I can believe that. My only experience is with Amazon, which doesn't
give you any control over the host xen. It just runs grub with a
grub.cfg you provide if you want to run your own kernel (unless that
has changed).

I believe that EC2 ONLY provides PV guests. I don't believe it will
do full virtualization for linux guests. They do provide windows
guests, and I'm not sure of the details of how that is done. If you
want to run a linux guest you either use one of their kernels, or you
can run your own as long as it supports Xen PV.
