Feature Description Support 'passthru' mode with macvlan/macvtap to enable assigning SR-IOV VFs to a KVM guest via macvtap/virtio. In order to use this feature via virsh utility, we need to add support for a new mode 'passthru' to the domain XML format. <interface type='direct'> <mac address='54:52:20:74:60:01'/> <source dev='eth10' mode='passthru'/> <model type='virtio'/> 2.

Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
Blocking on libvirt support at the moment.
