Yeah it's the same problem as bug 1820892, libvirt-python is installed
on py27 rather than py36:
http://logs.openstack.org/45/638645/11/gate/neutron-grenade-dvr-
multinode/4064577/logs/pip2-freeze.txt.gz
libvirt-python==4.6.0

Title:
nova-compute don't start in grenade job due to missing libvirt module
Status in OpenStack Compute (nova):
New
Bug description:
I found that sometimes grenade jobs are failing and reason of that failure is
that nova-compute is not started.
