So you can use the whatever *default* kernel the distro has.
But in the interest of saving space, one can re-use the dom0 pvops kernel right?
If you want, you CAN use the pvops kernel there aswell.. latest versions
even have the pv-on-hvm drivers.
That's the point of the original post. The pvops 2.6.32.15 Oops's when run in hvm mode. I've tried half a dozen different config's and the result is always the same.
It's always right after this in the boot sequence (not repasting, it's in full below):

Does the pvops kernel need different boot cmdline APIC settings in hvm mode?
If pvops should work in hvm mode, then this kernel should boot. No?
