[libvirt] [RFC] Can we error out early for unknown device models?
by Martin Kletzander 27 Oct '14

27 Oct '14

Hi everyone, I had this idea that since we are probing QEMU binaries for devices using 'qom-list-types', we could store that data in the capabilities and check whether device models are supported before starting QEMU. We do that for _some newer_ devices, but this would be global. It would help out particularly with devices like the following one, for example: <interface type='network'> <source network='default'/> <model type='non-existing_device'/> </interface> where we simply construct QEMU command-line with that device model and it then properly errors out: error: internal error: process exited while connecting to monitor: qemu-system-x86_64: -device non-existing_device,...: Parameter 'driver' expects device type This would be easy to achieve with current data unless there are some models hidden from qom-list-types' output. I hope there are none. When I checked the output of 'qemu-kvm -device \?', the devices listed there are separated into categories and have buses assigned to them and that lead me to another idea. What if that data is added to qom-list-types' output and used in libvirt as well? We could then solve another annoying cases like misusing devices or plugging them into unsupported buses. Although I don't know any person who would do such a thing, even when solving the first idea, there'd still be a possibility to do a thing like: <interface type='network'> <source network='default'/> <model type='AC97'/> </interface> This idea is obviously meant for the QEMU driver, but if there's something similar in other drivers, it might be useful as well. I'd be interested in any feedback and welcome any ideas to whether it is useful, how the storing should be done or even if it's something we want to have or not. Have a nice day, Martin

[libvirt] Coming release plans for libvirt-1.2.10
by Daniel Veillard 27 Oct '14

27 Oct '14

It's already the end of the month and I didn't pushed plans yet (forgot !) for the coming release. We have only until the end of the week to get to next month, o we should freeze this week. There isn't that many commits yet sine 1.2.9, less than 140 and a number of them are the large splitting changes for the hypervisor driver. So a slightly smaller freeze may be just fine, I'm tempted to push the rc1 for 1.2.10 freeze very early on Wednesday and targetting a release out next Monday. Hopefully that works for everyone, 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] [PATCH] util: eliminate "use after free" in callers of virNetDevLinkDump
by Laine Stump 26 Oct '14

26 Oct '14

virNetDevLinkDump() gets a message from netlink into "resp", then calls nlmsg_parse() to fill the table "tb" with pointers into resp. It then returns tb to its caller, but not before freeing the buffer at resp. That means that all the callers of virNetDevLinkDump() are examining memory that has already been freed. This can be verified by filling the buffer at resp with garbage prior to freeing it (or, I suppose, just running libvirtd under valgrind) then performing some operation that calls virNetDevLinkDump(). The code has been like this ever since virNetDevLinkDump() was written - the original author didn't notice it, and neither did later additional users of the function. It has only been pure luck (or maybe a lack of heavy load, and/or maybe an allocation algorithm in malloc() that delays re-use of just-freed memory) that has kept this from causing errors, for example when configuring a PCI passthrough or macvtap passthrough network interface. The solution taken in this patch is the simplest - just return resp to the caller along with tb, then have the caller free it after they are finished using the data (pointers) in tb. I alternately could have made a cleaner interface by creating a new struct that put tb and resp together along with a vir*Free() function for it, but this function is only used in a couple places, and I'm not sure there will be additional new uses of virNetDevLinkDump(), so the value of adding a new type, extra APIs, etc. is dubious. --- src/util/virnetdev.c | 26 +++++++++++++++++--------- src/util/virnetdev.h | 2 +- src/util/virnetdevvportprofile.c | 17 ++++++++++++----- 3 files changed, 30 insertions(+), 15 deletions(-) diff --git a/src/util/virnetdev.c b/src/util/virnetdev.c index db5623a..c22a0e6 100644 --- a/src/util/virnetdev.c +++ b/src/util/virnetdev.c @@ -1353,23 +1353,25 @@ static struct nla_policy ifla_vf_policy[IFLA_VF_MAX+1] = { /** * virNetDevLinkDump: * - * @ifname: The name of the interface; only use if ifindex < 0 - * @ifindex: The interface index; may be < 0 if ifname is given - * @nlattr: pointer to a pointer of netlink attributes that will contain - * the results + * @ifname: The name of the interface; only use if ifindex <= 0 + * @ifindex: The interface index; may be <= 0 if ifname is given + * @data: Gets a pointer to the raw data from netlink. + MUST BE FREED BY CALLER!

Similar to the previous series, this splits up the libvirt.h.in header file to many pieces.

[libvirt] [RFC] Add support for NIC offload discovery
by Chapman, James P 24 Oct '14

24 Oct '14

Currently libvirt provides lots of useful information on the HW capabilities of the host and its attached devices. I'm interested in extending the HW capability discovery of libvirt, to a point where it is capable of discovering the HW offload capabilities of host PCI devices. Take a NIC for example, this feature would enable libvirt discover the supported NIC offload features, csum, tso, etc. So where might a feature like this be used. Consider an Openstack deployment, a VM may have a workload that depends on specific NIC HW offload capabilities in order to stay within certain throughput, CPU utilisation or latency thresholds. For this scenario, it's important that the VM is placed on a host with PCI devices that provide the required NIC HW offload capabilities. If libvirt could provide this functionality, this information could be used during the VM scheduling phase when all nodes are evaluated for their suitability. >From what I understand, libvirt currently uses ioctl's to get the NIC state, MTU, etc. Could the ethtool ioctl framework be used to discover the HW offload features provided by the hosts network controllers. E.g. * ETHTOOL_GRXCSUM * ETHTOOL_GTXCSUM * ETHTOOL_GTSO * ETHTOOL_GFLAGS So I'm looking for your opinions on this feature proposal, does it make sense, is it already being worked on. Thanks James

[libvirt] [PATCH 00/12] Split up large driver files
by Daniel P. Berrange 23 Oct '14

23 Oct '14

This patch series splits up the src/driver.h and src/libvirt.c files into a number of smaller pieces. The driver.h file gets split based on the the driver type, while libvirt.c gets split slightly different based on the object type. The reason for the difference is that the hypervisor driver is rather large, so its useful to split the domain, domain snapshot and connect/node APIs into separate files. There will be much more to follow this series. Just posting this start now since it will be painful to rebase.... Daniel P.

[libvirt] Libvirt clock/time settings doubt.
by Julio Faracco 22 Oct '14

22 Oct '14

Hi everyone! What is the method/function responsible to setup time settings in libvirt? Considering the example of libvirt documentation. <clock offset='localtime'> <timer name='rtc' tickpolicy='catchup' track='guest'> <catchup threshold='123' slew='120' limit='10000'/> </timer> <timer name='pit' tickpolicy='delay'/> </clock> ... I know where this XML will be parsed. But I don't know where libvirt will pass clock/time settings to QEMU. Can somebody explain to me or send me a documentation about it? I passed two weeks trying to discover the sequence of function calls. Thanks guys! *--* *Julio Cesar Faracco*

[libvirt] [PATCH 0/5] parallels: continue rewriting code to use sdk
by Dmitry Guryanov 22 Oct '14

22 Oct '14

This patch series replaces a series of functions, which retieve different domains info and modifies domains state with new ones, which use parallels sdk instead of executing prlctl command. These functions don't use cached domains list _parallelsConn.domains, so when we rewrite all code, we will be able to remove it.

[libvirt] [PATCH v4] network: Add bandwidth support to ethernet interfaces
by Anirban Chakraborty 21 Oct '14

21 Oct '14

v4: Changed function virNetDevSupportBandwidth to use switch statement. Fixed syntax issues Fold the two patches into one as the second patch was a one liner v3: Addressed issues pointed out in V2 Split into two patches v2: Addressed comments raised in review of V1. Consolidate calls to virNetDevBandwidthSet. Clear bandwidth settings when the interface is detached or domain destroyed. v1: Ethernet interfaces in libvirt currently do not support bandwidth setting. For example, following xml file for an interface will not apply these settings to corresponding qdiscs. <interface type="ethernet"> <mac address="02:36:1d:18:2a:e4"/> <model type="virtio"/> <script path=""/> <target dev="tap361d182a-e4"/> <bandwidth> <inbound average="984" peak="1024" burst="64"/> <outbound average="2000" peak="2048" burst="128"/> </bandwidth> </interface> Signed-off-by: Anirban Chakraborty <abchak(a)juniper.net> --- src/conf/domain_conf.h | 21 +++++++++++++++++++++ src/lxc/lxc_driver.c | 3 +++ src/lxc/lxc_process.c | 18 +++++++++--------- src/qemu/qemu_command.c | 25 +++++++++++++++++++------ src/qemu/qemu_command.h | 2 ++ src/qemu/qemu_driver.c | 3 +++ src/qemu/qemu_hotplug.c | 12 ++++++++++++ src/qemu/qemu_process.c | 3 +++ src/util/virnetdevmacvlan.c | 10 ---------- src/util/virnetdevmacvlan.h | 1 - 10 files changed, 72 insertions(+), 26 deletions(-) diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index afa3da6..59fdfb2 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -2848,4 +2848,25 @@ int virDomainObjSetMetadata(virDomainObjPtr vm, bool virDomainDefNeedsPlacementAdvice(virDomainDefPtr def) ATTRIBUTE_NONNULL(1);

[libvirt] [PATCH] qemu: move setting emulatorpin ahead of monitor showing up
by Wang Rui 21 Oct '14

21 Oct '14

From: Zhou yimin <zhouyimin(a)huawei.com> If VM is configured with many devices(including passthrough devices) and large memory, libvirtd will take seconds(in the worst case) to wait for monitor. In this period the qemu process may run on any PCPU though I intend to pin emulator to the specified PCPU in xml configuration. Actually qemu process takes high cpu usage during vm startup. So this is not the strict CPU isolation in this case.

[libvirt] Implement quorum support.
by Matthias Gatto 20 Oct '14

20 Oct '14

Hello, I'm implementing quorum in libvirt. I've try to follow this proposal: http://www.redhat.com/archives/libvir-list/2014-May/msg00546.html At this point I've done this: - add all the field need by quorum in _virStorageSource (nBackingStores, threshold). - handle more than one backing store in virStorageSource by adding a function virStorageSourcePushBackingStore - add support of the quorum syntax for the xml parser. so now i have to work on qemuBuildDriveStr But I've a problem: in qemu a child of a quorum is a BlockDriverState, where it's a virStorageSource in libvirt, so a child in qemu contain more information than a backingStore in libvirt(blockinfo, throttle...). I think about several solution for this problem: - I can handle quorum's child differently than backingStore and create a "virDomainDiskDefPtr childs" field in virDomainDiskDef or virStorageSource. - I can change the virStorageSourcePtr backingStore, to virDomainDiskDefPtr backingStore, and move the field to backingStore to virDomainDiskDef. -I can move all the field need by a quorum's child from virStorageSource to virDomainDiskDef. But i don't know which solution is the best for libvirt, how do you think i can handle this problem ? Best regards, Matthias

[libvirt] [PATCH] conf: tests: fix virDomainNetDefFormat for vhost-user in client mode
by Maxime Leroy 20 Oct '14

20 Oct '14

The mode attribute is required for the source element of vhost-user. Thus virDomainNetDefFormat should always generate a xml with it, and not only when the mode is server. The commit fixes the issue. And it adds a vhostuser interface in 'client' mode to qemuxml2argv-net-vhostuser.(args|xml) to test this usecase.

[libvirt] [PATCH] docs: apps: Update references to virt-p2v and virt-v2v.
by Richard W.M. Jones 20 Oct '14

These tools have been rewritten upstream, so you don't need to link to the old tools, link to the new ones and mention they are part of libguestfs. Also remove the link to "Poor man's P2V".

[libvirt] [PATCH] esx: Simplify VI (vSphere) API and VMware product version handling
by Matthias Bolte 19 Oct '14

19 Oct '14

Store version numbers in this format version = 1000000 * major + 1000 * minor + micro produces by virParseVersionString instead of dedicated enums. Split the complex esxVI_ProductVersion enum into a simpler sxVI_ProductLine enum and a product version number. Relax API and product version number check to accept anything that is equal or greater than the supported minimum version. VMware ESX went through 3 major version and constantly stayed backward compatible. This commit assumes that this will be true for future versions. --- src/esx/esx_driver.c | 59 +++++--------- src/esx/esx_vi.c | 215 ++++++++++++++++++++++++++------------------------- src/esx/esx_vi.h | 55 +++---------- 3 files changed, 140 insertions(+), 189 deletions(-) diff --git a/src/esx/esx_driver.c b/src/esx/esx_driver.c index 39784b9..4f62774 100644 --- a/src/esx/esx_driver.c +++ b/src/esx/esx_driver.c @@ -646,9 +646,9 @@ esxConnectToHost(esxPrivate *priv, esxVI_String *propertyNameList = NULL;

[libvirt] ANNOUNCE: libguestfs 1.28 released
by Richard W.M. Jones 18 Oct '14

18 Oct '14

I'm pleased to announce libguestfs 1.28, a library and set of tools for accessing and modifying virtual machine disk images. This release took 7 months of work by a considerable number of people, and has many new features (see release notes below), including new 'virt-v2v' and 'virt-p2v' tools for importing guests from foreign hypervisors to KVM, and 'virt-log' which is a tool for extracting log files from guests (including Windows). You can get libguestfs 1.28 here: Main website: http://libguestfs.org/ Source: http://libguestfs.org/download/1.28-stable/ You will also need latest supermin from here: http://libguestfs.org/download/supermin/ Fedora 21: http://koji.fedoraproject.org/koji/packageinfo?packageID=8391 It will appear as an update for F21 in about a week. Debian/experimental coming soon, see: https://packages.debian.org/experimental/libguestfs0 [ From http://libguestfs.org/guestfs-release-notes.1.html ] RELEASE NOTES FOR LIBGUESTFS 1.28 New features Tools virt-v2v(1) and virt-p2v(1) are tools for converting from foreign hypervisors (such as VMware or Xen) or physical machines, to KVM. These tools were previously a separate project. The code for both tools has been integrated into the libguestfs tree. As part of the refactoring, virt-p2v has been rewritten (from Ruby, now C), and virt-v2v now uses several modern features of qemu which make it run many times faster than before. virt-v2v(1) can import from: VMware vCenter, VMware OVA files, local disk files, libvirt, RHEL 5 Xen. It can output to: oVirt or Red Hat Enterprise Virtualization (RHEV-M), OpenStack Glance, libvirt, qemu, local disk files. virt-log(1) is a new tool for listing log files from guests. It supports a variety of guests including Linux traditional, Linux using journal, and Windows event log. virt-builder(1) has a new --machine-readable option to make it simpler to consume virt-builder from other programs. New virt-builder(1) and virt-customize(1) --chmod option. virt-sysprep(1) will now remove: systemd journals, anaconda logs, lightdm logs, debian-installer files, apt logs, exim logs, ConsoleKit logs, firewalld logs, grubby logs, proftpd logs, libvirt/libxml logs, and several other log files. The virt-sysprep user-account operation is now able to remove or keep particular user accounts. (Pino Toscano). New guestmount(1) --fd option, allowing you to run guestmount captive under another process. virt-sparsify(1) has a new --tmp option allowing you to precisely control where temporary files are stored. virt-sparsify(1) can now write to a block device. virt-customize(1) and virt-sysprep(1) now support adding firstboot scripts to Windows guests. virt-cat(1), virt-edit(1), virt-ls(1) now support the -m option, allowing you to override automatic inspection of guests and instead specify where to mount partitions (Pino Toscano). The virt tools now have coloured output: green for OK, red for errors, blue for warnings. Language bindings You can build a Python distribution using make -C python sdist Ruby bindings have switched from Test::Unit to MiniTest. The Java bindings are now compatible with OpenJDK 8 (Pino Toscano). Inspection Oracle Linux is returned as oraclelinux (Nikos Skalkotos). Linux guests which do not have /etc/fstab can now be handled (Pino Toscano). Minix is returned as minix (Pino Toscano). Architectures Aarch64 (64 bit ARM) support has been added. Inspection and the guestfs_file_architecture call can now recognize arm (32 bit) and aarch64 guests. Security CVE-2014-0191 Network usage and entity resolution in XML parsing Libguestfs previously used unsafe libxml2 APIs for parsing libvirt XML. These APIs defaulted to allowing network connections to be made when certain XML documents were presented. Using a malformed XML document it was also possible to exhaust all CPU, memory or file descriptors on the machine. Since the libvirt XML comes from a trusted source (the libvirt daemon) it is not thought that this could have been exploitable. This was fixed in libguestfs ≥ 1.27.9 and the fix was backported to stable versions ≥ 1.26.2, ≥ 1.24.9, ≥ 1.22.10 and ≥ 1.20.13. (Thanks: Dan Berrange, Pino Toscano). Shellshock (bash CVE-2014-6271) This bash bug indirectly affects libguestfs. For more information see: https://www.redhat.com/archives/libguestfs/2014-September/msg00252.html API New APIs guestfs_clear_backend_setting guestfs_get_backend_setting guestfs_set_backend_setting Use these APIs to set individual backend settings. guestfs_cpio_out Convert a directory within the disk image to cpio format. guestfs_journal_get_realtime_usec Fetch precise journal times, see sd_journal_get_realtime_usec(3). guestfs_lstatns guestfs_lstatnslist guestfs_statns Enhanced versions of guestfs_lstat, guestfs_lstatlist, guestfs_stat which return nanosecond timestamps. Build changes Libguestfs can now be built with qemu 2.x. Add support for packaging the appliance on Mageia (Joseph Wang, Thierry Vignaud). Augeas is now a required dependency. Flex and bison are now required dependencies. Internals User-Mode Linux (UML) is no longer a supported backend (although still available). It will be supported again once someone steps in and fixes various regressions and brokenness in the UML (Linux) kernel. You can now connect gdb to qemu by specifying LIBGUESTFS_BACKEND_SETTINGS=gdb Serial BIOS (sgabios) is now used by the libvirt backend (on x86 only) so that we see early BIOS messages. For the OCaml virt tools, exceptions are now handled and printed by a common function. A GCC warning about large stack frames is now enabled by default. Several places that used large arrays and structures on the stack have been fixed. There is now a test for booting the appliance repeatedly. Useful for finding kernel leaks. See: tests/qemu/qemu-boot.c There is a test for testing the speed of various qemu features such as virtio-serial uploads and block device writes. See: tests/qemu/qemu-speed-test.c GCC warnings are now enabled for OCaml-C bindings in the OCaml virt tools. The code for editing files used by virt-edit(1), guestfish(1) edit command, virt-customize(1) --edit option and more is now shared between all these utilities (thanks Pino Toscano). The FUSE tests were rewritten in C to ensure finer control over how system calls are tested. The update-bugs.sh script has been fixed so it should no longer create an empty BUGS file if the Bugzilla server is unavailable. The virt-resize(1) tests now use a stochastic method to ensure much deeper and broader testing. When the network is enabled, the appliance now uses DHCP to acquire an IP address. If libvirt is being used then the appliance will connect to virbr0 (can be overridden by setting LIBGUESTFS_BACKEND_SETTINGS=network_bridge=<some_bridge>). This enables full-featured network connections, with working ICMP, ping and so on.

[libvirt] [PATCHv2 0/4] Another attempt at improving virsh autocompletion
by Solly Ross 18 Oct '14

18 Oct '14

Version 2: Electric Boogaloo Version 1: https://www.redhat.com/archives/libvir-list/2014-March/msg01898.html This version of the patch introduces the following new things: - Tests (a whole bunch of them, in fact)! - A new `complete` command to run get newline-separated completion results from the command line - Support for completing partial quotes (e.g. `virsh complete "fake-command ab \"i "`) - Passing the syntax checks (sorry about that) A brief overview of the patch set follows: 1. Extract parsing logic from the vshCommandParse so that it can be used elsewhere. The new method returns states and sets passed in pointers. Calling methods can interpret these states and deal with them as needed (completion ignores many, while vshCommandParse throws errors). 2. Implement (and test!) an improved completion engine with support for virsh quoting rules, flags, positional arguments, no duplication, and more. 3. Add (and test!) a method for retrieve a global vshControl object should readline be enabled. This allows for "smart completion" of options like "domain". 4. Extract the domain listing code from virsh-domain-monitor, and move it to virsh-completer. Implement a domain completer, which is then used for all the cases of "domain" options (note that it current does not have any flags specified for which commands should list active vs inactive domains, as this commit is mainly to allow people to test out "smart completion") Solly Ross (4): Improve virsh autocompletion (extract parser) Improve virsh autocompletion (base framework) Improve virsh autocompletion (global ctl object) Improve virsh autocompletion (domain completer) po/POTFILES.in | 1 + tests/virshtest.c | 268 +++++++++++++ tools/Makefile.am | 3 +- tools/virsh-completer.c | 355 +++++++++++++++++ tools/virsh-completer.h | 85 +++++ tools/virsh-domain-monitor.c | 287 +------------- tools/virsh-domain.c | 72 ++++ tools/virsh-snapshot.c | 11 + tools/virsh.c | 880 +++++++++++++++++++++++++++++++++++++------ tools/virsh.h | 20 + 10 files changed, 1582 insertions(+), 400 deletions(-) create mode 100644 tools/virsh-completer.c create mode 100644 tools/virsh-completer.h -- 1.8.3.2

[libvirt] [PATCH 0/4] Enable spapr-pci-vfio-host-bridge controllers for VFIO passthrough support
by Shivaprasad G Bhat 17 Oct '14

17 Oct '14

The following series of patches enable spapr-pci-vfio-host-bridge controllers on PPC64-pseries machine which is required for supporting host device passthrough using VFIO. There were some initial enablement work on the same at http://www.redhat.com/archives/libvir-list/2013-September/msg00838.html. The testing revealed contrasting observations and the current patch series solve the same. Unlike other architectures, on pseries(ppc64) the vfio host devices(will refer as hostdevs here on) cannot be assigned to the default emulated pci-host- bus controller(like the default pci.0). On pseries, the hostdevs goto spapr-pci-vfio-host-bridge. The hostdevs belonging to the same iommu group share the same spapr-pci-vfio-host-bridge. Henceforth, new spapr-pci-host-bridge needs to be added for every hostdev belonging to any new iommu group. The hostdevs appear in new pci domain inside the guest. The spapr-pci-vfio-host-bridge is a generic bridge and it can host both pci and pci-e host devices. The model pci-root is chosen for this controller just for convenience. The patch series take care to add the new controller. Each new controller creates up a new pci domain in the guest. Every hostdev get their pci address in the relavent domain. Tha patch series take care of device addressing in passthrough hostdevs, SR-IOV interfaces and network interface from SRIOV virtual function pools. --- Shivaprasad G Bhat (4): qemu: Add SPAPR_VFIO_HOST_BRIDGE capability for PPC platform qemu: parse and add spapr-vfio-pci controller into domain qemu: assign addresses for spapr vfio hostdevices and generate cli qemu: add test case for spapr-pci-vfio-host-bridge docs/schemas/domaincommon.rng | 28 ++ src/bhyve/bhyve_domain.c | 2 src/conf/domain_addr.c | 8 - src/conf/domain_addr.h | 1 src/conf/domain_conf.c | 149 ++++++++++- src/conf/domain_conf.h | 19 + src/libvirt_private.syms | 2 src/qemu/qemu_capabilities.c | 2 src/qemu/qemu_capabilities.h | 1 src/qemu/qemu_command.c | 279 +++++++++++++++++++- src/qemu/qemu_command.h | 17 + src/qemu/qemu_domain.c | 12 - src/qemu/qemu_driver.c | 6 tests/qemuhotplugtest.c | 2 .../qemuxml2argv-hostdev-spapr-vfio.args | 16 + .../qemuxml2argv-hostdev-spapr-vfio.xml | 76 +++++ tests/qemuxml2argvtest.c | 8 + 17 files changed, 591 insertions(+), 37 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hostdev-spapr-vfio.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-hostdev-spapr-vfio.xml -- Signature

[libvirt] Tunneled migration failures
by Gary Hook 17 Oct '14

17 Oct '14

So here¹s the thing: I have an environment running without tunneling. I can move a modestly sized (3.2GB disk space, 2GB RAM) VM back and forth between two systems all day long, using peer-peer migration, with these flags set: VIR_MIGRATE_UNDEFINE_SOURCE VIR_MIGRATE_PEER2PEER VIR_MIGRATE_PERSIST_DEST VIR_MIGRATE_NON_SHARED_INC By invoking libvirt_domain_migrate_to_uri2() in libvirt-php via apache. We are not using shared storage, but as stated, the function invocations and XML appear to be correct insofar as non-tunneled migrations are successful. As soon as I enable tunneling by adding the VIR_MIGRATE_TUNNELLED to the above options, the migration fails with this debug message: qemuMigrationUpdateJobStatus:1788 : operation failed: migration job: unexpectedly failed Not very helpful. This is with no other changes to the invoking code. I have been _trying_ to track down the source of the failure, and in so doing I have increased the arbitrary timeout value in qemu_domain.c from 30 to 100 seconds. The copy of the disk is successful; nabbing a copy and booting it in an alternate VM works just fine, so I have every reason to believe that the disk is being migrated properly. That said, what I need is to understand how to trace the monitoring thread over on the destination, to understand where and why it is returning an error to the source host. The debug output is silent on finding and error and sending it back to the source system. I¹ve been instrumenting the calls in src/qemu, but haven¹t located the right code. A pointer to where I should be looking would be helpful. I can provide much more detail from tracing (that I have had to add to the code) on the source side, but the destination side log entries get to virStreamFinish() and then the thread exits while the sender gets an error back. Ostensibly from another thread. The migration gets cancelled for no obvious reason, from no obvious source. Here¹s the kicker: this exact same scenario using a smaller VM (1.5GB disk, 2GB RAM) succeeds. The issue appears to be related to VM size and timeout values? Again, if a developer could provide a pointer to how I might trace the monitoring thread on the destination side, that¹d be great. Thanks in advance. Gary

[libvirt] [PATCH 0/5] libxl: user-specified domain config improvements
by Jim Fehlig 16 Oct '14

16 Oct '14

This is essentially a V2 of Stefan's patch to add support for user-specified video device in the libxl driver. https://www.redhat.com/archives/libvir-list/2014-September/msg01157.html It goes a bit further and adds support for user-specfied <emulator>, which was trivial to add after introducing libxlDomainGetEmulatorType in patch 3. To ease review, the series has been split up as follows: - Missed keymap config from commit 4dfc34c3 split out to patch 1 - Patch 2 added to defer setting default vram value to the Xen drivers - Patch 3 added to detect old qemu-dm vs qemu with xen support - Patch 4 is a slightly reworked version of Stefan's patch - Patch 5 added to support user-specified <emulator> Jim Fehlig (4): libxl: Copy user-specified keymap to libxl build info struct Xen: Defer setting default vram value to Xen drivers libxl: Add function to determine device model type libxl: Support user-specified <emulator> Stefan Bader (1): libxl: Implement basic video device selection src/conf/domain_conf.c | 4 ++ src/libxl/libxl_conf.c | 124 +++++++++++++++++++++++++++++++++++++++++++++++ src/libxl/libxl_conf.h | 3 ++ src/libxl/libxl_domain.c | 22 +++++++++ src/xen/xen_driver.c | 19 ++++++++ 5 files changed, 172 insertions(+) -- 1.8.4.5

[libvirt] [docs] Couple of wiki pages with examples of live block operations
by Kashyap Chamarthy 16 Oct '14

16 Oct '14

Heya, Here are some examples of live block operations (to begin with, active blockcommit) after some testing and from discussions with Eric Blake on IRC/email: http://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit http://wiki.libvirt.org/page/Live-merge-an-entire-disk-image-chain-includin… I linked the above two pages here: http://wiki.libvirt.org/page/Main_Page#Examples_of_live_block_opertaions Will try to add more examples (like blockcopy, etc) and post them for review here. If you have comments/rewording/corrections you can provide here and I can update the wiki or you can just edit the wiki yourself. PS: I wondered breifly whether to post the plain text of the wiki content to the list but decided against it to keep the email brief :-) -- /kashyap

I am trying to track down if my issues with libvirt_lxc are down to me missing the changes in libvirt or the kernel (libvirt 1.2.9, Linux 3.16.3) that are mentioned from this thread. I am looking for either the git changes in both libvirt and linux (currently failing to find either) or if indeed these changes made it upstream? Is anyone able to point me in the right direction please? This is for the issue I have with proc remounting while using <idmap> which I believe is the problem talked about in this thread, but I could well be barking up the wrong tree. virsh # start testvm error: Failed to start domain testvm error: internal error: guest failed to start: Failed to re-mount /proc/sys on /proc/sys flags=1021: Operation not permitted Many thanks, Adrian

[libvirt] [PATCH] virsh: domain: Use global constant for XML file size limit
by Peter Krempa 14 Oct '14

14 Oct '14

Few places still used hardcoded limit for maximum XML size for commands that accept XML files. The hardcoded limits ranged from 8k to 1M. Use VSH_MAX_XML_FILE to express this limit in a unified way. This will bump the limit for the commands that used hardcoded string lengths to 10M.

[libvirt] libvirt internal snapshots incremental or not.
by Sijo Jose 13 Oct '14

13 Oct '14

Hi, Is libvirt internal snapshots are incremental or not..? Consider the example, There are 3 snapshots, created respectively snp1 first, after some changes snp2, again after some changes snp3. Question, 1.Is there any dependency that is ...snp2 depended upon snp1 and snp3 depended upon snp2 OR snp1 OR both 2.So if I remove snp2, does it makes snp3 invalid, OR can I use snp3 further. -- *Regards* *Sijo Jose*

[libvirt] [RFC PATCH] iface-unbridge: Output in-use domain list instead of removing a in-used bridge forcibly
by Lin Ma 11 Oct '14

virsh iface-unbridge directly removes the bridge even though there are guest interfaces attach to. This patch outputs in-use domain list instead of removing bridge in this case. I knew that generally virsh-*.[ch] files are self contained, But for iterating all of domains, The patch broke this rule, So I sent it as RFC to see whether the patch makes sense or if there is a better way.

[libvirt] [PowerPC Patch 0/4] Libvirt CPU enhancements for Power KVM
by Prerna Saxena 10 Oct '14

10 Oct '14

This patch series is a collection of enhancements for PowerPC CPUs on PowerKVM. Series Summary: ========== Patch 1/4 : Introduce a new architecture 'ppc64le' for libvirt. Patch 2/4 : Add libvirt support for VMs running in 'compat' mode on Power KVM. Patch 3/4 : Optimize PVR comparison for PowerPC CPUs. Patch 4/4 : Correctly model available CPUs in response to PowerPC QEMU implementation. Detail: ==== * PowerPC has traditionally been a Big-endian architecture. However, with PowerPC ISA version 2.07, it can run in Little-endian mode as well. IBM Power8 processors, compliant with ISA 2.07 allow launching VMs in little-endian mode. This is signified by 'ppc64le' architecture. Patch 1 adds this support to libvirt, to allow running VMs based on ppc64le architecture. * Patch 2-4 tweak libvirt to correctly model PowerPC CPUs based on recent PowerKVM implementation. PowerKVM permits VMs with vcpus in the following allowed modes : i) Host native mode: where the vcpu seen in the VM belongs to the same processor generation as the host. Example: A power8 host, conforming to PowerISA version 2.07, will run VMs with "power8" vcpus. ii) Binary Compatibility ("compat") mode: PowerISA allows processors to run VMs in binary compatibility ("compat") mode supporting an older version of ISA. As an example: In compatibility mode, a POWER8 host can run a "power7" VM conforming to PowerISA v2.06, while a POWER7 host can run a "power6" VM, conforming to power ISA v2.05. QEMU has recently added support to explicitly denote a VM running in compatibility mode through commits 6d9412ea & 8dfa3a5e85. Henceforth, VMs of type (i) will be invoked with the QEMU invocation "-cpu host", while VMs of type (ii) will be invoked using "-cpu host, compat=power6". Now, an explicit cpu selection using "-cpu POWER6" is moot, and the recommended practice is to use the matching compat mode, if the requested cpu type differs from the host. Patches 2-4 address various aspects of this change. * Patch 2 : Adds support for generating the correct command line for QEMU. New xml semantics are introduced to signify this type. * Patch 3 : PowerKVM vCPUs differ uniquely across generations ( such as power6, power7, power8). Each generation signifies a new PowerISA version that exhibits features unique to that generation. The higher order 16 bits of PVR denote the processor generation and the lower order 16 bits denote the cpu chip (sub)version. For all practical purposes of launching a VM, we care about the generation the vCPU will belong to, and not specifically the chip version. In fact, PowerKVM does not seek out specification of a unique chip version(such as POWER7_v2.3) for running a vCPU. This patch updates the libvirt PVR check to reflect this relationship. * Patch 4: As specified in QEMU commit 8dfa3a5e85, the supported modes for a "compat" CPU are power6/power7/power8. This patch amends cpu_map.xml to understand these modes. PPC64 CPU Test cases are also updated accordingly. This patch also includes a test case for compat mode, introduced in patch 2. Changelog: ====== Patch 1/4 : This is v1. Patch 2/4 : Rebased initial patch https://www.redhat.com/archives/libvir-list/2014-June/msg01338.html Patch 3/4, 4/4 : This is v2, addressing response https://www.redhat.com/archives/libvir-list/2014-August/msg00859.html -- Prerna Saxena Linux Technology Centre, IBM Systems and Technology Lab, Bangalore, India

[libvirt] [PATCH] Fix leftover typo '&' -> '&&'
by Martin Kletzander 09 Oct '14

09 Oct '14

The actual origin of this so called typo are two commits. The first one was commit 72f8a7f that came up with the following condition: if ((i == 8) & (flags & VIR_QEMU_PROCESS_KILL_FORCE)) Fortunately this succeeded thanks to bool being (int)1 and VIR_QEMU_PROCESS_KILL_FORCE having the value of 1 << 0. The check was then moved and altered in 8fd38231179c394f07d8a26bcbf3a0faa5eeaf24 to current state: if ((i == 50) & force) that will work again (both sides of '&' being booleans), but since this was missed so many times, it may pose a problem in the future in case it gets copy-pasted again.

[libvirt] [Question] capabilities.pidfile is left behind while starting and stopping libvirtd repeatly
by Wang Yufei 09 Oct '14

09 Oct '14

Hi, all I started and stopped libvirtd service repeatly with high frequency(1 per second), and found that the file capabilities.pidfile is left behind, as well as a qemu process. If I then restart libvirtd, qemu-kvm will fail to start as it's unable to flock capabilities.pidfile's fd. Steps to reproduce the problem: 1. start libvirtd service per second with a shell script. 2. meanwhile, stop libvirtd service per second with another shell script. 3. then, a process qemu is left behind: /usr/bin/qemu-kvm -S -no-user-config -nodefaults -nographic -M none -qmp unix:/var/lib/libvirt/qemu/capabilities.monitor.sock,server,nowait -pidfile /var/lib/libvirt/qemu/capabilities.pidfile -daemonize 4. file /var/lib/libvirt/qemu/capabilities.pidfile is left behind 5. start libvirtd again, the process qemu-kvm fails to start. The cause of the problem: This file is generated by qemu, and deleted by libvirtd. If libvirtd got killed before it removes the pidfile, it would be left behind then. Question: Would it be fine if I kill qemu-kvm process and unlink capabilities.pidfile, just before virQEMUCapsInitQMP runs this qemu-kvm process? -- Best Regards Wang Yufei

[libvirt] [PATCH v2] hotplug: Fix libvirtd crash on qemu-attached guest
by John Ferlan 08 Oct '14

08 Oct '14

https://bugzilla.redhat.com/show_bug.cgi?id=1141621 The crash in this case was because the qemu-attach code did not create aliases for qemu cli args. When the detach-interface code was called it assumed aliases were set resulting in a core when dereferencing the still NULL alias. Adding a call to qemuAssignDeviceAliases() resolves the path for qemu-attach; however, to prevent future issues an additional check for a NULL value is made and an error provided in the deatch path. Add some more verbiage to the virsh man page.

[libvirt] [PATCH v3 0/2] network: Add network bandwidth for ethernet type interfaces
by Anirban Chakraborty 08 Oct '14

08 Oct '14

V3: Addressed issues pointed out in V2 Split into two patches V2: Addressed comments raised in review of V1. Consolidate calls to virNetDevBandwidthSet. Clear bandwidth settings when the interface is detached or domain destroyed. V1: Ethernet interfaces in libvirt currently do not support bandwidth setting. For example, following xml file for an interface will not apply these settings to corresponding qdiscs.

[libvirt] [PATCH] security_selinux: Don't relabel /dev/net/tun
by Michal Privoznik 08 Oct '14

08 Oct '14

https://bugzilla.redhat.com/show_bug.cgi?id=1147057 The code for relabelling the TAP FD is there due to a race. When libvirt creates a /dev/tapN device it's labeled as 'system_u:object_r:device_t:s0' by default. Later, when udev/systemd reacts to this device, it's relabelled to the expected label 'system_u:object_r:tun_tap_device_t:s0'. Hence, we have a code that relabels the device, to cut the race down. For more info see ae368ebfcc4. But the problem is, the relabel function is called on all TUN/TAP devices. Yes, on /dev/net/tun too. This is however a special kind of device - other processes uses it too. We shouldn't touch it's label then. Ideally, there would an API in SELinux that would label just the passed FD and not the underlying path. That way, we wouldn't need to care as we would be not labeling /dev/net/tun but the FD passed to the domain. Unfortunately, there's no such API so we have to workaround until then.

[libvirt] [PATCH v2] qemu: Pass file descriptor when using TPM passthrough
by Stefan Berger 08 Oct '14

08 Oct '14

From: Stefan Berger <stefanb(a)linux.vnet.ibm.com> Pass the TPM file descriptor to QEMU via command line. Instead of passing /dev/tpm0 we now pass /dev/fdset/10 and the additional parameters -add-fd set=10,fd=20. This addresses the use case when QEMU is started with non-root privileges and QEMU cannot open /dev/tpm0 for example. One problem is that for the passing of the file descriptor set to work, virCommandReorderFDs must not be called on the virCommand. This is prevented by setting a flag in the virCommandPassFDGetFDIndex that is checked to be clear when virCommandReorderFDs is run.

[libvirt] [PATCH 0/2] esx: Add libcurl based stream driver and implement virDomainScreenshot
by Matthias Bolte 07 Oct '14

07 Oct '14

I had the code in these two patches bascially sitting around since 2012, yes 2012! But I never managed to get the code properly split into patches and touched up good enough to post it here. This was also hindered by the fact that I had no ESX test system at hand for the last year or so. Dawid Zamirski posted some patches [1] to implement virDomainScreenshot for ESX. So I finally managed to set up some ESX test system again this weekend and get my old code dusted up. His implementation has two disadvantages, namely storing the screenshot to a temporary file before feeding it to a stream and the method of creating the screenshot itself is availalbe since ESX 4.0 only. My implementation direcly feeds the screenshot data to a stream and screenshot creation uses a method available since ESX 2.5.

[libvirt] [RFC PATCH] include: make it easier to probe enum growth
by Eric Blake 07 Oct '14

07 Oct '14

https://bugzilla.redhat.com/show_bug.cgi?id=1147639 is an example of a downstream distro's dilemma - when backporting a feature that is implemented in an ABI-compatible manner (no .so bump was required) but where the feature involves new bits to be defined in a flags variable, how does one write code to reliably detect that those bits have been backported? The solution presented here is a common idiom used in a number of other header files (for example, glibc's /usr/include/langinfo.h does it for ABDAY_1 and friends); by adding a self-referential preprocessor macro, client code can easily do: | switch (state) { | #ifdef VIR_DOMAIN_PMSUSPENDED | case VIR_DOMAIN_PMSUSPENDED: | .... | #endif | } rather than trying to figure out which version number introduced VIR_DOMAIN_PMSUSPENDED (v.9.11), and using that with LIBVIR_CHECK_VERSION. Of course, since 1.2.10 would be the first release where this practice is reliable, we will still see clients that target earlier libvirt doing: | switch (state) { | #if LIBVIR_CHECK_VERSION(0, 9, 11) || defined(VIR_DOMAIN_PMSUSPENDED) | case VIR_DOMAIN_PMSUSPENDED: | .... | #endif | } but that is still more maintainable. * include/libvirt/libvirt.h.in (virDomainState): Expose #defines matching each enum value. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- This patch is an RFC because I want confirmation that it is worth doing. Obviously, if it is desirable, there will be a LOT more addition of #define throughout the file, but as that is mostly busy-work, I want to get the idea approved first. include/libvirt/libvirt.h.in | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index c910b31..0baea53 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -116,13 +116,28 @@ typedef virDomain *virDomainPtr; * A domain may be in different states at a given point in time */ typedef enum { +#define VIR_DOMAIN_NOSTATE VIR_DOMAIN_NOSTATE VIR_DOMAIN_NOSTATE = 0, /* no state */ + +#define VIR_DOMAIN_RUNNING VIR_DOMAIN_RUNNING VIR_DOMAIN_RUNNING = 1, /* the domain is running */ + +#define VIR_DOMAIN_BLOCKED VIR_DOMAIN_BLOCKED VIR_DOMAIN_BLOCKED = 2, /* the domain is blocked on resource */ + +#define VIR_DOMAIN_PAUSED VIR_DOMAIN_PAUSED VIR_DOMAIN_PAUSED = 3, /* the domain is paused by user */ + +#define VIR_DOMAIN_SHUTDOWN VIR_DOMAIN_SHUTDOWN VIR_DOMAIN_SHUTDOWN= 4, /* the domain is being shut down */ + +#define VIR_DOMAIN_SHUTOFF VIR_DOMAIN_SHUTOFF VIR_DOMAIN_SHUTOFF = 5, /* the domain is shut off */ + +#define VIR_DOMAIN_CRASHED VIR_DOMAIN_CRASHED VIR_DOMAIN_CRASHED = 6, /* the domain is crashed */ + +#define VIR_DOMAIN_PMSUSPENDED VIR_DOMAIN_PMSUSPENDED VIR_DOMAIN_PMSUSPENDED = 7, /* the domain is suspended by guest power management */ -- 1.9.3

[libvirt] [PATCH] Fix build-time pkg-config files in VPATH
by Jiri Denemark 07 Oct '14

07 Oct '14

The pkg-config files in src/ make it pretty easy to build language bindings against an uninstalled libvirt, however, they don't work with VPATH builds. The reason is that all *-api.xml files are generated in source rather than build directory.

[libvirt] [libvirt-python PATCH] sanitytest: define long for python version >= 3
by Martin Kletzander 07 Oct '14

07 Oct '14

Commit c58c7f362aab37e4961407c2efc8a74925ed9c37 fixed 32-bit python build but broke build with python3 due to the lack of 'long' in the newer version of python. This patch aims to fix it with a simple string comparison of sys.version and '3'.

[libvirt] [libvirt-python PATCH] sanitytest: count with the fact that large enums can be long
by Martin Kletzander 07 Oct '14

07 Oct '14

On 32-bit systems, one new flag that has the value of 1 << 31, namely VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS, fails to fit into an 'int' on python and is therefore of type 'long'. Fix sanitytest to count with such fact in order to avoid build failures on 32-bit systems.
