Hi all, How do you add a VLAN tag to a libvirt SR-IOV VF network usingthe "virsh net-update" command? I couldn't find the section to passto the "virsh net-update" command to add the VLAN tag. I have the following libvirt network defined for a SR-IOV VF: <network> <name>GE0-0-SRIOV-1</name> <uuid>7bc67166-c78e-4bcf-89ee-377dd9086631</uuid> <forward mode='hostdev' managed='yes'> <driver name='vfio'/> <address type='pci' domain='0x0000' bus='0x02' slot='0x10' function='0x0'/> </forward></network>
I am trying to add VLAN 100 to this network. If I use the following command toadd a VLAN tag to this network: virsh net-update GE0-0-SRIOV-1 modify bridge --xml "<vlan trunk='no'><tag id='100'/></vlan>" It fails as the section "bridge" doesn't support adding a VLAN tag. I have triedother section values like domain and all of them fail. I am able to add the VLAN to the portgroup section, but then the VLAN configurationis not propagated to the underlying physical PF interface. If I manually add the VLAN configuration using the "virsh net-edit" command andthen connect a VM to this network, then the VLAN information is correctly propagatedto the underlying physical NIC device. I need a way to automate this configuration. Any pointers? Thanks,Yegappan
