Hi, I'm wondering if it is possible to share a virtual machine between a mac and windows hosts? I guess it must be possible to export from one platform to the other, but I'd need to swap between the hosts on a daily basis with the VM on an external hard drive. If anyone has had any experience of this I'd love to hear if this is possible, and if so, if there were any gotchas? Thanks, Chris --- Mac host = Lion / Parallels 6, but happy to upgrade Win host = win7 need to purchase Parallels Guest = win7
