Alright, so let's focus on libvirt 4.4.0.
When I start the daemon, i can see some warnings related to QEMU:
warning : virQEMUCapsInit:942 : Failed to get host CPU cache info
warning : virQEMUCapsInit:949 : Failed to get host power management capabilities
Could this be the reason, or the beginning of an explanation ?
How can I dig and find what is the root cause ?
Best bet is to edit libvirtd.conf and set
log_filters="1:qemu_capabilities"
log_outputs="1:file:/var/log/libvirtd.log"
and then rm -rf /var/cache/libvirt/qemu and restart libvirtd. The log
file should tell you it is detecting qemu-system-x86_64 and probing it.
If anything fails it should be covered in the logs.

Daniel
