[one-users] Ping vms from the host without being in the same network

[Hector Sanjuan]

Well,

judging from this (http://dev.opennebula.org/issues/1691) it seems such  
option will come in 4.0. At the moment, supposing you have valuable data  
in the VM image and you cant simply kick up another instance, you would  
need to set a "save as" for vm disk, shutdown the vm, register a new VM  
with the new saved disk and 2 network ifaces and kick up the VM again.
