Hi all,
I have been trying to understand if we currently have some VM HA support as
part of Liberty?

To be precise, how are host being down due to power failure handled,
specifically in terms of migrating the VMs but possibly even their
networking configs (tunnels etc).

The VM migration like XEN-HA or KVM cluster seem to require 1+1 HA, I have
read a few places about celiometer+heat templates to launch VMs for an N+1
backup scenario, but these all seem like one-off setups.

This issue seems to be very much important for legacy enterprises to move
their "pets" --- not sure if we can simply wish away that mindset!
