Do you have a way to check if this server is up? If so... The start action of VirtualDomain won't exit until the monitor action returns success. And there's a parameter called monitor_scripts (see the meta-data). Note that these programs (scripts) are run at the supervisor host and not in the guest. It's all a bit involved, but should be doable.
