I moved servers within our location at work today. While it was a pretty physical workout (servers containing many drives & redundant power supplies make for some heavy lifting), it was much more mentally draining.
It's amazing how long & panicked the wait between powering up a RAID array is, and the time it states it's fully functional is. All went well, and Hyper-V is right where it belongs. I could actually feel my heart beating in my chest as I watched the lights cycle... finally rendering their blue verdict.
My only complaint so far with Hyper-V in Windows 2008 is the weak support of P2V (that is, Physical to Virtual conversion). I've got some pretty dated win 2000 servers that I'd like to retire, but it seems I need to create the VM's the old-fashioned way, through windows install disks, and manually copying the data over. The only other issue so far I've found with windows 2008 is the difficulty in Apple machines getting an IPv4 address through DHCP on a Windows 2008 server. Hopefully I'll find a way around that, since I can force people to use Windows.
