We try to update vlan tag by running virsh update-device command,
libvirtd will report ovs-vsctl arguments error. Vlan tag update
funtion does't consider the xml with no vlan configured circumstances.
The steps to reproduce the problem:
1 define and start domain with its vlan configured as:
<interface type='bridge'>
<mac address='52:54:00:9e:bb:ac'/>
<source bridge='ovs-br0'/>
<vlan>
<tag id='10'/>
</vlan>
<virtualport type='openvswitch'>
</virtualport>
<target dev='vnet4.0'/>
<model type='virtio'/>
<driver name='vhost'/>
</interface>
2 define and run virsh update-device command with no vlan configured as:
<interface type='bridge'>
<mac address='52:54:00:9e:bb:ac'/>
<source bridge='ovs-br0'/>
<virtualport type='openvswitch'>
</virtualport>
<target dev='vnet4.0'/>
<model type='virtio'/>
<driver name='vhost'/>
</interface>
#virsh update-device dom-id novlan.xml
3 virsh command returned error, and we got an error in libvirtd.log:
error : virCommandWait:2584 : internal error: exit status 1: ovs-vsctl: 'set' command requires at least 3 arguments
. Child process (ovs-vsctl --timeout=5 -- --if-exists clear Port vnet4.0 tag -- --if-exists clear Port vnet4.0 trunk
-- --if-exists clear Port vnet4.0 vlan_mode -- --if-exists set Port vnet4.0) unexpected
error : virNetDevOpenvswitchUpdateVlan:540 : internal error: Unable to set vlan configuration on port vnet4.0

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
Further information about the libvirt project can be found on the website:
