Hi,
I'm using Centos 5.2 with OFED 1.3 (Infiniband Drivers), Xen 3.3.0 from
Gitco RPM and DRBD 8.2.6 installed. I have always installed the VMs as
full HVM and modified them later for PV. I used an rpm called
kmod-xenpv-0.1-10.el4.centos.x86_64 to change the Centos 4.7 HVM to
para, it gave a good increase in performance but unfortunately a
suitable KMod does not seem to be available for Centos 5.2 yet.
Below are the Xen logs during transfer of a PV VM. Does anything look
out of place?
Thanks,
Rob

Now that's weird. What OS/Xen combo are you using? Have you test it
with RHEL/CentOS 5.2 PV domUs?
