> Storage motion of vm across clusters/xenserver-pools fails
> in a clustered management server setup. In xen storage motion we have to send
> a migrate_receive command to the destination host, followed by migrate_send
> command to the source host. The sr and network detials of the destination
> host have to be passed in migrate_send command on the source. While migrating
> across clusters the source and destination resources are seperate objects. To
> pass this information across resources we have to send seperate migrate with
> storage receive and send commands to the resource. In a clustered ms setup
> these commands may have to be forwarded to another ms as the resource may be
> owned by it. The serilization of the command and answer objects fails in such
> case as it doesn't understand the xapi sr and network objects.
> The following JSON conversion error was recorded in management-server2.log.
