With OSP13 ospd installation of 1controller 1compute 1ceph,
plenty of tempest tests fail due to being unable to spawn vm in overcloud.

So far consistent issue.
Looks that libvirt/qemu fails to spawn the vm, though reason for that is unclear to me.

nova-scheduler.log lines related to uuid of one of vms which failed:

also attaching whole /var/log/messages from compute-0 node, few notable things there:
