I see. I was thinking out-dated (hardware) and you're thinking cloud (vpx). :) You need to start the vpx with a nic in the management network. In CloudStack code, SSVM (Secondary Storage Virtual Machine) and CPVM (Console Proxy Virtual Machine) both have examples of this. They both have agents that connect back to CS Management server over the management network. That code is in SecondaryStorageManagerImpl.java and ConsoleProxyManagerImpl.java. --Alex
