my untagged management network is 10.128.7.0/24
vlan2 should be 10.128.2.0/24
Version info is
root@vmnode2:~# ovs-vsctl -V
ovs-vsctl (Open vSwitch) 2.0.1
Compiled Feb 23 2014 14:42:32
root@vmnode2:~# virsh --version
1.2.2
I created the following network
<network>
<name>vlans</name>
<forward mode='bridge'/>
<bridge name='br0'/>
<virtualport type='openvswitch'/>
<portgroup name='vlan-01' default='yes'>
</portgroup>
<portgroup name='vlan-02'>
<vlan>
<tag id='2'/>
</vlan>
</portgroup>
<portgroup name='vlan-03'>
<vlan>
<tag id='3'/>
</vlan>
</portgroup>
<portgroup name='vlan-all'>
<vlan trunk='yes'>
<tag id='2'/>
<tag id='3'/>
</vlan>
</portgroup>
</network>
I have given my guest the following network
<interface type='network'>
<mac address='52:54:00:db:ba:70'/>
<source network='vlans'/>
<virtualport type='openvswitch'>
<parameters interfaceid='6a00da12-ff0d-42da-a12a-b00066f242c1'
profileid='vlan-02'/>
</virtualport>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
</interface>
When launch a guest VM on that vlan subnet nothing works. On the host is as
follows
