I'm currently using Xen since all the guests I have are Linux. How hard
is it to migrate from Xen to KVM if I wanted to go that route?
To expand a bit on what I'm doing, I have four guests that run
independent Debian Etch instances, and each of which is backed by DRBD
running on two servers, so if we have to take one down for maintenance
or hardware issue, it can be quickly brought up on the other server.
This has worked out pretty well since we wanted to migrate to new
hardware. The actual downtime for each of the guests while I migrated
them was under a minute. I could then rebuild the unused box, bring it
back up, and then move the guests back.
