Hi,

Compilation of the xen tools natively on an ARM Ubuntu system
fails with the following message:

xc_cpuid_* are x86 specific. They should be stubbed out in both
xenctrl_stubs.c and in the ocaml equivalent (I'm not sure how to achieve
the latter). 

Your best bet is probably to disable the ocaml stuff on ARM for the time
being.

Ian.
