I posted here how easy it was to get Virtual PC running on Vista. I figured it was a great way to tryout Vista (my office/email/messaging desktop) while still being productive with VMs containing specific development environments. However, after about a week of use, I've decided I'm better off booting into XP to run VMs. I've been experiencing “lockups” of up to 1 minute or more which make effective work impossible. For example, clicking down through directories on the C:\ drive and suddenly Explorer hangs for a while. Sometimes, I'll see the network activity icon going, other times not. If anybody has tips to share, please do!!
My host machine is a Dell Inspiron 6000 760 M (2.0 Ghz) with 2.0 Gb of RAM. The VMs are running from a USB 2.0 attached 5600 RPM drive - I know, 7200 would be better. The images are all VPC 2004 SP1 with up-to-date VM additions updated. The kicker is the same image runs well when I boot into XP and run them there. Given everything identical except the host OS I can only “blame” Vista Beta 2 as the culprit.
