[ovirt-users] Passing VLAN trunk to VM

Is it possible to pass multiple VLANs to a VM (pfSense) using a single virtual NIC? All my existing oVirt networks are setup as a single tagged VLAN. I know this didn't used to be supported but wondered if this has changed. My other option is to pass each VLAN as a separate NIC to the VM however if I needed to add a new VLAN I would have to add a new interface and reboot the VM as hot-add of NICs is not supported by pfSense.
