More details on the subject:
I suppose it is a nested KVM issue because it raised after I enabled the
nested KVM feature. Without it, anyway, the second level VMs are unusable
in terms of performance.
I am using CentOS 7 with:
on both the baremetal and the compute VM.
The only workaround now is to shutdown the compute VM and start it back
from baremetal with virsh start.
A simple restart of the compute node doesn't help. It looks like the
qemu-kvm process corresponding to the compute VM is the problem.
