Jeff from the Microsoft Windows Server Virtualization team posted yesterday on their team blog the first in a promised 4 part series on Hyper-V HA and Quick Migration and it's differences with VMware's VMotion or live migration. This first post doesn't really get into the differences, but does a good job of explaining why you need an HA for a virtualizaiton solution.

I am really looking forward the other posts to get the full rundown on quick migration. Jeff makes a reference that this series of posts is in response to "buzz" on the internet. I can only guess that part of that buzz is due to things like a recent video posted by David Marshall on vmblog.com showing Hyper-V Quick Migration in action, and discussions in a few places including the RTFM Education blog, blog.scottlowe.org, and the From the VMware Field Blog.

So it will be good to get Microsoft's side of the story.
