##### SUMMARY
<!-- Explain the problem/feature briefly -->
CloudStack does not allow to migrate hosts from clusters. This Issue raises
the feature idea of migrating hosts between clusters.
In KVM at least this is quite easy to be done. Basically, it can be done by
changing the agent.properties and updating a few tables in the DB.
At first, I would propose creating such an API command only for KVM. As far
as I know, `XenServer` & `VMware` aren't as simple. Quite a long time since I
played with Xen or VMware, so I am not raising them here. But anyone interested
in discussing raising it. feel free.
The idea is that such a host should be placed into maintenance, making sure
that no VMs will be running.
If the host is in Maintenance, then the API command would run the needed
changes in order to have the host available at other cluster.
This would require Admins to ensure that the shared storage pool is
available at the zone-wide level.
