Currently, the XenServer builder has some quirks when compared with other Packer builders.
The builder currently only works remotely.
The installer is expected to shut down the VM to indicate that it has completed. This is in contrast to other builders, which instead detect completion by a successful SSH connection. The reason for this difference is that currently the builder has no way of knowing what the IP address of the VM is without starting it on the HIMN.
