I’ve recently had the inclination to give Hyper-V a go now that it wasn’t only a release candidate. After a brief setup and install, I was impressed with the responsiveness of the MMC snapin. Compared to VMWare’s Infratructure Client (VIC) it is a huge difference. VIC has on often crashed, hung, or otherwise frustrated me. Performance wise, Hyper-V seems to be about the same as ESXi for us. The differences, of course, are that I don’t have to store files on VMFS and I have complete control over the server, rather than only through VIC. It is rather refreshing!
I am rather looking forward to Windows Server 2008 R2, because Hyper-V promises new features, including live migration. VMWare is in trouble if that works well!
