So far Hyper-V has put up enough resistance to make me wish I’d plumped for ESXi. It isn’t a bad product, but I can’t get over its lack of integrated management. I made the mistake of joining it to our domain whilst it was in the workshop and then trying to manage it on the clients site. It flatly refused.
I’ve now got it se in its own workshop and set up a Vista VM on my notebook, also in the Workgroup, to manage it. That is working but I can’t help think there is a chicken and egg thing going on if you are trying to install a fresh domain on it.
Performance seems fine, but I’ve not bench tested it.
I’m having to backup files from the old SBS server across the LAN to a USB disk plugged into a workstation as the USB ports on the old server are somewhat fried. Still not bad performance though.
