If i understand you right. I have to build kernel per your instructions.
scp this kernel (say "vmlinux") to Ubuntu Karmic HVM DomU.
Login into Ubuntu Karmic HVM DomU and attempt  :-
# ./vmlinux

Boris.
P.S.
Patched Xen 4.0-rc6 & 2.6.32.9 Dom0 already loaded.
Branch xen/pvhvm-stefano checked out and kernel 2.6.32 has been tuned as advised.
Now is building. I have not notice any option to activate backends in yours kernel.

An HVM domain is similar to a normal qemu emulated machine, so I meant a
kernel that is able to boot on that machine (x86 support, e1000 driver, etc.).

In addition to that if you want to enable PV on HVM you need support for
the PV frontends: enable CONFIG_XEN, CONFIG_XEN_BLKDEV_FRONTEND,
CONFIG_XEN_NETDEV_FRONTEND, CONFIG_XEN_XENBUS_FRONTEND,
CONFIG_XEN_PLATFORM_PCI; avoid the BACKENDs.
