[libvirt] [PATCH] libxl: use xenlight pkgconfig file if present
by Jim Fehlig 19 Mar '15

19 Mar '15

xen.git commit babeca32 added a pkgconfig file for libxenlight, allowing libxl apps to determine the location of Xen binaries such as firmware blobs, device emulator, etc. This patch adds support for xenlight.pc in the libxl driver, falling back to the previous configure logic if not found. It introduces LIBXL_FIRMWARE_DIR and LIBXL_EXECBIN_DIR to define the firmware and libexec_bin locations. If xenlight.pc does not exist, the defines are set to the current hardcoded paths. The capabilities' <emulator> and <loader> elements are updated to use the paths.

[libvirt] [PATCH 0/2] target-i386: Haswell-noTSX and Broadwell-noTSX CPU models
by Eduardo Habkost 19 Mar '15

19 Mar '15

With the Intel microcode update that removed HLE and RTM, there will be different kinds of Haswell and Broadwell CPUs out there: some that still have the HLE and RTM features, and some that don't have the HLE and RTM features. On both cases people may be willing to use the pc-*-2.3 machine-types. So instead of making the CPU model results confusing by making it depend on the machine-type, keep HLE and RTM on the existing Haswell and Broadwell CPU models, and introduce "Haswell-noTSX" and "Broadwell-noTSX" CPU models later, for people who have CPUs that don't have TSX feature available. Eduardo Habkost (2): Revert "target-i386: Disable HLE and RTM on Haswell & Broadwell" target-i386: Haswell-noTSX and Broadwell-noTSX hw/i386/pc_piix.c | 4 --- hw/i386/pc_q35.c | 4 --- target-i386/cpu.c | 74 +++++++++++++++++++++++++++++++++++++++++++++++++++++-- 3 files changed, 72 insertions(+), 10 deletions(-) -- 2.1.0

[libvirt] [PATCH] parallels: fix libvirt crash if parallelsNetworkClose fails
by Maxim Nestratov 19 Mar '15

19 Mar '15

If, by any reason, parallelsNetworkClose fails it dereferences newly allocated privconn->networks via virObjectUnref, which in turn deallocates its memory. Subsequent call of parallelsNetworkClose calls virObjectUnref that leads to double memory free. To prevent this we should zero privconn->networks to make all subsequent virObjectUnref be safe.

[libvirt] [PATCH v2 0/6] parallels: implement managed save
by Dmitry Guryanov 19 Mar '15

This patch series is intended to implement all needed code, so that suspend/resume in openstack nova will work. It implements .domainHasManagedSaveImage, .domainManagedSave and .domainManagedSaveRemove functions. Also it adds workaround to parallelsDomainDefineXMLFlags to skip applying configuration, if VM is in managed save state and config hasn't been changed, because it's not possible to change VM config in suspended state in PCS. Changes in v2: * rebased Dmitry Guryanov (6): parallels: fix headers in parallels_sdk.h parallels: split prlsdkDomainChangeState function parallels: implement virDomainManagedSave parallels: report, that cdroms are readonly parallels: add controllers in prlsdkLoadDomain parallels: fix virDomainDefineXML for domain in saved state src/parallels/parallels_driver.c | 101 +++++++++++++++++++++++++++++++++++++-- src/parallels/parallels_sdk.c | 65 ++++++++++++++++++------- src/parallels/parallels_sdk.h | 17 +++++-- 3 files changed, 157 insertions(+), 26 deletions(-) -- 2.1.0

[libvirt] USB hostdev de/reattaching
by Martin Polednik 19 Mar '15

19 Mar '15

Hello, according to libvirt documentation, when using hostdev with USB device "...the user is responsible to call virNodeDeviceDettach (or virsh nodedev-detach) before starting the guest...". In libvirt-1.2.13-1.el7.x86_64, this leads to virsh nodedev-detach usb_usb1 error: Failed to detach device usb_usb1 error: invalid argument: device usb_usb1 is not a PCI device The failure is most probably caused in qemuNodeDeviceDeta where qemuNodeDeviceGetPCIInfo is called. Is it a bug, or usb hostdev can be done without detaching/reattaching? Thanks, mpolednik

[libvirt] [PATCH] libxl: Don't overwrite errors from xenconfig
by Jim Fehlig 19 Mar '15

19 Mar '15

When converting domXML from native, the libxl driver was overwriting useful errors from the xenconfig parsing code with a useless, generic error. E.g. "internal error: parsing xm config failed" vs "internal error: config value usbdevice was malformed". Remove the redundant (and useless) error reporting in the libxl driver.

[libvirt] [PATCH v3 4/4] migration: Expose 'cancelling' status to user
by zhanghailiang 18 Mar '15

18 Mar '15

'cancelling' status is introduced by commit 51cf4c1a, which is mainly avoid possible starting a new migration process while the previous one still exist. But we don't expose this status to user, instead by return a 'active' state. Here, we expose it to the user (such as libvirt), 'cancelling' status only occurs for a short window before the migration aborts, so for users, if they cancell a migration process, it will observe 'cancelling' status occasionally.

[libvirt] [PATCH] util: more verbose error when failing to create macvtap device

Investigation of a problem with creating passthrough macvtap devices (https://bugzilla.redhat.com/show_bug.cgi?id=1185501) has shown that this slightly more verbose failure message is useful.

Issue #1 - A call to virBitmapNew did not check if the allocation failed which could lead to a NULL dereference Issue #2 - When deleting the pin entries from the config file, the code loops from the number of elements down to the "new" vcpu count; however, the pin id values are numbered 0..n-1 not 1..n, so the "first" pin attempt would never work.

[libvirt] [PATCH] libvirt: move default nwfilters to datadir.
by Dimitri John Ledkov 18 Mar '15

18 Mar '15

libvirt runs correctly without any configuration files, as sensible defaults are used throughout. This commit introduces a layer for nwfilter configuration. This means that default filters are shipped in /usr/share/libvirt/nwfilter/ directory, which can be overridden by things in /etc/libvirt/nwfilter. This is similar to configuration splits as observed in udev, systemd, XDG Base Directory Specification and so on. This will make a distinction and make it obvious if any of the nwfilters are modified by the administrator. --- examples/xml/nwfilter/Makefile.am | 2 +- src/conf/nwfilter_conf.h | 1 + src/nwfilter/nwfilter_driver.c | 18 +++++++++++------- 3 files changed, 13 insertions(+), 8 deletions(-) diff --git a/examples/xml/nwfilter/Makefile.am b/examples/xml/nwfilter/Makefile.am index ec1e7ee..61f328a 100644 --- a/examples/xml/nwfilter/Makefile.am +++ b/examples/xml/nwfilter/Makefile.am @@ -37,7 +37,7 @@ EXTRA_DIST=$(FILTERS) confdir = $(sysconfdir)/libvirt -NWFILTER_DIR = "$(DESTDIR)$(sysconfdir)/libvirt/nwfilter" +NWFILTER_DIR = "$(DESTDIR)$(datadir)/libvirt/nwfilter" if WITH_NWFILTER install-data-local: diff --git a/src/conf/nwfilter_conf.h b/src/conf/nwfilter_conf.h index 6e68ecc..ee427b1 100644 --- a/src/conf/nwfilter_conf.h +++ b/src/conf/nwfilter_conf.h @@ -577,6 +577,7 @@ struct _virNWFilterDriverState { virNWFilterObjList nwfilters; char *configDir; + char *defaultsDir; bool watchingFirewallD; }; diff --git a/src/nwfilter/nwfilter_driver.c b/src/nwfilter/nwfilter_driver.c index 8e3db43..2e81dbf 100644 --- a/src/nwfilter/nwfilter_driver.c +++ b/src/nwfilter/nwfilter_driver.c @@ -173,7 +173,6 @@ nwfilterStateInitialize(bool privileged, virStateInhibitCallback callback ATTRIBUTE_UNUSED, void *opaque ATTRIBUTE_UNUSED) { - char *base = NULL; DBusConnection *sysbus = NULL; if (!privileged) @@ -228,17 +227,20 @@ nwfilterStateInitialize(bool privileged, goto error; } - if (VIR_STRDUP(base, SYSCONFDIR "/libvirt") < 0) + if (virAsprintf(&driver->configDir, + SYSCONFDIR "/libvirt/nwfilter") == -1) goto error; - if (virAsprintf(&driver->configDir, - "%s/nwfilter", base) == -1) + if (virNWFilterLoadAllConfigs(&driver->nwfilters, + driver->configDir) < 0) goto error; - VIR_FREE(base); + if (virAsprintf(&driver->defaultsDir, + PKGDATADIR "/nwfilter") == -1) + goto error; if (virNWFilterLoadAllConfigs(&driver->nwfilters, - driver->configDir) < 0) + driver->defaultsDir) < 0) goto error; nwfilterDriverUnlock(); @@ -246,7 +248,6 @@ nwfilterStateInitialize(bool privileged, return 0; error: - VIR_FREE(base); nwfilterDriverUnlock(); nwfilterStateCleanup(); @@ -292,6 +293,8 @@ nwfilterStateReload(void) virNWFilterLoadAllConfigs(&driver->nwfilters, driver->configDir); + virNWFilterLoadAllConfigs(&driver->nwfilters, + driver->defaultsDir); virNWFilterCallbackDriversUnlock(); virNWFilterUnlockFilterUpdates(); @@ -345,6 +348,7 @@ nwfilterStateCleanup(void) virNWFilterObjListFree(&driver->nwfilters); VIR_FREE(driver->configDir); + VIR_FREE(driver->defaultsDir); nwfilterDriverUnlock(); } -- 2.1.0

[libvirt] [PATCH] Use PAUSED state for domains that are starting up
by Jiri Denemark 18 Mar '15

18 Mar '15

When libvirt is starting a domain, it reports the state as SHUTOFF until it's RUNNING. This is not ideal because domain startup may take a long time (usually because of some configuration issues, firewalls blocking access to network disks, etc.) and domain lists provided by libvirt look awkward. One can see weird shutoff domains with IDs in a list of active domains or even shutoff transient domains. In any case, it looks more like a bug in libvirt than a normal state a domain goes through.

[libvirt] Enhancing block/disk migration in libvirt
by Tony Breeds 18 Mar '15

18 Mar '15

Hello all, I'm new to both openstack and libvirt so I may get some of this slightly wrong[1]. Here is some context form the openstack world (which at least some of you are aware of). There are at least 2 open bug against openstack (nova) in the area of block/disk migration. 1) Live migration fails when the instance has a config-drive[2] Here openstack(nova) fails because a drive that nova expects to be migrated isn't migrated. 2) libvirt live_snapshot periodically explodes on libvirt 1.2.2 in the gate[3] Here openstack(nova) fails because a drive that nova expects NOT to be migrated is migrated. To me these are essentially the same bug/issue. There is no way to communicate with libvirt the users expectations around block/disk mirgration. My idea so far would be to add an options element to the 'disk' XML node. This element could start with 3 possible states block_migration="default": Let libvirt decide block_migration="yes": This device should be block migrated block_migration="no": This device should *NOT* be block migrated The absence of this element would be treated as "default" above. This would mean that all existing domain XML would still be valid and have the expected behaviour and users (such as opensatck) can be explicit about deviced that do/do not need to be block migrated. While I'm certainly open to discussing the finer points of the implementation, right now I'm interested in getting a feel for is this idea generally ok? Yours Tony. [1] I'm happy to be corrected / pointed at community guidelines that I may have missed. [2] https://bugs.launchpad.net/nova/+bug/1246201 [3] https://bugs.launchpad.net/nova/+bug/1334398

[libvirt] [PATCH] util: clean up #includes of virnetdevopenvswitch.h
by Laine Stump 17 Mar '15

17 Mar '15

[libvirt] [PATCH v3] qemu: read backing chain names from qemu
by Eric Blake 17 Mar '15

17 Mar '15

https://bugzilla.redhat.com/show_bug.cgi?id=1199182 documents that after a series of disk snapshots into existing destination images, followed by active commits of the top image, it is possible for qemu 2.2 and earlier to end up tracking a different name for the image than what it would have had when opening the chain afresh. That is, when starting with the chain 'a <- b <- c', the name associated with 'b' is how it was spelled in the metadata of 'c', but when starting with 'a', taking two snapshots into 'a <- b <- c', then committing 'c' back into 'b', the name associated with 'b' is now the name used when taking the first snapshot. Sadly, older qemu doesn't know how to treat different spellings of the same filename as identical files (it uses strcmp() instead of checking for the same inode), which means libvirt's attempt to commit an image using solely the names learned from qcow2 metadata fails with a cryptic: error: internal error: unable to execute QEMU command 'block-commit': Top image file /tmp/images/c/../b/b not found even though the file exists. Trying to teach libvirt the rules on which name qemu will expect is not worth the effort (besides, we'd have to remember it across libvirtd restarts, and track whether a file was opened via metadata or via snapshot creation for a given qemu process); it is easier to just always directly ask qemu what string it expects to see in the first place. As a safety valve, we validate that any name returned by qemu still maps to the same local file as we have tracked it, so that a compromised qemu cannot accidentally cause us to act on an incorrect file. * src/qemu/qemu_monitor.h (qemuMonitorDiskNameLookup): New prototype. * src/qemu/qemu_monitor_json.h (qemuMonitorJSONDiskNameLookup): Likewise. * src/qemu/qemu_monitor.c (qemuMonitorDiskNameLookup): New function. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONDiskNameLookup) (qemuMonitorJSONDiskNameLookupOne): Likewise. * src/qemu/qemu_driver.c (qemuDomainBlockCommit) (qemuDomainBlockJobImpl): Use it.

[libvirt] [PATCH] Add support for Midonet virtual ports
by Antoni Segura Puimedon 17 Mar '15

17 Mar '15

Up until now, to plug VMs into the Midonet virtual networks it was necessary to use the 'last resort' 'ethernet' type. That implied having the domain tainted and having to deal witht the tap lifecycle outside of libvirt/VM lifecycle. With the patch I submit, a new virtualport type will be accepted by libvirt that will always require an interfaceid (as it is essential for binding a tap device to a virtual port that the virtual port itself exists and has a UUID). With that interfaceid, libvirt will delegate the binding on the Midonet userspace tools.

[libvirt] [PULL 13/13] migration: Expose 'cancelling' status to user
by Juan Quintela 17 Mar '15

17 Mar '15

From: zhanghailiang <zhang.zhanghailiang(a)huawei.com> 'cancelling' status was introduced by commit 51cf4c1a, mainly to avoid a possible start of a new migration process while the previous one still exists. But we didn't expose this status to user, instead we returned the 'active' state. Here, we expose it to the user (such as libvirt), 'cancelling' status only occurs for a short window before the migration aborts, so for users, if they cancel a migration process, it will observe 'cancelling' status occasionally. Testing revealed that with older libvirt (anything 1.2.13 or less) will print an odd error message if the state is seen, but that the migration is still properly cancelled. Newer libvirt will be patched to recognize the new state without the odd error message.

[libvirt] [PATCH v2] rpm-build: use pkg-config to detect wireshark presence
by Pavel Hrdina 17 Mar '15

17 Mar '15

Wireshark supports pkg-config since 1.11.3. Right now we build wireshark-dissectior tool as default trough rpm build only on fedora >= 21 and there is new wireshark that supports pkg-config. If someone wants to build libvirt with wireshark-dissector against old wireshark, they should specify the location by hand. This patch is mainly to fix wrong dependency on wireshark binary as it doesn't make sense to require that binary file to just get version info of that package in makefile.

[libvirt] [PATCH] network: Resolve Coverity FORWARD_NULL
by John Ferlan 17 Mar '15

17 Mar '15

The following is a long winded way to say this patch is avoiding a false positive. Coverity complains that calling networkPlugBandwidth() could eventually end up with a NULL dereference on iface->bandwidth because in the networkAllocateActualDevice there's a check of 'iface->bandwidth' before deciding to try to use the 'portgroup' if it exists or to not perferm the virNetDevBandwidthCopy if 'bandwidth' is not NULL. Later in networkPlugBandwidth the 'iface->bandwidth' is sourced from virDomainNetGetActualBandwidth - which would be either iface->bandwidth or (preferably) iface->data.network.actual->bandwidth which would have been filled in from either 'iface->bandwidth' or 'portgroup->bandwidth' back in networkAllocateActualDevice There *is* a check in networkCheckBandwidth for the result of the virDomainNetGetActualBandwidth being NULL and a return 1 based on that which would cause networkPlugBandwidth to exit properly and thus never hit the condition that Coverity complains about. However, since Coverity checks all paths - it somehow believes that a return of 0 by networkCheckBandwidth in this condition would end up causing the possible NULL dereference. The "fix" to silence Coverity is to not have networkCheckBandwidth also call virDomainNetGetActualBandwidth in order to get the ifaceBand, but rather have it accept it as an argument which causes Coverity to "see" that it's the exit condition of 1 that won't have the possible NULL dereference. Since we're passing that, I added the passing of iface->mac rather than passing iface as well. This just hopefully makes sure someone doesn't undo this in the future...

[libvirt] [PATCH] libxl: fix regression introduced by commit 4ab8cd77
by Jim Fehlig 16 Mar '15

16 Mar '15

Commit 4ab8cd77 added a check requiring input devices to have a bus type of VIR_DOMAIN_INPUT_BUS_USB, failing to start the domain otherwise. But virDomainDefParseXML adds implicit mouse and keyboard if a graphics device is configured. See calls to virDomainDefMaybeAddInput. The regression is fixed by removing the check requiring USB input devices, and skipping non-USB input devices when populating USB 'usbdevice' in libxl_domain_build_info struct.

[libvirt] [PATCH 00/12] More cleanup from IOThreads changes
by John Ferlan 16 Mar '15

16 Mar '15

During the review process a few things were pointed at as perhaps needing some adjustments based on what was done for IOThreads. Specifically a memory leak in PinVcpuFlags since PinIOThreads was just a copy of the Vcpu code and secondarily since the IOThreads code "reused" the virDomainVcpuPin* data structures and API's, those should change names to be more generic.

[libvirt] [PATCH] rpm-build: use pkg-config to detect wireshark presence
by Pavel Hrdina 16 Mar '15

16 Mar '15

Wireshark supports pkg-config since 1.11.3. Right now we build wireshark-dissectior tool as default trough rpm build only on fedora >= 21 and there is newer wireshark that supports pkg-config. If someone wants to build libvirt with wireshark-dissector against older wireshark, they should specify the location by hand. This patch is mainly to fix wrong dependency on wireshark binary as it doesn't make sense to require that binary file to just get version info of that package in makefile.

[libvirt] [libvirt-perl PATCHv2 0/2] Add virDomainGetIOThreads and virDomainPinIOThread bindings
by John Ferlan 16 Mar '15

16 Mar '15

v1: http://www.redhat.com/archives/libvir-list/2015-March/msg00352.html Since I essentially copied the vcpuinfo.pl example to create the iothreadsinfo.pl example, I figured I'd resend the patches again with the changes that ended up working which are slightly different than the review comment. The major difference being I needed to limit the unpack bits format. Instead of "b*", I found "b$nodeinfo->{cpus}" would print the just the cpu count bits. Made the same change to the vcpuinfo.pl example. I didn't modify the Virt.xs Safefree(info) check although it seems it would be possible if desired.

[libvirt] [PATCH] qemu: Check for negative port values in network drive configuration
by Erik Skultety 16 Mar '15

16 Mar '15

We interpret port values as signed int (convert them from char *), so if a negative value is provided in network disk's configuration, we accept it as valid, however there's an 'unknown cause' error raised later. This error is only accidental because we return the port value in the return code. This patch adds just a minor tweak to the already existing check so we reject negative values the same way as we reject non-numerical strings.

[libvirt] [PATCH] conf: fix use the wrong type for period
by Luyao Huang 16 Mar '15

16 Mar '15

https://bugzilla.redhat.com/show_bug.cgi?id=1140958 When we set period as unsigned int max value 4294967295 and start the vm, qemu will report error. This becuase we define period as a unsigned int and parse it as a unsigned int, but we use it as a int when set it via QMP in qemuMonitorJSONSetMemoryStatsPeriod, so 4294967295 turn to -1 when we send the QMP command. After check the qemu's code this value type should be int, and found a qemu commit 1f9296b for this values range. Seems no other hypervisor vm use this so i add a check when we parse it.

[libvirt] [PATCH v3] util: don't fail if no PortData is found while getting migrateData
by zhang bo 14 Mar '15

14 Mar '15

Introduced by f6a2f97e Problem Description: After multiple times of migrating a domain, which has an ovs interface with no portData set, with non-shared disk, nbd ports got overflowed. The steps to reproduce the problem: 1 define and start a domain with its network configured as: <interface type='bridge'> <source bridge='br0'/> <virtualport type='openvswitch'> </virtualport> <model type='virtio'/> <driver name='vhost' queues='4'/> </interface> 2 do not set the network's portData. 3 migrate(ToURI2) it with flag 91(1011011), which means: VIR_MIGRATE_LIVE VIR_MIGRATE_PEER2PEER VIR_MIGRATE_PERSIST_DEST VIR_MIGRATE_UNDEFINE_SOURCE VIR_MIGRATE_NON_SHARED_DISK 4 migrate success, but we got an error log in libvirtd.log: error : virCommandWait:2423 : internal error: Child process (ovs-vsctl --timeout=5 get Interface vnet1 external_ids:PortData) unexpected exit status 1: ovs-vsctl: no key "PortData" in Interface record "vnet1" column external_ids 5 migrate it back, migrate it , migrate it back, ....... 6 nbd port got overflowed. The reasons for the problem is : 1 virNetDevOpenvswitchGetMigrateData() takes it as wrong if no portData is available for the ovs interface of a domain. (We think it's not appropriate, as portData is just OPTIONAL) 2 in func qemuMigrationBakeCookie(), it fails in qemuMigrationCookieAddNetwork(), and returns with -1. qemuMigrationCookieAddNBD() is not called thereafter, and mig->nbd is still NULL. 3 However, qemuMigrationRun() just *WARN* if qemuMigrationBakeCookie() fails, migration still successes. cookie is NULL, it's not baked on the src side. 4 On the destination side, it would alloc a port first and then free the nbd port in COOKIE. But the cookie is NULL due to qemuMigrationCookieAddNetwork() failure at src side. thus the nbd port is not freed. In this patch, we add "--if-exists" option to make ovs-vsctl not raise error if there's no portData available. Further more, because portData may be NULL in the cookie at the dest side, check it before setting portData.

[libvirt] Applying for GSoC project 'Introducing job control to the storage driver' in libvirt
by Taowei Luo 13 Mar '15

13 Mar '15

Hello, everyone. I'm Taowei Luo. A participator in Google Summer of Code last year for the project rewriting vbox driver in libvirt. I am so glad that my project isn't found in this year's GSoC project list :) Having a nice experience last year, libvirt is my top option to join the GSoC 2015. And my interesting project is “Introducing job control to the storage driver”. I have read some materials about this project. Including I noticed that Tucker had attempted it last year. It seems he didn't make it through the final evaluation. During his working, some discussion were made in mail-list. It is really inspiring to me. So I have some basic ideas for now. The project requires job control functions (at least, reporting the progress) in storage driver. Obviously, it contains two part. First find codes that really do the storage work which may take a long period and can be asynchronized. Then, extract it to the job control part so make it under the control. It would not be hard to find codes that really need asynchronization. Maybe by dumping the debug message and tracing the function calls. So the big part is design the APIs for job control. I think the goal for API design is not only make it workable but also make it reasonable and extendable. To achieve this, a lot of details were discussed in last year's proceeding. I summered it and add my own opinion. Parallel jobs: The idea result is that several jobs work in parallel and libvirt monitors and controls it. There are two ways for parallel: thread and process. I prefer process. In process, we can easier implement the idea of *control* by signal. Process has better independence than thread. What's more, it is a low coupling design. Synchronization: process can use system level lock to make sure it obtain the resources. If the process can't obtain it could exit with failure (or wait). In process, we can leave most resource competition handling by OS. If thread is used instead, we need to think about resource competition between libvirt and other process, and at the same time, those competitions in libvirt thread. Management: We execute those asynchronous codes in a new process. In libvirt, it invokes those processes with parsed arguments. Libvirtd would have a process pool to store the pids and some attached information for each process. Signal would be used to communicate between process and libvirt. Expandability: Some other jobs like domain migration could be in implemented under this design. It's all about creating new jobs with parsed arguments, which tells the child process what to do and what resources they need. Privacy: If new jobs are created in process, user may access the process directly and not noticing libvirt. Function sigaction(), which provides the pid of sending process, could be used to register responding functions. Meanwhile, atexit() register functions that execute when the process is going to exit. It is helpful on notifying libvirtd the end of the job. What already have: Besides the discussion, some other resources would be helpful for this project. qemu has a prototype for job control in migration. We already have gnulib and tools in util/virprocess.h and util/virthread.h to achieve parallel. When undertaking, I would firstly implement the job control part. It would have some basic functions. Make one storage API work in it. Then, adding job control support for the rest APIs. This is all about what I came up with. Maybe those ideas are old and repeating. But I think it is a workable plan. Waiting for feedback. Regards, Taowei

[libvirt] [PATCH v4 4/4] migration: Expose 'cancelling' status to user
by zhanghailiang 13 Mar '15

13 Mar '15

'cancelling' status was introduced by commit 51cf4c1a, mainly to avoid a possible start of a new migration process while the previous one still exists. But we didn't expose this status to user, instead we returned the 'active' state. Here, we expose it to the user (such as libvirt), 'cancelling' status only occurs for a short window before the migration aborts, so for users, if they cancel a migration process, it will observe 'cancelling' status occasionally. Testing revealed that with older libvirt (anything 1.2.13 or less) will print an odd error message if the state is seen, but that the migration is still properly cancelled. Newer libvirt will be patched to recognize the new state without the odd error message.

[libvirt] [PATCH v2] qemu: read backing chain names from qemu
by Eric Blake 13 Mar '15

13 Mar '15

https://bugzilla.redhat.com/show_bug.cgi?id=1199182 documents that after a series of disk snapshots into existing destination images, followed by active commits of the top image, it is possible for qemu 2.2 and earlier to end up tracking a different name for the image than what it would have had when opening the chain afresh. That is, when starting with the chain 'a <- b <- c', the name associated with 'b' is how it was spelled in the metadata of 'c', but when starting with 'a', taking two snapshots into 'a <- b <- c', then committing 'c' back into 'b', the name associated with 'b' is now the name used when taking the first snapshot. Sadly, older qemu doesn't know how to treat different spellings of the same filename as identical files (it uses strcmp() instead of checking for the same inode), which means libvirt's attempt to commit an image using solely the names learned from qcow2 metadata fails with a cryptic: error: internal error: unable to execute QEMU command 'block-commit': Top image file /tmp/images/c/../b/b not found even though the file exists. Trying to teach libvirt the rules on which name qemu will expect is not worth the effort (besides, we'd have to remember it across libvirtd restarts, and track whether a file was opened via metadata or via snapshot creation for a given qemu process); it is easier to just always directly ask qemu what string it expects to see in the first place. As a safety valve, we validate that any name returned by qemu still maps to the same local file as we have tracked it, so that a compromised qemu cannot accidentally cause us to act on an incorrect file. * src/qemu/qemu_monitor.h (qemuMonitorDiskNameLookup): New prototype. * src/qemu/qemu_monitor_json.h (qemuMonitorJSONDiskNameLookup): Likewise. * src/qemu/qemu_monitor.c (qemuMonitorDiskNameLookup): New function. * src/qemu/qemu_monitor_json.c (qemuMonitorJSONDiskNameLookup) (qemuMonitorJSONDiskNameLookupOne): Likewise. * src/qemu/qemu_driver.c (qemuDomainBlockCommit) (qemuDomainBlockJobImpl): Use it.

[libvirt] logging: how about adding a ProcessName field in logging file?
by zhang bo 13 Mar '15

13 Mar '15

Suppose there are 3 or more clients of libvirt: 1)nova 2)bash virsh commands 3)user customized ELF 4)etc.... The env LIBVIRT_DEBUG and LIBVIRT_LOG_OUTPUTS affects all of these clients, thus, they will all accumulate the logs into *ONE* file set by LIBVIRT_LOG_OUTPUTS. eg: [2015-03-07 00:33:30]: 103674: info : virDomainShutdown:3242 : enter virDomainShutdown domainname=VMName [2015-03-07 00:33:41]: 103674: info : virDomainShutdown:3253 : domain VMName shutted down [2015-03-13 00:53:44]: 5073: info : libvirt version: 1.2.7 [2015-03-13 00:53:44]: 5034: info : libvirt version: 1.2.7 [2015-03-13 00:53:44]: 5073: error : virNetSocketReadWire:1475 : End of file while reading data: Input/output error note: 103674: bash virsh command 5037: nova if we don't know that 103674 is just a virsh command, and suspect that it's nova, time would be wasted to find out who's the criminal. The improved log would be: [2015-03-07 00:33:30]: virsh: 103674: info : virDomainShutdown:3242 : enter virDomainShutdown domainname=VMName [2015-03-07 00:33:41]: virsh: 103674: info : virDomainShutdown:3253 : domain VMName shutted down [2015-03-13 00:53:44]: nova: 5073: info : libvirt version: 1.2.7 [2015-03-13 00:53:44]: myProc1: 5034: info : libvirt version: 1.2.7 [2015-03-13 00:53:44]: nova: error : virNetSocketReadWire:1475 : End of file while reading data: Input/output error So, here's the qeustion: Is it neccssary to add a ProcessName field in the logging file? if so, I'd like to apply a patch for this. thank you in advance.

[libvirt] Should logging in the library set its default outputs?
by zhang bo 13 Mar '15

13 Mar '15

If the env LIBVIRT_DEBUG and LIBVIRT_LOG_OUTPUTS are not set, the logging in the library would not log into any file. So: Is it necessary to set the default level and outputs in virGlobalInit(), just in case the maintainer forgets to set the ENVs ? Thanks in advance.

Jeff, thanks for the idea on how to solve the problem without touching qemu (of course, it would still be nice to teach qemu to respect inode equivalence rather than relying on streq, and even nicer for libvirt to use node names instead of file names, but those can be later patches without holding up VDSM now). src/qemu/qemu_driver.c | 28 +++++++------- src/qemu/qemu_monitor.c | 20 +++++++++- src/qemu/qemu_monitor.h | 8 +++- src/qemu/qemu_monitor_json.c | 87 +++++++++++++++++++++++++++++++++++++++++++- src/qemu/qemu_monitor_json.h | 9 ++++- 5 files changed, 134 insertions(+), 18 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 51b30b7..e540001 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -15932,9 +15932,6 @@ qemuDomainBlockJobImpl(virDomainObjPtr vm, goto endjob; if (baseSource) { - if (qemuGetDriveSourceString(baseSource, NULL, &basePath) < 0) - goto endjob; - if (flags & VIR_DOMAIN_BLOCK_REBASE_RELATIVE) { if (!virQEMUCapsGet(priv->qemuCaps, QEMU_CAPS_CHANGE_BACKING_FILE)) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", @@ -15972,8 +15969,12 @@ qemuDomainBlockJobImpl(virDomainObjPtr vm, } qemuDomainObjEnterMonitor(driver, vm); - ret = qemuMonitorBlockJob(priv->mon, device, basePath, backingPath, - speed, mode, async); + if (baseSource) + basePath = qemuMonitorDiskNameLookup(priv->mon, device, disk->src, + baseSource); + if (!baseSource || basePath) + ret = qemuMonitorBlockJob(priv->mon, device, basePath, backingPath, + speed, mode, async); if (qemuDomainObjExitMonitor(driver, vm) < 0) ret = -1; if (ret < 0) { @@ -16703,12 +16704,6 @@ qemuDomainBlockCommit(virDomainPtr dom, VIR_DISK_CHAIN_READ_WRITE) < 0)) goto endjob; - if (qemuGetDriveSourceString(topSource, NULL, &topPath) < 0) - goto endjob; - - if (qemuGetDriveSourceString(baseSource, NULL, &basePath) < 0) - goto endjob; - if (flags & VIR_DOMAIN_BLOCK_COMMIT_RELATIVE && topSource != disk->src) { if (!virQEMUCapsGet(priv->qemuCaps, QEMU_CAPS_CHANGE_BACKING_FILE)) { @@ -16739,9 +16734,14 @@ qemuDomainBlockCommit(virDomainPtr dom, disk->mirrorJob = VIR_DOMAIN_BLOCK_JOB_TYPE_ACTIVE_COMMIT; } qemuDomainObjEnterMonitor(driver, vm); - ret = qemuMonitorBlockCommit(priv->mon, device, - topPath, basePath, backingPath, - speed); + basePath = qemuMonitorDiskNameLookup(priv->mon, device, disk->src, + baseSource); + topPath = qemuMonitorDiskNameLookup(priv->mon, device, disk->src, + topSource); + if (basePath && topPath) + ret = qemuMonitorBlockCommit(priv->mon, device, + topPath, basePath, backingPath, + speed); if (qemuDomainObjExitMonitor(driver, vm) < 0) { ret = -1; goto endjob; diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index d869a72..cf7dc5e 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -1,7 +1,7 @@ /* * qemu_monitor.c: interaction with QEMU monitor console * - * Copyright (C) 2006-2014 Red Hat, Inc. + * Copyright (C) 2006-2015 Red Hat, Inc. * Copyright (C) 2006 Daniel P.

[libvirt] [PATCH v2] virnetdev: fix build with old kernel
by Pavel Hrdina 12 Mar '15

12 Mar '15

Commit c9027d8f added a detection of NIC HW features, but some of them are not available in old kernel. Very old kernels lack enum ethtool_flags and even if this enum is present, not all values are available for all kernels. To be sure that we have everything in kernel that we need, we must check for existence of most of that flags, because only few of them were defined at first. Also to successfully build libvirt with older kernel we need to include <linux/types.h> before <linux/ethtool.h> to have __u32 and friends defined.

[libvirt] [PATCH v3 00/15] Drop network driver lock
by Michal Privoznik 12 Mar '15

12 Mar '15

Well, this is interesting. I've turned the virNetworkObjList into using a virHash. And even though the performance in my testing (using the very same test program as in previous versions of the patch set) increased. Without these patches, the test program took 56s to finish. With these patches (that is with virHash table) it takes 46s, which is better. But previously, with network objects stored in flat array I was able to get somewhere around 23s! I wonder what may be the cause. NB, nearly all patches in the series have been ACKed already, but since I'm switching the virNetworkObjList internals, I'm posting them again.

[libvirt] [PATCH] virnetdev: fix build with old kernel
by Pavel Hrdina 11 Mar '15

11 Mar '15

Commit c9027d8f added a detection of NIC HW features, but some of them are not available in old kernel. Very old kernels lack enum ethtool_flags and even if this enum is present, not all values are available for all kernels. To be sure that we have everything in kernel that we need, we must check for existence of newest value which is ETH_FLAG_TXVLAN. Only then we can be sure that the feature detection can be successfully built.

[libvirt] [PATCH] RNG: Allow multiple parameters to be passed to an interface filter
by Michal Privoznik 11 Mar '15

11 Mar '15

Our code supports that for ages. When using a <filterref/> to an <interface/> several parameters can be passed to the filter. Later, when building firewall rules, parameters are substituted for their values. However, our RNG schema allowed only one parameter to be passed.

[libvirt] [PATCH 0/4] parallels: fix different domain define parameters
by Maxim Nestratov 11 Mar '15

11 Mar '15

Actually our checking for unsupported parameters is too strict about cpumask, vcpupin and NUMA parameters and in general wrong. First of all, we do support cpumask and consequently we don't have to prevent domain definition in case cpumask is specified. Also we should allow vcpupin parameters if they don't contradict with common cpumask. NUMA checking was also wrong because def->numa is always allocated. Here we check that its content is not specified. Maxim Nestratov (4): parallels: cpumask support parallels: don't forget to unlock domain in parallelsDomainHasManagedSaveImage parallels: prevent domain define only if NUMA is really specified parallels: prevent domain define only if vcpupin is specified

[libvirt] [PATCH] {domain, network}_conf: disable autostart when deleting config
by Michael Chapman 11 Mar '15

11 Mar '15

Undefining a running, autostarted domain removes the autostart link, but dom->autostart is not cleared. If the domain is subsequently redefined, libvirt thinks it is already autostarted and will not create the link even if requested: # virsh dominfo example | grep Autostart Autostart: enable # ls /etc/libvirt/qemu/autostart/example.xml /etc/libvirt/qemu/autostart/example.xml # virsh undefine example Domain example has been undefined # virsh define example.xml Domain example defined from example.xml # virsh dominfo example | grep Autostart Autostart: enable # virsh autostart example Domain example marked as autostarted # ls /etc/libvirt/qemu/autostart/example.xml ls: cannot access /etc/libvirt/qemu/autostart/example.xml: No such file or directory This commit ensures dom->autostart is cleared whenever the config and autostart link (if present) are removed. The bridge network driver cleared this flag itself in networkUndefine. This commit moves this into virNetworkDeleteConfig for symmetry with virDomainDeleteConfig, and to ensure it is not missed in future network drivers.

================================================================= CALL FOR PAPERS 10th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '15) held in conjunction with Euro-Par 2015, August 24-28, Vienna, Austria (Springer LNCS) ================================================================= Date: August 25, 2015 Workshop URL: http://vhpc.org Paper Submission Deadline: May 22, 2015 CALL FOR PAPERS Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, cloud environments, and increasingly in HPC as well. Providers need to dynamically manage complex infrastructures in a seamless fashion for varying workloads and hosted applications, independently of the customers deploying software or users submitting highly dynamic and heterogeneous workloads. Thanks to virtualization, we have the ability to manage vast computing and networking resources dynamically and close to the marginal cost of providing the services, which is unprecedented in the history of scientific and commercial computing. Various virtualization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple under-utilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization, with its capability to isolate multiple user-space environments and to allow for their co-existence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; I/O Virtualization allows physical network adapters to take traffic from multiple VMs; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology and IP addressing, provides the fundamental ground on top of which evolved network services can be realized with an unprecedented level of dynamicity and flexibility; These technologies have to be inter-mixed and integrated in an intelligent way, to support workloads that are increasingly demanding in terms of absolute performance, responsiveness and interactivity, and have to respect well-specified Service- Level Agreements (SLAs), as needed for industrial-grade provided services. Indeed, among emerging and increasingly interesting application domains for virtualization, we can find big-data application workloads in cloud infrastructures, interactive and real-time multimedia services in the cloud, including real-time big-data streaming platforms such as used in real-time analytics supporting nowadays a plethora of application domains. Distributed cloud infrastructures promise to offer unprecedented responsiveness levels for hosted applications, but that is only possible if the underlying virtualization technologies can overcome most of the latency impairments typical of current virtualized infrastructures (e.g., far worse tail-latency). The Workshop on Virtualization in High-Performance Cloud Computing (VHPC) aims to bring together researchers and industrial practitioners facing the challenges posed by virtualization in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems of tomorrow. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections, and lightning talks, limited to 5 minutes. Presentations may be accompanied by interactive demonstrations.
