To do kexec on PV guests is there a dependency on support from the dom0?

e.g. if we recreated your patches and merged them into 3.12 and booted
on a XenServer from a few years ago would it work?

What I want to do is use kexec on existing public cloud providers,
that use Xen, like AWS or Rackspace.

Thanks,
