Jeff, AFAIK paravirtualisation is no longer considered the way to go (unless you lack virt support in CPU). I always prefer Other/Misc profiles in Xenserver, gives me a more "proper" OS, even when using linux. BTW most linux distros will enable paravirt drivers to access disk and network.
Even Amazon recommends HVM: "for the best performance, we recommend that you use current generation instance types and HVM AMIs when you launch new instances.". http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/virtualization_types.html HTH Lucian -- Sent from the Delta quadrant using Borg technology!
