which 2.6.32? vanilla? pv_ops from Jeremy's tree?

I usually simply copy Redhat's /boot/config-* to .config, and run
"make menuconfig", adjusting options as needed. However when moving to
pv_ops from -xen kernel, many xen-related options changed, so you'd
ended up having to look at them manualy anyway.

If you're feeling lazy, just install Oracle's enterprise kernel from
http://public-yum.oracle.com/
Their 2.6.32 kernel works for pv domU as well. However, since block
device name becames xvd*, you need to edit domU's fstab manually first
to use LABEL or UUID, otherwise the kernel rpm's postinstall script
will fail to run.
