I believe it's the same user, but there are two issues reported on ask.openstack.org:
https://ask.openstack.org/en/question/112521/how-to-launch-a-vm-that-use-devvda-and-busvirtio-using-nova/
https://ask.openstack.org/en/question/112488/libvirt-not-allocating-cpu-and-disk-to-vms-after-the-os-update/
It seems to be related to libvirt updates, but it's not resolved yet.
