recommendations on virtualization software

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.
