The xm_internal.c driver (that processes /etc/xen config files) is only ever
intended to be used on XenD <= 3.0.3 There are impls of all the methods in
xend_internal.c that take priority on newer XenD, since the xend driver is
before it in the stack. The only flaw is that upon failure of one of the
xend method libvirt will carry on & invoke the xm_internal driver method.
The attached patch addresses this by completely disabling the xm_internal
driver on XenD >= 3.0.4
Dan.
