Hi Ruby,

At present, there is no way to do this with xm. In the hypervisor,
each struct domain has an is_privileged attribute (which is at present
only set when dom0 is created at boot). You could add a domctl to
control the setting of this bit, and then write a small C program that
uses do_domctl from libxc to set the privilege on a domain.

However, simply running two privileged domains with parallel sets of
Xen tools is unlikely to work, for example because you will end up
with two instances of XenStore.

Regards,

Derek Murray.
