It's sounds like you are asking about domU (or guest) Xen-aware
kernels. In that case, mainline kernels newer than 2.6.23 should have
the support, which does include ubuntu packaged kernels (you may want
to try to stick to server, ec2, or -xen kernels as I think there were
some reports of a specific version of Ubuntu's desktop kernel lacking
xen support, perhaps accidentally, 10.04 If I recall correctly)
