[Openstack] VM High Availability and Floating IP

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
