If an instance running on openStack going down, which infrastructure
component is responsible to recover the vm from the failure by doing some
mechanism such as live migration?

If a host with multiple VMs going down, is there any openStack component to
automatically recover all of VMs from the failure?(For example
automatically start other host, and migrate all of the instances to the new

Some experts said, this type of disaster recovery must be address at
application layer(DR module on application bundled in VM), instead of
infrastructure layer?
What is your idea?
