Open vSwitch has worked with libvirt for a long time:
<interface type='bridge'>
<mac address='52:54:00:91:b0:3f'/>
<source bridge='ovs0'/>
<vlan>
<tag id='250'/>
</vlan>
<virtualport type='openvswitch'>
<parameters interfaceid='25f2a25d-cfed-58f8-be38-2a3d3f057233'/>
</virtualport>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03'
function='0x0'/>
</interface>
And VMs attached to Open vSwitch ports work just fine in virt-manager.
The challenge is creating such VMs. The process I use is:
1) Create new VM in virt-manager ...
- Select "Customize configuration before install"
- In "Advanced options," change the network type to "Specify shared
device name," and set the "Bridge name" to ovs0
- Click "Finish"
2) In the customization dialog, remove the NIC
3) Click "Begin Installation"
4) Complete installation without a NIC or force-off the VM (if a NIC is
needed during installation)
5) Shut down the VM
6) "virsh edit ..." to add the NIC to the VM
7) Restart the VM, complete the installation (if needed), configure the
NIC, etc.
All in all, it's a pretty ugly process.
Can you dump the NIC XML you use in a bug report against Virtualization Tools
-> virt-manager ? I'll follow up there with clarifying questions. I'll try to
get this in the the next release
Thanks,
