Does this configuration is supported ?
No. configuration of vlan tags within libvirt is only supported for
emulated devices that use a tap device connected to Open vSwitch (i.e.
(<interface type='bridge|network'> .... <virtualport
type='openvswitch'>
..."), or for SRIOV VFs that are assigned to the guest using vfio device
assignment ("<interface type='hostdev'>").
If there is a standard and reasonable method of setting up vlan tagging
for a vhostuser interface from the *host*, then we would consider
accepting patches to implement it (assuming that you want to write them :-).
Otherwise, you'll need to configure the vlan tagging to be done on the
guest (in the guest OS networking config).
I can install higher version if
required.
*Error:*
unsupported configuration: an interface of type 'vhostuser' is
requesting a vlan tag, but that is not supported for this type of connection
