Use a paravirt-ops based kernel for EC2
The current EC2 kernel is based on the very large Xen patchset. A pv-ops based kernel would need a much smaller set of patches which could be maintained as a kernel flavor instead of the topic branch used for the current EC2 kernel.

status:
pv-ops: kernels have some outstanding bugs which are causing the server team some concern.
pv-on-HVM drivers postponed - there will not be an Ubuntu AMI to support the Amazon Compute Cloud in Maverick so it makes no sense to merge them at this time, instead a PPA kernel including them will be built for testing purposes.
