Hi all, from here [1]:
"Network connections that support guest-transparent VLAN tagging include 1) type='bridge' interfaces connected to an Open vSwitch bridge Since 0.10.0 , 2) SRIOV Virtual Functions (VF) used via type='hostdev' (direct device assignment) Since 0.10.0 , and 3) SRIOV VFs used via type='direct' with mode='passthrough' (macvtap "passthru" mode) Since 1.3.5 . All other connection types, including standard linux bridges and libvirt's own virtual networks, do not support it."
I read it correctly that when used on a classical linux bridge these vlan tags does nothing? If so, it is due to something related to the underlying bridge device (ie: incomplete support for vlan filtering) or it is because libvirt lacks the necessary "plumbing" to use advanced bridge features?
AFAIK it was simply never implemented. There's also an upstream feature request for this: https://gitlab.com/libvirt/libvirt/-/issues/157
Thanks.
