I just finished live migration of hyper-v guest on Windows 2012, I like much, so I like to migrate more of other virtual machines and physical machines to it. Before I do that, I may have to set up a backup Hyper-v server so that in case of something happens, i like to move guests to the backup server.
How do you guys plan to setup a backup Hyper-v host machine? What is your strategy?
I have a unused Windows 2008 R2 license. If I install it on the new server, is it possible to upgrade to the same version of Hyper-v running on Windows 2012 and use as backup Hyper-v host machine so that I can do live migration between the two servers? How do I upgrade Hyper-v on Windows 2008 to resolve this possible compatibility issue. Do I add Hyper-v role in Windows 2008 first, then upgrade or install stand-alone Hyper-v Server 2012 on it?
Also, how about using Windows 8 with Hyper-V? Can I do live migration between Windows 8 and Windows 2012 for guests installed?
