syncing contents of virtual machines

I usually sync two computers (mac and linux) using rsync so that I can work on either machine. Is it also possible to sync virtual machines (running Windows XP, sp开发者_Go百科ecifically) on both systems that have been created by VirtualBox? Probably not...?

You can probably do it with all kinds of routing rules and port forwarding, but what about having each VM use a shared folder that you are rsyncing? This way you can rsync through hosts as you normally do and the VMs will pick up and make changes since the folder is shared between host and guest.

You can try putting VM on Dropbox as well.. http://forums.dropbox.com/topic.php?id=6520
