Dennis, the dom0 and domU's are both virtual machines on top of the Xen hypervisor. In short, the only difference between the two is that dom0 has additional permissions to control the hypervisor (and thus it has xend and the other management tools). The performance should therefore be equal in dom0 and domU. All the best, Henrik -- Henrik Holmboe, Stockholm, Sweden <http://henrik.holmboe.se/contact/>
