#VERIFICATION USSURI

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 6.0.0-0ubuntu8.7~cloud0 amd64 Programs for the libvirt library
ii libvirt-daemon 6.0.0-0ubuntu8.7~cloud0 amd64 Virtualization daemon
ii libvirt-daemon-driver-qemu 6.0.0-0ubuntu8.7~cloud0 amd64 Virtualization daemon QEMU connection driver
ii libvirt-daemon-driver-storage-rbd 6.0.0-0ubuntu8.7~cloud0 amd64 Virtualization daemon RBD storage driver
ii libvirt-daemon-system 6.0.0-0ubuntu8.7~cloud0 amd64 Libvirt daemon configuration files
ii libvirt-daemon-system-systemd 6.0.0-0ubuntu8.7~cloud0 amd64 Libvirt daemon configuration files (systemd)
ii libvirt0:amd64 6.0.0-0ubuntu8.7~cloud0 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 6.0.0-0ubuntu8.8~cloud0 amd64 Programs for the libvirt library
ii libvirt-daemon 6.0.0-0ubuntu8.8~cloud0 amd64 Virtualization daemon

ii libvirt-daemon-system 6.0.0-0ubuntu8.8~cloud0 amd64 Libvirt daemon configuration files
ii libvirt-daemon-system-systemd 6.0.0-0ubuntu8.8~cloud0 amd64 Libvirt daemon configuration files (systemd)
ii libvirt0:amd64 6.0.0-0ubuntu8.8~cloud0 amd64 library for interfacing with different virtualization systems
