KubeVirt with libvirt 9.0.0: Requested operation is not valid: The tap0 interface already exists
by Vasily Ulyanov 23 Jan '23

23 Jan '23

Hi All, I am now trying to run our downstream KubeVirt build with a recent libvirt 9.0.0 and I see a problem that libvirt refuses to start a VM if it is configured to use a pre-created tap device: virError(Code=55, Domain=0, Message='Requested operation is not valid: The tap0 interface already exists') After looking at the git history I found the bellow commit [1] which explicitly forbids such a usecase. This basically breaks KubeVirt since libvirt there runs unprivileged and can only use the existing tap's. I haven't yet look deeper into the original issue linked to the commit. Just wanted to raise this here first. Perhaps someone can provide feedback on that. What about some alternative approach instead? Or maybe it was discussed already... BTW, I tested with the reverted commit and it was successful.

[PATCH] qemu_namespace: Umount the original /dev before replacing it with tmpfs
by Michal Privoznik 18 Jan '23

18 Jan '23

Our code relies on mount events propagating into the namespace we create for a domain. However, there's one caveat. In v8.8.0-rc1~8 I've tried to make us detect differences in mount tables between the namespace in which libvirtd runs and the domain namespace. This is crucial for any mounts that happen after the domain was started (for instance new hugetlbfs can be mounted on say /dev/hugepages1G). Therefore, we take a look into /proc/$(pgrep qemu)/mounts to see what filesystems are mounted under /dev. Now, since we don't umount the original /dev, just mount a tmpfs over it, we get all the events (e.g. aforementioned hugetlbfs mount on /dev/hugepages1G), but we are not really able to access it because of the tmpfs that's placed on top. This then confuses our algorithm for detecting which filesystems are mounted (the algorithm is implemented in qemuDomainGetPreservedMounts()). To break the link between host's and guest's /dev we just need to umount() the original /dev in the namespace. Just before our artificially created tmpfs is moved into its place.

[PATCH] qemu: Provide virDomainGetCPUStats() implementation for session connection
by Michal Privoznik 17 Jan '23

17 Jan '23

We have virDomainGetCPUStats() API which offers querying statistics on host CPU usage by given guest. And it works in two modes: getting overall stats (@start_cpu == -1, @ncpus == 1) or getting per host CPU usage. For the QEMU driver it is implemented by looking into values stored in corresponding cpuacct CGroup controller. Well, this works for system instances, where libvirt has permissions to create CGroups and place QEMU process into them. But it does not fly for session connection, where no CGroups are set up. Fortunately, we can do something similar to v8.8.0-rc1~95 and use virProcessGetStatInfo() to fill the overall stats. Unfortunately, I haven't found any source of per host CPU usage, so we just continue throwing an error in that case.

[libvirt PATCH] rpm: convert license to SPDX format
by Daniel P. Berrangé 16 Jan '23

16 Jan '23

Note that with the introduction of SPDX, Fedora no longer wants maintainers to do effective license analysis, hence we no list all the licenses that are applicable to the binary package contents https://docs.fedoraproject.org/en-US/legal/license-field/#_no_effective_lic… Note, we can still omit licenses that are only applicable to the build system.

[PATCH v1 0/4] Introduce active disk internal snapshot support
by Or Ozeri 16 Jan '23

16 Jan '23

Internal disk snapshots are currently only supported on non-active VMs. This patch series extends this support for active VMs running with qemu. This implementation for the qemu driver works even when there are other disks which ask for external snapshot. Thus we remove the restriction disallowing mixing of internal and external disk snapshots for active VMs. Note that mixing is still disallowed for non-active VMs, as it require a bit more work in a different area of the code. Additionally we add a new attribute to allow the user specifying a unique snapshot name for each internal disk snapshot. In case this optional attribute is not specified, snapshot name will be taken from the domain snapshot name, as it is currently done today.
