I cannot say that I understand your setup, but if you have nested virtuallization (such as a Xen udom) you may experience ovirt's no-mac-spoofing rule: by default we disallow our VMs to emit traffic that has different mac address from the one assigned by oVirt. To avoid this, follow http://www.ovirt.org/Vdsm_Hooks#Installing_a_hook and report if that's the issue. _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
