There few ways I could get there:
1. Testing some code and creating vdsm and later dropping db and
reinstalling the host with "new db"
2. Vms provisioned manually.

At this time it seems to be option #2 and I see:

[root at f20 ~]# virsh -r list --all
 Id    Name                           State
----------------------------------------------------
 -     centos7                        shut off
 -     rhel7.0-dev                    shut off

which are machines where I test el7 compatibility of my changes (I use
fedora25 on bare metal).

I see the failure every time I run the engine now since I sent the
email to this thread. It started
to occur recently event though I have those vms there for really long time.
