+++   bug 1487728 +++

Description of problem:

If 'run_on_vds' in the vm_dynamic table in the RHV database contains a host id, but the VM is actually down, the engine will report the following;

- engine.log;

They are not normal either way, but the host was responding, actually.
We should deal with the exception more gracefully, no matter how it happened (it may be restore from a backup)

Comment 6 rhev-integ 2017-09-08 06:20:46 UTC
do we want also a 4.1 backport of https://gerrit.ovirt.org/#/c/81560/ ?
