Hi,

When deleting an oVirt host from Foreman, it first failed because Foreman/rbovirt (don't know who is responsible) doesn't wait for VM to shutdown before trying to delete it:

2016-06-16T15:47:25 [app] [W] Failed to destroy a compute ovirt-mqt (oVirt) instance test-ovirt.qt.cls.fr: Cannot remove VM. VM is running.

If I delete the host again, it is working (because now the VM is off).
So it is not a blocking issue, it is just annoying :-)
