Is there a way I can further debug this?
Setting debug to "true" didn't show a reason why VMs are spreading and
which filter is used every time which will make VMs spread.
In addition I think that I 've read somewhere that placement does this
(stack VMs) by default but have not seen that behavior at all...
Any ideas appreciated...
P.S: Added the "scheduler" tag to catch more attention from the correct
