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 ?
