I'm trying to decide between Xen and OpenVZ. Live migration is quite the "killer app" and now that OpenVZ supports it I have some questions...
* How fast (your best guess) is it over a gigabit network with a typical guest distro? Xen's live migration downtime is microseconds; when I read that OpenVZ has "zero downtime" migration, does that mean it's microseconds, too?
* How does it work without shared hardware? Rsync+SSH?
* What if I had shared hardware, would I also need a lock manager, fencing, etc?
R U good enough?
