++++++++++++++++++++++++++++++++++++ src/conf/secret_event.h | 65 ++++++++ src/conf/virsecretobj.c | 42 +---- src/datatypes.c | 3 +- src/datatypes.h | 14 ++ src/driver-secret.h | 14 ++ src/libvirt-secret.c | 129 +++++++++++++++ src/libvirt_private.syms | 9 +- src/libvirt_public.syms | 2 + src/lxc/lxc_driver.c | 6 + src/qemu/qemu_driver.c | 6 + src/remote/remote_driver.c | 196 ++++++++++++++++++++++- src/remote/remote_protocol.x | 69 +++++++- src/remote_protocol-structs | 26 +++ src/secret/secret_driver.c | 82 +++++++++- src/storage/storage_backend.c | 2 +- src/test/test_driver.c | 6 + tools/virsh-domain.c | 25 +++ tools/virsh-secret.c | 225 ++++++++++++++++++++++++++ tools/virsh.pod | 18 +++ 32 files changed, 1829 insertions(+), 117 deletions(-) create mode 100644 src/conf/secret_event.c create mode 100644 src/conf/secret_event.h -- 2.9.3

[libvirt] [PATCH 0/9] Qemu: s390: Cpu Model Support
by Jason J. Herne 06 Jan '17

06 Jan '17

This patch set enables cpu model support for s390. The user can now set exact cpu models, query supported models via virsh domcapabilities, and use host-model and host-passthrough modes. The end result is that migration is safer because Qemu will perform runnability checking on the destination host and quit with an error if the guest's cpu model is not supported. Note: Some test data has been separated from corresponding test case updates for ease of review. Changelog --------- [v3] s390: Cpu driver support for update and compare - Fixed indentation of error message in virCPUs390Update test-data: Qemu caps replies and xml for s390x qemu 2.7 and 2.8 - Moved this patch before introduction of query-cpu-model-expansion - Regenerated all test data tests: domain capabilities: qemu 2.7 and 2.8 on s390x - Added Qemu 2.7 test - Removed fake host model name - Moved this patch before introduction of query-cpu-model-expansion tests: qemu capabilites: qemu 2.7 and 2.8 on s390x - Moved this patch before introduction of query-cpu-model-expansion - Stop using fake host cpu qemu: qmp query-cpu-model-expansion command - Moved query-cpu-model-expansion capability to this patch - changed label "cleanup" to "error" in qemuMonitorCPUModelInfoCopy - qemuMonitorJSONParseCPUModelProperty is now static, and also made appropriate changes when passing a boolean to virJSONValueGetBoolean - removed unnecessary error checking when assigning "data" variable in qemuMonitorJSONGetCPUModelExpansion - Fix up capabilities test data to reflect changes from this commit - fixed query-cpu-model-expansion's enumeration formatting qemu-caps: Get host model directly from Qemu when available - Moved query-cpu-model-expansion capability from this patch - virQEMUCapsCopyCPUModelFromQEMU is now static and type void - check for native guest is done before attempting to set host CPU - s390x no longer falls back to getting host CPU model from the host if it cannot be retrieved from QEMU - fixed unnecessary intialization of some variables that were introduced in v2 of these patches - virQEMUCapsLoadHostCPUModelInfo now first allocates data into a qemuMonitorCPUModelInfoPtr before assigning it to appropriate qemuCaps field - if we do not have QEMU_CAPS_QUERY_CPU_MODEL_EXPANSION available, skip trying to read the hostCPU portion of the qemu cache file - all hostCPU element parsing is handled in its entirety within function virQEMUCapsLoadHostCPUModelInfo - Fix up capabilities test data to reflect changes from this commit qemu: command: Support new cpu feature argument syntax - Add error message for case where s390 guest attempts to use cpu features on older qemu. - Combined the tests into this commit - Now tests s390 cpu features both with and without query-cpu-model-expansion [v2] * Added s390x cpu and capabilities tests * Added cpu feature syntax tests * Dropped patch: Warn when migrating host-passthrough * Added patch: Document migrating host-passthrough is dangerous s390: Cpu driver support for update and compare - Compare: Added comment explaining why s390 bypasses the cpuCompare operation - Update: Added error message explaining minimum match mode is not supported - Update: Ensure user is not using unsupported optional feature policy - Update: Use virCPUDefUpdateFeature to update/create user requested features - Other minor fixes s390-cpu: Remove nodeData and decode - Completely remove nodeData and decode functions qemu: qmp query-cpu-model-expansion command - Cleaned up debug print - Restructured qemuMonitorJSONGetCPUModelExpansion - Added more JSON parsing error handling - CPU model features now parsed via an iterator - qemuMonitorJSONGetCPUModelExpansion: Fixed double free of model ptr - Restructure qemuMonitorCPUModelInfoFree - Other minor fixes qemu-caps: Get host model directly from Qemu when available - virQEMUCapsProbeQMPHostCPU: indentation fix - Fixed rebase error involving a missing 'goto cleanup;'. - Fix indentation in virQEMUCapsProbeQMPHostCPU - virQEMUCapsInitHostCPUModel now routes to virQEMUCapsCopyModelFromQEMU or virQEMUCapsCopyModelFromHost, depending on architecture. - Restructure hostCpu data in qemu caps cache xml - Other minor fixes Collin L.

Let me introduce more about MCDRAM, MCDRAM is on-package high-bandwidth memory (~500GB/s). On KNL platform, hardware expose MCDRAM as a seperate, CPUless and remote NUMA node to OS so that MCDRAM will not be allocated by default (since MCDRAM node has no CPU, every CPU regards MCDRAM node as remote node). In this way, MCDRAM can be reserved for certain specific applications. > > Different from the traditional X86 server, There is a special numa > > node with Multi-Channel DRAM (MCDRAM) on Phi, but without any CPU . > > > > Now libvirt requires nonempty cpus argument for NUMA node, such as. > > <numa> > > <cell id='0' cpus='0-239' memory='80' unit='GiB'/> > > <cell id='1' cpus='240-243' memory='16' unit='GiB'/> </numa> > > > > In order to support phi virtualization, libvirt needs to allow a numa > > cell definition without 'cpu' attribution. > > > > Such as: > > <numa> > > <cell id='0' cpus='0-239' memory='80' unit='GiB'/> > > <cell id='1' memory='16' unit='GiB'/> </numa> > > > > When a cell without 'cpu', qemu will allocate memory by default MCDRAM instead of DDR. > > There's separate concepts at play which your description here is mixing up. > > First is the question of whether the guest NUMA node can be created with only RAM or CPUs, or a mix of both. > > Second is the question of what kind of host RAM (MCDRAM vs DDR) is used as the backing store for the guest > Guest NUMA node shoulde be created with memory only (keep the same as host's) and the more important things is the memory should bind to (come from) host MCDRAM node. > These are separate configuration items which don't need to be conflated in libvirt. ie we should be able to create a guest with a node containing only memory, and back that by DDR on the host.

However, some filesystems mounted under /dev needs to be preserved in order to be shared with the parent namespace (e.g. /dev/pts). Currently, the list of mount points to preserve is hardcoded which ain't right - on some systems there might be less or more items under real /dev that on our list. The solution is to parse /proc/mounts and fetch the list from there.

[libvirt] [libivrt] storage: Two iSCSI node records may cause refreshing iscsi pool failed
by Shichangkuo 05 Jan '17

05 Jan '17

Hi, John When starting an iscsi storage pool, libvirt will execute “iscsiadm --mode node --portal 192.168.0.42 --targetname iqn.2003-10.com.xxxx --op new”, which is called by virISCSINodeNew. This will add an iSCSI node record. The record file is /etc/iscsi/nodes/iqn.2003-10.com.xxxx/192.168.0.42,3260. When we already executed "iscsiadm --mode discovery --type sendtargets --portal 192.168.0.42 --op new", another iSCSI node record will be produced in /etc/iscsi/nodes/iqn.2003-10.com.xxxx/192.168.0.42,3260,1/default. Then two iscsi sessions, as [2] and [3], will be logged in when we start the pool. Device of session [2] is /dev/sde, and device of session [3] is /dev/sdf. But there is only one path in /dev/disk/by-path, let's assume it is /dev/sdf. Refreshing storage pool will choose first session, like [2], and libvirt will find sde NOT sdf in /dev/disk/by-path. We will not find sde, then no volumes is found in the pool. I think the root reason is we have two iSCSI node records. Can we use "iscsiadm --mode discovery --type sendtargets --portal 192.168.0.42 --op new" in virISCSINodeNew? diff --git a/src/util/viriscsi.c b/src/util/viriscsi.c index 504ffbd..a8a8644 100644 --- a/src/util/viriscsi.c +++ b/src/util/viriscsi.c @@ -469,9 +469,9 @@ virISCSINodeNew(const char *portal, int ret = -1; cmd = virCommandNewArgList(ISCSIADM, - "--mode", "node", + "--mode", "discovery", + "--type", "sendtargets", "--portal", portal, - "--targetname", target, "--op", "new", NULL); Thanks, Changkuo. ------------------------------------------------------------------------------------------------------------------------------------- 本邮件及其附件含有杭州华三通信技术有限公司的保密信息，仅限于发送给上面地址中列出的个人或群组。禁止任何其他人以任何形式使用（包括但不限于全部或部分地泄露、复制、或散发）本邮件中的信息。如果您错收了本邮件，请您立即电话或邮件通知发件人并删除本邮件！ This e-mail and its attachments contain confidential information from H3C, which is intended only for the person or entity whose address is listed above.

[libvirt] [PATCH] internal: Simplify STREQ_NULLABLE
by Michal Privoznik 05 Jan '17

05 Jan '17

Our STREQ_NULLABLE and STRNEQ_NULLABLE macros are too complicated. This was a result of some broken version of gcc. However, that is long gone and therefore we can simplify the macros.

[libvirt] [PATCH 0/3] Improve release notes process

The release note process we have had in place since v2.5.0 was never meant to be anything more than a stop-gap measure until a better solution was devised.

[libvirt] Loosing lxc guests when restarting libvirt
by Christian Ehrhardt 05 Jan '17

05 Jan '17

Hi, I found an issue in libvirt related to libvirt-lxc, but fail to find the root cause. The TL;DR is: libvirt-lxc guests get killed on libvirt restart due to "internal error: No valid cgroup for machine" It was able to reproduce libvirt 1.3.1, 2.4 and 2.5 as packages in Ubuntu and Debian. I wanted to ask for two things: - wider coverage where this does reproduce - your expertise on the case itself. Steps to reproduce: 1. Spawn new KVM Guest of your choice 2. install test dependencies $ apt-get install libvirt-daemon-system libvirt-clients libxml2-utils # or package managers / package names of your chosen os 3. run the following sequence as root export LIBVIRT_DEFAULT_URI=lxc:/// cat << EOF > /tmp/smoke-lxc.xml <domain type='lxc'> <name>sl</name> <memory unit='KiB'>256000</memory> <currentMemory unit='KiB'>256000</currentMemory> <vcpu placement='static'>1</vcpu> <os> <type>exe</type> <init>/bin/bash</init> </os> <features> <privnet/> </features> <clock offset='utc'/> <devices> <emulator>/usr/lib/libvirt/libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='/'/> <target dir='/'/> </filesystem> <console type='pty'> <target type='lxc' port='0'/> </console> </devices> </domain> EOF virsh define /tmp/smoke-lxc.xml virsh start sl virsh list --all # is running now /etc/init.d/libvirtd restart virsh list --all # is no more running, but it should Way more background and detail can be found at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=848317 -- Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd

If we restart libvirtd while VM was doing external memory snapshot, VM's state be updated to paused as a result of running a migration-to-file operation, and then VM will be left as paused state.

[libvirt] GSoC 2017
by Michal Privoznik 05 Jan '17

Hey, so we are approaching opening date for submitting orgnaization applications [1]. In order to have perfect application we need to show Google a list of ideas that students can work on (like they couldn't google it up, right? ;-)). You can find the list here [2]. Let me ask you kindly to go through it and: a) add whatever idea you feel is appropriate, b) if you have an idea but don't feel like mentoring, leave the 'Mentor' field empty and I will find somebody. There is still plenty of time left (I'll probably fill out the application form at the end of the month), but please don't leave it until the last hour. There were some changes to the program discussed on the Mentor Summit, but I don't see anything announced yet, so stay tuned. As for our organization, historically we had 1:N mapping of mentors and students (one mentor could have had one or more students). But last year we tried out 2:1 mapping and I found it better so probably we will stick to co-mentoring this year too (as everything, it's recommended not required). Happy new year!

[libvirt] [PATCH] docs: fix list of domain states in virsh manpage
by Laine Stump 04 Jan '17

04 Jan '17

The virsh manpage lists "shutdown" and "dying" as two of the possible domain states that could be listed in the output of the "virsh list" command. However, a domain that is being shutdown will be listed as "in shutdown", and the "dying" state doesn't even exist (and never has, as far as I can tell from looking through git history - it was shown in the original import of the virsh.pod file in 2006; there was no VIR_DOMAIN_DYING state then, there wasn't one when those lines of virsh.pod were tweaked in 2008, and there still isn't one today.

[libvirt] [PATCH] libxl: define a per-domain logger.
by Cédric Bosdonnat 04 Jan '17

04 Jan '17

libxl doesn't provide a way to write one log for each domain. Thus we need to demux the messages. If our logger doesn't know to which domain to attribute a message, then it will write it to the default log file. Starting with Xen 4.9 (commit f9858025 and following), libxl will write the domain ID in an easy to grab manner. The logger introduced by this commit will use it to demux the libxl log messages. Thanks to the default log file, this logger will also work with older versions of Xen. --- src/Makefile.am | 1 + src/libxl/libxl_conf.c | 38 +-------- src/libxl/libxl_conf.h | 4 +- src/libxl/libxl_domain.c | 4 + src/libxl/libxl_driver.c | 2 + src/libxl/libxl_logger.c | 217 +++++++++++++++++++++++++++++++++++++++++++++++ src/libxl/libxl_logger.h | 39 +++++++++ 7 files changed, 268 insertions(+), 37 deletions(-) create mode 100644 src/libxl/libxl_logger.c create mode 100644 src/libxl/libxl_logger.h diff --git a/src/Makefile.am b/src/Makefile.am index b71378728..e34d52345 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -851,6 +851,7 @@ LIBXL_DRIVER_SOURCES = \ libxl/libxl_capabilities.c libxl/libxl_capabilities.h \ libxl/libxl_domain.c libxl/libxl_domain.h \ libxl/libxl_driver.c libxl/libxl_driver.h \ + libxl/libxl_logger.c libxl/libxl_logger.h \ libxl/libxl_migration.c libxl/libxl_migration.h UML_DRIVER_SOURCES = \ diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index b569ddad8..929179903 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -76,9 +76,7 @@ libxlDriverConfigDispose(void *obj) virObjectUnref(cfg->caps); libxl_ctx_free(cfg->ctx); - xtl_logger_destroy(cfg->logger); - if (cfg->logger_file) - VIR_FORCE_FCLOSE(cfg->logger_file); + libxlLoggerFree(cfg->logger); VIR_FREE(cfg->configDir); VIR_FREE(cfg->autostartDir); @@ -1356,8 +1354,6 @@ libxlDriverConfigPtr libxlDriverConfigNew(void) { libxlDriverConfigPtr cfg; - char *log_file = NULL; - xentoollog_level log_level = XTL_DEBUG; char ebuf[1024]; unsigned int free_mem; @@ -1386,9 +1382,6 @@ libxlDriverConfigNew(void) if (VIR_STRDUP(cfg->channelDir, LIBXL_CHANNEL_DIR) < 0) goto error; - if (virAsprintf(&log_file, "%s/libxl-driver.log", cfg->logDir) < 0) - goto error; - if (virFileMakePath(cfg->logDir) < 0) { virReportError(VIR_ERR_INTERNAL_ERROR, _("failed to create log dir '%s': %s"), @@ -1397,37 +1390,13 @@ libxlDriverConfigNew(void) goto error; } - if ((cfg->logger_file = fopen(log_file, "a")) == NULL) { - VIR_ERROR(_("Failed to create log file '%s': %s"), - log_file, virStrerror(errno, ebuf, sizeof(ebuf))); - goto error; - } - VIR_FREE(log_file); - - switch (virLogGetDefaultPriority()) { - case VIR_LOG_DEBUG: - log_level = XTL_DEBUG; - break; - case VIR_LOG_INFO: - log_level = XTL_INFO; - break; - case VIR_LOG_WARN: - log_level = XTL_WARN; - break; - case VIR_LOG_ERROR: - log_level = XTL_ERROR; - break; - } - - cfg->logger = - (xentoollog_logger *)xtl_createlogger_stdiostream(cfg->logger_file, - log_level, XTL_STDIOSTREAM_SHOW_DATE); + cfg->logger = libxlLoggerNew(cfg->logDir, virLogGetDefaultPriority()); if (!cfg->logger) { VIR_ERROR(_("cannot create logger for libxenlight, disabling driver")); goto error; } - if (libxl_ctx_alloc(&cfg->ctx, LIBXL_VERSION, 0, cfg->logger)) { + if (libxl_ctx_alloc(&cfg->ctx, LIBXL_VERSION, 0, (void*)cfg->logger)) { VIR_ERROR(_("cannot initialize libxenlight context, probably not " "running in a Xen Dom0, disabling driver")); goto error; @@ -1478,7 +1447,6 @@ libxlDriverConfigNew(void) return cfg; error: - VIR_FREE(log_file); virObjectUnref(cfg); return NULL; } diff --git a/src/libxl/libxl_conf.h b/src/libxl/libxl_conf.h index 851f3afb4..69d78851a 100644 --- a/src/libxl/libxl_conf.h +++ b/src/libxl/libxl_conf.h @@ -41,6 +41,7 @@ # include "locking/lock_manager.h" # include "virfirmware.h" # include "libxl_capabilities.h" +# include "libxl_logger.h" # define LIBXL_DRIVER_NAME "xenlight" # define LIBXL_VNC_PORT_MIN 5900 @@ -74,8 +75,7 @@ struct _libxlDriverConfig { unsigned int version; /* log stream for driver-wide libxl ctx */ - FILE *logger_file; - xentoollog_logger *logger; + libxlLoggerPtr logger; /* libxl ctx for driver wide ops; getVersion, getNodeInfo, ... */ libxl_ctx *ctx; diff --git a/src/libxl/libxl_domain.c b/src/libxl/libxl_domain.c index 5cde576ef..3bc468f61 100644 --- a/src/libxl/libxl_domain.c +++ b/src/libxl/libxl_domain.c @@ -809,6 +809,8 @@ libxlDomainCleanup(libxlDriverPrivatePtr driver, VIR_FREE(xml); } + libxlLoggerCloseFile(cfg->logger, vm->def->id); + virDomainObjRemoveTransientDef(vm); virObjectUnref(cfg); } @@ -1291,6 +1293,8 @@ libxlDomainStart(libxlDriverPrivatePtr driver, */ vm->def->id = domid; + libxlLoggerOpenFile(cfg->logger, domid, vm->def->name); + /* Always enable domain death events */ if (libxl_evenable_domain_death(cfg->ctx, vm->def->id, 0, &priv->deathW)) goto destroy_dom; diff --git a/src/libxl/libxl_driver.c b/src/libxl/libxl_driver.c index 7e5d9b69e..6a4ecddef 100644 --- a/src/libxl/libxl_driver.c +++ b/src/libxl/libxl_driver.c @@ -406,6 +406,8 @@ libxlReconnectDomain(virDomainObjPtr vm, /* Update domid in case it changed (e.g. reboot) while we were gone?

[libvirt] [PATCH 00/11] Allow creation of vHBA by parent_wwnn/wwpn or fabric_name
by John Ferlan 04 Jan '17

04 Jan '17

https://bugzilla.redhat.com/show_bug.cgi?id=1349696 Lots of details in the bz, but essentially the problem is that providing a "parent" scsi_hostX value has drawbacks on reboots because what was scsi_hostX could turn into scsi_hostY on subsequent reboots. So add the ability to use the parent wwnn/wwpn or fabric_wwn as 'search' criteria in order to create either non persistent vHBA's via nodedev or persistent vHBA's via storage pools. NB: Documentation of this "process" is on the wiki: http://wiki.libvirt.org/page/NPIV_in_libvirt and would need to be adjusted once/if the changes are accepted. John Ferlan (11): nodedev: Fix crash in libvirtd on vHBA creation path nodedev: Create helpers to search for vport capable nodedevs nodedev: Add ability to find a vport capable vHBA nodedev: Add the ability to create vHBA by parent wwnn/wwpn or fabric_wwn conf: Add more fchost search fields for storage pool vHBA creation iscsi: Clean up createVport exit paths iscsi: Change order of checks in createVport iscsi: Converge more createVport checks util: Remove need for extra VIR_FREE's in virGetFCHostNameByWWN util: Introduce virGetFCHostNameByFabricWWN iscsi: Add parent wwnn/wwpn or fabric capability for createVport docs/schemas/basictypes.rng | 15 +++ docs/schemas/nodedev.rng | 15 +++ src/conf/node_device_conf.c | 234 +++++++++++++++++++++++++++++++---- src/conf/node_device_conf.h | 17 +++ src/conf/storage_conf.c | 21 +++- src/conf/storage_conf.h | 3 + src/libvirt_private.syms | 4 + src/node_device/node_device_driver.c | 28 ++++- src/storage/storage_backend_scsi.c | 86 +++++++------ src/util/virutil.c | 113 ++++++++++++----- src/util/virutil.h | 4 + 11 files changed, 439 insertions(+), 101 deletions(-) -- 2.7.4

[libvirt] [PATCH] qemu: Don't assume secret provided for LUKS encryption
by John Ferlan 03 Jan '17

03 Jan '17

https://bugzilla.redhat.com/show_bug.cgi?id=1405269 If a secret was not provided for what was determined to be a LUKS encrypted disk (during virStorageFileGetMetadata processing when called from qemuDomainDetermineDiskChain as a result of hotplug attach qemuDomainAttachDeviceDiskLive), then do not attempt to look it up (avoiding a libvirtd crash) and do not alter the format to "luks" when adding the disk; otherwise, the device_add would fail with a message such as: "unable to execute QEMU command 'device_add': Property 'scsi-hd.drive' can't find value 'drive-scsi0-0-0-0'" because of assumptions that when the format=luks that libvirt would have provided the secret to decrypt the volume. Access to unlock the volume will thus be left to the application. Signed-off-by: John Ferlan <jferlan(a)redhat.com> --- I could have spread things over 2 patches (one to create the helper and one to add the extra check for nsecrets > 0), but just going with one to fix the issue just felt cleaner (besides makes any possible backports a bit simpler).

I was notified about a virmacmaptest crash that happens on FreeBSD. Interestingly, the problem occurs on Linux too, but for some reason the process is not getting SIGSEGV.

[libvirt] Libvirtd is not started as a service
by Weiwei Jia 31 Dec '16

31 Dec '16

Hi Daniel, I download libvirt 2.5.0 source codes and install them as following steps. $ ./autogen.sh --prefix=/usr --localstatedir=/var --sysconfdir=/etc $ make $ sudo make install However, the libvirtd is not started as a service daemon. $ initctl stop libvirt-bin initctl: Unknown job: libvirt-bin Is libvirtd started as a service daemon by default after 'make install'? Or I need to start it manually. Is there any doc to make libvirtd as a service daemon, which is located at '/etc/init.d/libvirtd' for debian? My distro version is > lsb_release -a No LSB modules are available. Distributor ID: LinuxMint Description: Linux Mint 17.2 Rafaela Release: 17.2 Codename: rafaela The same as Ubuntu 14.04 Trusty. Thanks, Weiwei Jia

[libvirt] [PATCH] network: write both lo and lo0 in dnsmasq configuration
by Pino Toscano 28 Dec '16

28 Dec '16

When generating a new configuration for dnsmasq, add except-interface for both lo and lo0: this should make sure the configuration works, and is always the same for every supported OS. Adjust the data of networkxml2conftest to reflect the new dnsmasq configuration, making networkxml2conftest pass on non-Linux OSes.

[libvirt] Cannot add iothreads label in libvirt xml configuration file
by Weiwei Jia 24 Dec '16

24 Dec '16

Hi, I cannot add iothreads (https://libvirt.org/formatdomain.html#elementsIOThreadsAllocation) in the libvirt xml configuration file. Once I add "<iothreads>4</iothreads>" and other related config for IOthreads into the libvirt xml configuration file with virsh command and save it, these iothreads related configuration will disappear after I open libvirt xml configuration file again for double-check. The current libvirt xml configuration file is like following. # virsh dumpxml kvm1 <domain type='kvm'> <name>kvm1</name> <uuid>20811918-9057-4496-aa03-0fe9d1bcaf78</uuid> <memory

[libvirt] [PATCH v3 00/11] clean up after slot sharing patches
by Laine Stump 23 Dec '16

23 Dec '16

(rebase of the original patches to make review easier) Some of the patches that enabled sharing PCI slots by multiple pcie-root-ports made the idea of reserving an entire slot obsolete. To reduce confusion and misunderstandings, this patch series gets rid of the name "Slot" in all of the functions that reserve and release PCI addresses. Laine Stump (11): conf: fix fromConfig argument to virDomainPCIAddressReserveAddr() conf: fix fromConfig argument to virDomainPCIAddressValidate() conf: rename virDomainPCIAddressGetNextSlot() to ...GetNextAddr() conf: eliminate virDomainPCIAddressReserveNextSlot() qemu: replace virDomainPCIAddressReserveAddr with virDomainPCIAddressReserveSlot conf: make virDomainPCIAddressReserveAddr() a static function conf: rename virDomainPCIAddressReserveAddr() to ...Internal() conf: rename virDomainPCIAddressReserveSlot() to ...Addr() qemu: remove qemuDomainPCIAddressReserveNextAddr() qemu: rename qemuDomainPCIAddressReserveNextSlot() to ...Addr() conf: eliminate virDomainPCIAddressReleaseSlot() in favor of ...Addr() src/bhyve/bhyve_device.c | 26 ++++++---- src/conf/domain_addr.c | 60 +++++------------------ src/conf/domain_addr.h | 15 ------ src/libvirt_private.syms | 4 +- src/qemu/qemu_domain_address.c | 105 ++++++++++++++++++++--------------------- 5 files changed, 80 insertions(+), 130 deletions(-) -- 2.7.4

[libvirt] [PATCH] tests/networkxml2conf: Fix to work again on non-Linux
by Andrea Bolognani 23 Dec '16

23 Dec '16

Since commit 478ddedc12b7 the name of the loopback interface in the generated dnsmasq configuration is OS-dependent. However, the test suite has not been updated to cope with the change, causing it to fail on FreeBSD and other non-Linux operating systems. Modify the networkxml2conf test case to read the expected output from different files based on the OS we're building on. --- .../{dhcp6-nat-network.conf => dhcp6-nat-network-linux.conf} | 0

[libvirt] [PATCH] domain_conf: set ifname for ovs vhostuser ifname
by Mehdi Abaakouk 22 Dec '16

22 Dec '16

Hi, This is the followup of '[PATCH v3 4/4] domain_conf: autodetect vhostuser ifname'. I have rewritten a better version that shouldn't have the same concern as before. I have isolated the code that detects the ifname in util/virnetdevopenvswitch.c in a new helper function virNetDevOpenvswitchGetVhostuserIfname(). Unlike the previous version, it returns a ifname only if the vhostuser interface is handled by openswitch. So, if the vhostuser is not handled by openvswitch, the ifname stay NULL. Now, virDomainNetDefParseXML() only calls this function, it does nothing else now.

[libvirt] [PATCH] m4/virt-gnutls: use AC_CHECK_FUNCS to detect availability of functions
by Pavel Hrdina 22 Dec '16

22 Dec '16

Sigh, autoconf has AC_CHECK_FUNC and AC_CHECK_FUNCS and both check whether some function exists or not. However in addition to the obvious difference that the later is able to check multiple functions it also defines HAVE_FUNCTION_NAME for each function. Commit 680d2f49da moved the code to separate file, but also blindly changed the macro to AC_CHECK_FUNC without confronting the documentation.

[libvirt] [PATCH RFC v3 00/15] FSPool: backend directory
by Olga Krishtal 21 Dec '16

21 Dec '16

Hi everyone, we would like to propose the first implementation of fspool with directory backend according to previous discussions: https://www.redhat.com/archives/libvir-list/2016-April/msg01941.html https://www.redhat.com/archives/libvir-list/2016-May/msg00208.html https://www.redhat.com/archives/libvir-list/2016-September/msg00463.html Filesystem pools is a facility to manage filesystems resources similar to how storage pools manages volume resources.The manageble unit is a single filesystem, so fspool items have only one type - dir (storage pools can manage files, block devices, etc). However, backends for fspools can be different. This series introduses the simplest backend - host directory. API mostly follows storage pool API: we can create fspool, build it, populate with items. Moreover, to create filesystem pool we need some storage. So, all structures to describe storage that will hold fspool is borrowed from storage pool ones. The same is true for functions that work with them. As it was mentioned before - here we present directory backend for fspool. To mangae fspools and items we tried to use as much functionality from storage pool (directory and fs backend) as possible. The first 3 patches - is preparational refactoring. Both storage pool and fspool reside upon some storage, so there is a good chance to use the same code for describing storage source and functions that work with it. All reusable code is moved virpoolcommon.c/.h It would be great if you share you thoughts about such changes. Because what we trying to achive - is to have less copy/paste and to have separate drivers for storage pools and filesystem pools. All other patches is devoted to fspool implementation and is presented according libvirt recommendations. Uploading/downloading operations are not defined yet as it is not obvious how to make it properly. I guess we can use some kind of tar to make a stream from a filesystem. Please share you thoughts on this particular issue. v2: - renamed Fs to FS - in configure.ac script macro m4 is used - updates docs - created simple tests - updated virsh.pod - added information abot fspool in fotmatfs.html v3: - in this version storage pool code is reused - resplitted patches - fixed some errors Olga Krishtal (15): storage pools: refactoring of basic structs storage pools: functions refactoring storage pools: refactoring of fs backend FSPool: defining the public API FSPool: defining the internal API FSpool: implementing the public API FSPool: added access control objects and permissions FSPool: added --with-fs compilation option FSPool: implementation of remote protocol FSPool: added configuration description virsh: filesystem pools commands FSPool: empty implementation of driver methods FSPool: driver methods implementation FSPool: directory backend inplementation FSPool: Tests and documentation configure.ac | 6 + daemon/Makefile.am | 4 + daemon/libvirtd.c | 9 + daemon/remote.c | 35 + docs/formatfs.html.in | 206 ++ docs/fspool.html.in | 41 + docs/schemas/fsitem.rng | 66 + docs/schemas/fspool.rng | 82 + docs/sitemap.html.in | 4 + include/libvirt/libvirt-fs.h | 254 +++ include/libvirt/libvirt-storage.h | 5 +- include/libvirt/libvirt.h | 1 + include/libvirt/virterror.h | 7 + m4/virt-driver-fspool.m4 | 43 + po/POTFILES.in | 7 + src/Makefile.am | 59 +- src/access/viraccessdriver.h | 15 + src/access/viraccessdrivernop.c | 21 + src/access/viraccessdriverpolkit.c | 47 + src/access/viraccessdriverstack.c | 50 + src/access/viraccessmanager.c | 32 + src/access/viraccessmanager.h | 11 +- src/access/viraccessperm.c | 15 +- src/access/viraccessperm.h | 126 ++ src/check-driverimpls.pl | 2 + src/conf/fs_conf.c | 1479 ++++++++++++++ src/conf/fs_conf.h | 262 +++ src/conf/storage_conf.c | 162 -- src/conf/storage_conf.h | 137 +- src/datatypes.c | 150 ++ src/datatypes.h | 60 +- src/driver-fs.h | 193 ++ src/driver.h | 3 + src/fs/fs_backend.h | 94 + src/fs/fs_backend_dir.c | 290 +++ src/fs/fs_backend_dir.h | 8 + src/fs/fs_driver.c | 2044 ++++++++++++++++++++ src/fs/fs_driver.h | 10 + src/libvirt-fs.c | 1555 +++++++++++++++ src/libvirt.c | 30 +- src/libvirt_private.syms | 58 +- src/libvirt_public.syms | 46 + src/remote/remote_driver.c | 66 + src/remote/remote_protocol.x | 466 ++++- src/remote_protocol-structs | 165 ++ src/rpc/gendispatch.pl | 23 +- src/storage/storage_backend.h | 1 - src/storage/storage_backend_fs.c | 74 +- src/util/virerror.c | 37 + src/util/virpoolcommon.c | 212 ++ src/util/virpoolcommon.h | 189 ++ src/util/virstoragefile.c | 73 + src/util/virstoragefile.h | 3 + tests/Makefile.am | 12 + tests/fsitemxml2xmlin/item.xml | 13 + tests/fsitemxml2xmlout/item.xml | 13 + tests/fsitemxml2xmltest.c | 105 + .../dir-missing-target-path-invalid.xml | 12 + tests/fspoolxml2xmlin/fspool-dir.xml | 16 + tests/fspoolxml2xmlout/fspool-dir.xml | 16 + tests/fspoolxml2xmltest.c | 81 + tools/Makefile.am | 2 + tools/virsh-fsitem.c | 1293 +++++++++++++ tools/virsh-fsitem.h | 39 + tools/virsh-fspool.c | 1574 +++++++++++++++ tools/virsh-fspool.h | 38 + tools/virsh.c | 4 + tools/virsh.h | 9 + tools/virsh.pod | 252 ++- 69 files changed, 12128 insertions(+), 389 deletions(-) create mode 100644 docs/formatfs.html.in create mode 100644 docs/fspool.html.in create mode 100644 docs/schemas/fsitem.rng create mode 100644 docs/schemas/fspool.rng create mode 100644 include/libvirt/libvirt-fs.h create mode 100644 m4/virt-driver-fspool.m4 create mode 100644 src/conf/fs_conf.c create mode 100644 src/conf/fs_conf.h create mode 100644 src/driver-fs.h create mode 100644 src/fs/fs_backend.h create mode 100644 src/fs/fs_backend_dir.c create mode 100644 src/fs/fs_backend_dir.h create mode 100644 src/fs/fs_driver.c create mode 100644 src/fs/fs_driver.h create mode 100644 src/libvirt-fs.c create mode 100644 src/util/virpoolcommon.c create mode 100644 src/util/virpoolcommon.h create mode 100644 tests/fsitemxml2xmlin/item.xml create mode 100644 tests/fsitemxml2xmlout/item.xml create mode 100644 tests/fsitemxml2xmltest.c create mode 100644 tests/fspoolschemadata/dir-missing-target-path-invalid.xml create mode 100644 tests/fspoolxml2xmlin/fspool-dir.xml create mode 100644 tests/fspoolxml2xmlout/fspool-dir.xml create mode 100644 tests/fspoolxml2xmltest.c create mode 100644 tools/virsh-fsitem.c create mode 100644 tools/virsh-fsitem.h create mode 100644 tools/virsh-fspool.c create mode 100644 tools/virsh-fspool.h -- 1.8.3.1

[libvirt] [PATCH 0/2] qemu: migration: show disks stats for nbd migration
by Nikolay Shirokovskiy 21 Dec '16

21 Dec '16

Current migration stats will show something like [1] when in the process of mirroring of non shared disks. This gives very little info on the migration progress. Likewise completed stats miss disks mirroring info. This patch provides disks stats in the said phase like in [2] so user can now understand what's going on. However data stats miss memory stats, so data total and remaining will change when memory migration starts. AFAIU disks stats were available before the nbd based migration becomes the default. So this patch returns disks stats back at some level. Patch 1 is just a little cleanup. Removed code uses qemuMigrationFetchJobStatus so the patch 1 helps analysis of the patch 2.

[libvirt] connecting to qemu domain monitor socket outside of libvirt/virsh
by Jason Miesionczek 21 Dec '16

21 Dec '16

Hi, So I see that when i have a qemu vm running, that i created via libvirt, there is a socket here: /var/lib/libvirt/qemu/domain-<name>/monitor.sock I am trying to connect to this socket via cli or a completely separate C/C++ application to be able to control the VM, but I can't seem to get it to work. Does anyone know if/how this is possible? I've tried 'nc', 'socat', and based on the qemu libvirt code, 'socket'/'connect', but nothing seems to work. Also, is it possible through libvirt, when creating a qemu VM, one can specify to enable the QMP socket? Thanks in advance, Jason

[libvirt] [RFC] add option to bring new qemu binary/pending conf changes on reboot
by Nikolay Shirokovskiy 21 Dec '16

21 Dec '16

Hi, all. I'm trying to reword the long pending RFC [1]. We interested in next usecase. Administrator update qemu binary/make domain configuration changes that transparent to the guest. This changes are not applied until domain shutdown/started by domain user. Sometimes user just reboots domain and these changes as they transparent can be applied too and this is a good opportunity to apply changes. For example new qemu binary have some optimizations and administrator would like to use these optimizations and don't want to force user to restart, waiting for user reboot is considered good enough. To support this use case we can add 'recreate' option to on_reboot/on_shutdown event. [1] https://www.redhat.com/archives/libvir-list/2016-June/msg02259.html

[libvirt] New libvirt maven releasing and issue with detach volume
by Rohit Yadav 21 Dec '16

21 Dec '16

Hi, >From [1][2] I found the emails on your ML and owner of libvirt-java. I see several changes since last libvirt-java release 0.5.1, can we have a release please if those changes are critical for libvirt users? I've found and reported an issue with detach volume/disk that fails to remove the xml/vbd from the VM's xml, I'm not sure if it's related to the libvirt 0.5.1 library (that we used for testing): http://markmail.org/thread/djzxozewjfhsyimh Any help or comment on this would be great. Thanks. [1] http://libvirt.org/git/?p=libvirt-java.git;a=summary [2] https://libvirt.org/contact.html#email Regards.

Hi all, With the new website, it still has the News page: https://libvirt.org/news.html But there doesn't seem to be a link to it from anywhere. Is that a bug? + Justin

One of the regexes has a bogus \o instead of plain 'o'. Somehow this magically worked on all versions of python, until 3.6 came along and complained Signed-off-by: Daniel P.

But I worry that by defining a complete set of static models on x86 would require extra maintenance work on the QEMU side with no visible benefit for libvirt.

[libvirt] [PATCH 0/3] Get the voldef target physical value
by John Ferlan 20 Dec '16

20 Dec '16

This effort started primarily to address some ideas/thoughts brought up in https://bugzilla.redhat.com/show_bug.cgi?id=1332019 although as things were updated, it seems that using storage volume definitions wouldn't be necessary since the same data can be obtained via the virDomainGetBlockInfo API. Still since code had been written - I figured I'd posted it and see what kind of feedback it got. The first patch just adds the <physical> element to the output XML and documents it thusly. The 2nd/3rd patch take a different approach adding virStorageVolInfoFlags which could take a single flag indicating that the caller would prefer to return the "physical" value instead of the "allocation" value. Yes, kind of a hack, but since we cannot extend _virStorageVolInfo to add a physical it's a mechanism to allow fetching the data using existing structures. Sure a virStorageVolStats API could be created as well, but I figured I'd see how this went first before thinking about that.
