I have a WinXP VM that I prefer to run off a firewire disk so my MacOS is not fighting the VM for the disk. I keep a copy of this VM on my local drive just in case I need it and don't have the firewire drive with me. They are listed as separate machines in the Virtual Machine List, which is fine, but does anyone have any thoughts on how to synchronize any changes made on one VM to the other? I never have them both running at the same time and I usually shut down the VM when done as it takes about the same amount of time to reboot as to resume. So far I've been using rsync in a script file to copy from one to another, but that seems inefficient. Anyone have any ideas?
