Unfortunately this isn't supported.

At this time, XenD does not provide a secure mechanism for connecting to it
remotely. While you can have XenD listen for TCP connections, however, there
are *zero* security checks made / authorization performed. It is not tenable
to support such an insecure connection mechanism via libvirt.

The good news is that the upstream Xen developers are aware that this is a
big problem, and in the XML-RPC protocol being developed for XenD, it appears
there will at least be some form of username/password authentication used
for remote TCP connections. Thus when the XML-RPC API for XenD is released we
will be able to more seriously look at allowing remote hypervisor connections
from libvirt.
