Comment 23 for bug 1915811

#VERIFICATION GROOVY

Using the test case described in the description, where a VM has 128 vcpus assigned, the version in -updates does not list the topology:

$ dpkg -l | grep libvirt
ii libvirt-clients 6.6.0-1ubuntu3.3 amd64 Programs for the libvirt library
ii libvirt-daemon 6.6.0-1ubuntu3.3 amd64 Virtualization daemon
ii libvirt-daemon-driver-qemu 6.6.0-1ubuntu3.3 amd64 Virtualization daemon QEMU connection driver
ii libvirt-daemon-system 6.6.0-1ubuntu3.3 amd64 Libvirt daemon configuration files
ii libvirt-daemon-system-systemd 6.6.0-1ubuntu3.3 amd64 Libvirt daemon configuration files (systemd)
ii libvirt0:amd64 6.6.0-1ubuntu3.3 amd64 library for interfacing with different virtualization systems

$ virsh capabilities | xmllint --xpath '/capabilities/host/topology' -
<topology>
      <cells num="0">
      </cells>
    </topology>

The package in -proposed fixes the issue (output shortened):

$ dpkg -l | grep libvirt
ii libvirt-clients 6.6.0-1ubuntu3.4 amd64 Programs for the libvirt library
ii libvirt-daemon 6.6.0-1ubuntu3.4 amd64 Virtualization daemon
ii libvirt-daemon-driver-qemu 6.6.0-1ubuntu3.4 amd64 Virtualization daemon QEMU connection driver
ii libvirt-daemon-system 6.6.0-1ubuntu3.4 amd64 Libvirt daemon configuration files
ii libvirt-daemon-system-systemd 6.6.0-1ubuntu3.4 amd64 Libvirt daemon configuration files (systemd)
ii libvirt0:amd64 6.6.0-1ubuntu3.4 amd64 library for interfacing with different virtualization systems
