#VERIFICATION BIONIC
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-bin 4.0.0-1ubuntu8.17
amd64 programs for the libvirt library
ii libvirt-clients 4.0.0-1ubuntu8.17
amd64 Programs for the libvirt library
ii libvirt-daemon 4.0.0-1ubuntu8.17
amd64 Virtualization daemon
ii libvirt-daemon-driver-storage-rbd 4.0.0-1ubuntu8.17
amd64 Virtualization daemon RBD storage driver
ii libvirt-daemon-system 4.0.0-1ubuntu8.17
amd64 Libvirt daemon configuration files
ii libvirt0:amd64 4.0.0-1ubuntu8.17
amd64 library for interfacing with different virtualization systems
$ virsh capabilities | xmllint --xpath '/capabilities/host/topology' -
XPath set is empty
The package in -proposed fixes the issue (output shortened):
$ dpkg -l |grep libvirt
ii libvirt-bin 4.0.0-1ubuntu8.19
amd64 programs for the libvirt library
ii libvirt-clients 4.0.0-1ubuntu8.19
amd64 Programs for the libvirt library
ii libvirt-daemon 4.0.0-1ubuntu8.19
amd64 Virtualization daemon
ii libvirt-daemon-driver-storage-rbd 4.0.0-1ubuntu8.19
amd64 Virtualization daemon RBD storage driver
ii libvirt-daemon-system 4.0.0-1ubuntu8.19
amd64 Libvirt daemon configuration files
ii libvirt0:amd64 4.0.0-1ubuntu8.19
amd64 library for interfacing with different virtualization systems
$ virsh capabilities | xmllint --xpath '/capabilities/host/topology' -
