[Alex Glikson <GLIKSON@xxxxxxxxxx>]

We are working on a patch that would enable such capability within 
OpenStack Nova. 
It is a bit more complex than what you suggested. In a nutshell, one would 
need to do the following:
- re-create the VM on the destination host
- re-attach volumes/IPs
- update DB
- make sure that if/when the original host recovers, it does not cause 
corruption of the instance file on shared storage (e.g., by removing the 
corresponding VM from the original host on startup)

Regards,
Alex

But i don't see any part (except the future plans) talking about HA at 
instance level, that seems more to an application level
