@miguelaferreira Thanks. I guess returning `null` is done in many of the
Investigators right now, but would be great to improve it. If we at least could
make it the same in 4.4 like in master that'd be great because that works
(https://github.com/apache/cloudstack/blob/master/plugins/hypervisors/hyperv/src/com/cloud/ha/HypervInvestigator.java)
and that throws `throw new UnknownVM();`
The `OVM3` Investigator also seems smarter
(https://github.com/apache/cloudstack/blob/master/plugins/hypervisors/ovm3/src/main/java/com/cloud/ha/Ovm3Investigator.java).
I could live with a quick hotfix for `4.4` that I can deploy soon, and then
improving this whole thing in `master`. Not sure what is possible right now.
We'll discuss tomorrow :-)
