Just wanted to comment on how fast virtual machines run on Windows 7 with Virtual PC Beta and the Integration Features enabled. It is so awesomely fast! Its like Night and Day on a Vista Virtual PC. If you build one, run Vista, then enable the features, its like 10x faster.
I can't believe they go Aero working as well on a Windows 7 guest machine, when you are basically using a Remote Desktop Connection. Good Job MS!!!
Good job on the USB device sharing too!
My only gripe is that the network is soooo slow that it seriouly takes 10 min to transfer like 5MB. I am sure it will be worked out, but if I try to pull files from my Host machine, to the guest using the network adapter, it takes forever. So slow that the speed doesn't even register. It just finishes after about 10 minutes. No biggie though with the shared usb, I just plug in a pen drive and transfer them that way.
I am running a host machine of 7600 with guest machines of Windows XP SP3, Vista SP2 and a guest 7264.
