Thank you for the explanation.

What Martin said is correct, let me just add that originally this
limitation was put in place because in older kernels the bridge for the
untagged network could see tagged traffic over the same physical
interface, which was a security loophole (as a VM using the untagged
bridge could sniff all the traffic on the physical interface).
This isn't the case anymore, so in 3.6 we want to remove this limitation.

Hi,
it is possible to achieve the state you describe. You just can’t have ovirtmgmt
as VM network in such case.
You need to set ovirtmgmt as nonVM [1] (aka bridgeless network), then you can
put it on one interface with VLANs.
Be aware that you can put on one interface only one bridges network + multiple
VLANs.

Hi all,
On a standalone libvirt/KVM, I've been used to mix tagged and untagged vlans on
the same interface, the untagged vlan dedicated to the physical interface em1
and the other tagged ones to VLAN em1.X.
I've just installed a new datacenter with an untagged ovirtmgmt and then
realized that I've been prevented from attaching additional vlan to the same
inetrface.
Is there a reason for that, knowing that nothing should technically be wrong?
