This bug was fixed in the package libvirt - 11.6.0-1ubuntu8
---------------
libvirt (11.6.0-1ubuntu8) resolute; urgency=medium
* cpu_map: fix vmx-* MSR features (LP: #2083293)
- d/p/u/lp2083293-cpu_map-update-vmx-features.patch
* Enable MSR kernel module load (LP: #2106791)
In recent CPUs, some CPU features detection is done by reading
Model Specific Registers (MSR). To do that, libvirt needs the
msr kernel module to be loaded.
- d/p/d/x86-install-modules-load.d-file-to-load-msr-module.patch
- debian/libvirt-common.install.in : install msr.conf file
- debian/libvirt-common.postinst.in : trigger the module load
