I tried to follow previous changes. This worked for me using Xen-4.3
and the xm stack (I know rather deprecated but as long as one can get
it working, still).

Subject: [PATCH] xen: Add interface versions for Xen 4.3
Xen 4.3 changes sysctl version to 0xA and domctl version to 0x9. Update
the hypervisor driver to work with those.
