Can you create the DomU on the E5140 and then migrate it to the others? That might start it with the minimum feature set required (assuming the E5620 features are a superset of the E5140) James _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
