[libvirt] [PATCH] lib: Avoid double free when passing FDs with virCommandPassFD()
by Michal Privoznik 17 May '19

17 May '19

If an FD is passed into a child using: virCommandPassFD(cmd, fd, VIR_COMMAND_PASS_FD_CLOSE_PARENT); then the parent should refrain from touching @fd thereafter. This is even documented in virCommandPassFD() comment. The reason is that either at virCommandRun()/virCommandRunAsync() or virCommandFree() time the @fd will be closed. Closing it earlier, e.g. right after virCommandPassFD() call might result in undesired results. Another thread might open a file and receive the same FD which is then unexpectedly closed by virCommandFree() or virCommandRun().

[libvirt] [PATCH] qemu: Do not override config XML in case of snapshot revert
by Maxiwell S. Garcia 15 May '19

15 May '19

Snapshot create operation saves the live XML and uses it to replace the domain definition in case of revert. But the VM config XML is not saved and the revert operation does not address this issue. This commit prevents the config XML from being overridden by snapshot definition. An active domain stores both current and new definitions. The current definition (vm->def) stores the live XML and the new definition (vm->newDef) stores the config XML. In an inactive domain, only the config XML is persistent, and it's saved in vm->def. The revert operation uses the virDomainObjAssignDef() to set the snapshot definition in vm->newDef, if domain is active, or in vm->def otherwise. But before that, it saves the old value to return to caller. This return is used here to restore the config XML after all snapshot startup process finish. Signed-off-by: Maxiwell S.

[libvirt] [PATCH 0/2] introduction of version attribute for VFIO live migration
by Yan Zhao 15 May '19

15 May '19

This patchset introduces a version attribute under sysfs of VFIO Mediated devices. This version attribute is used by user space software like libvirt to determine whether two mdev devices are compatible for live migration before starting live migration. Patch 1 defines version attribute as mandatory for VFIO live migration. It means if version attribute is missing or it returns errno, the corresponding mdev device is regarded as not supporting live migration. samples for vfio-mdev are modified to demonstrate it. Patch 2 uses GVT as an example to show how to expose version attribute and check device compatibility in vendor driver.

[libvirt] [PATCH 0/2] Avoid issues due to qemu dropping osxsave and ospke
by Christian Ehrhardt 15 May '19

15 May '19

Hi, this series tries to address a drop of commandline options by qemu in regard to osxsave [1] and ospke [2]. This was already discussed in [3] late last year but got forgotten afterwards. The Ubuntu bug is at [4] and an older Fedora bug is at [5]. TL;DR: - osxsave/ospke features were never really configurable - KVM never returned the bits on GET_SUPPORTED_CPUID - very rare to be seen in the wild - avoid issues with newer qemu and old/odd XMLs to be sure Details: I checked various use cases from virt-install to openstack and some in between. The only cases I found that would define osxsave/ospke is virt-install pior to version 2.0 and even there only when used with --cpu=host-model or --cpu=host-copy. If you ever really enabled the feature you'd have got: error: the CPU is incompatible with host CPU: Host CPU does not provide required features: ospke The problem lies in domain XMLs that explicitly disable it. That would be <feature policy='disable' name='osxsave'/> But due to almost (or actually none) no host exposing this the following also triggers: <feature policy='optional' name='ospke'/> This will make libvirt add it to the qemu commandline like: -cpu ...,osxsave=off,ospke=off And that will crash when qemu starts with: error: internal error: process exited while connecting to monitor: 2019-04-25T12:12:01.698646Z qemu-system-x86_64: can't apply global core2duo-x86_64-cpu.osxsave=off: Property '.osxsave' not found There are much more long term discussions about demoting and dropping qemu features and I'd like to avoid those discussions being mixed. The reason to drop it more or less without notice was that it never did anything to begin with. Due to that our solution might in a similar fashion be more trivial - just stop defining those two features to qemu commandline.

[libvirt] [PATCH RFC] network: Delay creating private chains until starting network
by Jim Fehlig 13 May '19

13 May '19

Automated performance tests found that network-centric workloads suffered a 20 percent decrease when the host libvirt was updated from 5.0.0 to 5.1.0. On the test hosts libvirtd is enabled to start at boot and the "default" network is defined, but it is not set to autostart. libvirt 5.1.0 introduced private firewall chains with commit 5f1e6a7d. The chains are created at libvirtd start, which triggers loading the conntrack kernel module. Subsequent tracking and processing of connections resulted in the performance hit. Prior to commit 5f1e6a7d the conntrack module would not be loaded until starting a network, when libvirt added rules to the builtin chains. Restore the behavior of previous libvirt versions by delaying the creation of private chains until the first network is started. Signed-off-by: Jim Fehlig <jfehlig(a)suse.com> --- I briefly discussed this issue with Daniel on IRC and just now finding time to bring it to the list for broader discussion.

[libvirt] [PATCH 0/5] tests: Refresh/add capabilities for QEMU 4.0.0
by Andrea Bolognani 06 May '19

06 May '19

Now that it's officially out, we can refresh existing capabilities created from git snapshots and introduce them for the architectures where they were missing altogether. This series covers all architectures except for s390x, to which I don't have convenient access: Pino promised me he'd take care of that one in a few days. As usual for this kind of series, most patches have been snipped with extreme prejudice in order to make them small enough that they wouldn't end up in the moderation queue: the unabridged version can be found at https://github.com/andreabolognani/libvirt in the 'qemucaps-4.0.0' branch. It'd be great if we could sneak these in during the freeze so that I won't have to possibly regenerate them again after the post-release merge flood ;) Andrea Bolognani (5): tests: Refresh capabilities for QEMU 4.0.0 on x86_64 tests: Refresh capabilities for QEMU 4.0.0 on riscv32 tests: Refresh capabilities for QEMU 4.0.0 on riscv64 tests: Add capabilities for QEMU 4.0.0 on aarch64 tests: Add capabilities for QEMU 4.0.0 on ppc64 .../qemu_4.0.0.x86_64.xml | 3 +- ...v32.replies => caps_4.0.0.aarch64.replies} | 6997 ++-- .../caps_4.0.0.aarch64.xml | 310 + ...scv32.replies => caps_4.0.0.ppc64.replies} | 29886 ++++++++++------ .../qemucapabilitiesdata/caps_4.0.0.ppc64.xml | 1077 + .../caps_4.0.0.riscv32.replies | 10 +- .../caps_4.0.0.riscv32.xml | 4 +- .../caps_4.0.0.riscv64.replies | 10 +- .../caps_4.0.0.riscv64.xml | 4 +- .../caps_4.0.0.x86_64.replies | 3331 +- .../caps_4.0.0.x86_64.xml | 38 +- ...arch64-os-firmware-efi.aarch64-latest.args | 2 +- .../aarch64-virt-graphics.aarch64-latest.args | 2 +- .../aarch64-virt-headless.aarch64-latest.args | 2 +- 14 files changed, 25862 insertions(+), 15814 deletions(-) copy tests/qemucapabilitiesdata/{caps_4.0.0.riscv32.replies => caps_4.0.0.aarch64.replies} (86%) create mode 100644 tests/qemucapabilitiesdata/caps_4.0.0.aarch64.xml copy tests/qemucapabilitiesdata/{caps_4.0.0.riscv32.replies => caps_4.0.0.ppc64.replies} (71%) create mode 100644 tests/qemucapabilitiesdata/caps_4.0.0.ppc64.xml -- 2.20.1
