That was the OVS note all about, only with an OVS bridge it is possible to
define/select the vlans which are exposed
to the VM vnic. But this is not available at the moment.
As Rogério mentioned, define the VLAN/s on the VM vnic.

I think you define vlans on vm virtual nic OS like you do as usual. Monday
i will try and share results. Bye.

Great !

What about a range of VLANs, is it also supported ?

Re: [ovirt-users] Passing VLAN trunk to VM

[Edward Haas]

Passing a trunk to the vnic is supported long ago.
Just create a network over a nic/bond that is connected to a trunk port and
do not define any VLAN (we call it non vlan network).
In oVirt, a non-vlan network will ignore the VLAN tag and will forward the
packets as is onward.
It is up to the VM vnic to define vlans or use a promisc mode to see
everything.

OVS can add a layer of security over the existing, by defining explicitly
which vlans are allowed for a specific vnic, but it is not
currently available.

I was wondering if open vswitch will get round this problem. Has anyone

Re: [ovirt-users] Passing VLAN trunk to VM

[Nathanaël Blanchet]

You can try to passthrough a dedicated nic for the pfsense vm.

Note if you need several (up to 64) vms with a trunk and if your (often 
10Gb )nic supports virtual function, you can use sr-iov so as to share 
your PV into 64 VFs.
