Because Xen colo-frame based on Xen Remus.
Remus do some job like the migration job in qemu/kvm, and in Xen HVM we 
can not do migration in qemu,
So colo-frame code must running in Xen side.
In addition, Xen HVM use qemu to simulation device that Colo-proxy and 
Replication can use same one codes in qemu.
