[ovirt-users] trunk port for vm guest

Hello, I have seen mixed results for this search on this list so I'd like to clear it up I have a VM that I need to configure with a trunk port so that all of my VLANs can be configured on it but not as separate NICs (eth0, eth1, eth2, etc) I have seen on this list about a year ago someone said to setup a network and leave it untagged and ovirt will pass all tagged and untagged packets there. Then attach this to the guest VM and configure the trunk port inside the VM (eth0:<vlan_tag>) However, I saw also about 6 months ago someone suggest something like VLAN tag 4095 so wondering if the support came in for this...or I should use untagged VM network So - how can I configure a trunk port for a guest VM? Thanks
