No noticeable interruption... It doesn't suspend (like the old SAVEVM/RESTVM), it migrates the live, in storage memory to the new box while the server continues to run on the old box. It keeps track of what pages have been changed as the server runs on the old box and gradually trims that set of pages down so there's a minimal number of pages that have to be transferred "all at once" at the end as control is passed to the new server.
I've tried vanilla web serving and ftp during the moves, and I've never noticed a pause. And like I said, their demo is to move a server that's streaming video, also with no noticeable pause...

Won't there be some interruption time between the suspend-to-disk on the first set of servers, and the resume-from-disk on the second set? That is, the servers don't know they were down, but connected guests will see a pause there, won't they?
