Description Joop van de Wege 2014-04-04 14:41:59 UTC 
As per request on the ML.
For negative affinity it would be fine if it made sure that it worked too :-)
(more difficult due to corner cases but very nice to have too)

Hi Joop, 

You've created a positive enforcing affinity group -> means that VMs should stay on the same host, no migration allowed while more than one VM is up.
What you're requesting is a useful RFE, some-kind of a 'follow me' positive affinity group.
I'm +1 on that  :-)  can you please open a formal request/RFE for it?

Thanks, 
Gilad.

Closing old bugs. If this issue is still relevant/important in current version, please re-open the bug.

Just tested it in 3.5.1 and if you make a positive affinity group with two VMs then VM-b won't follow VM-a when VM-a is migrated to a different host.
Starting VM-b after VM-a works, both end up on the same host but the above case needs to be implemented.
