That's not PV domU. It's HVM Linux domU with PV drivers. I haven't
tried one of those, sorry.

Is there a special reason why you don't use PV domU instead? Centos
4.x has kernel-xenU for that purpose. It should provide much better
performance, plus a working live migration.

Really? RHEL5 has kmod-xenpv-0.1-9.el5.x86_64.rpm. You can either
rebuild that from SRPM, or wait several weeks for CentOS 5.3. See
