I am trying to create a VM with its port attached to the OVS bridge. I have
created an OVS bridge br0 and then followed instructions mentioned on this
page to edit the XML file of VM:
http://docs.openvswitch.org/en/latest/howto/libvirt/
I have updated my Domain XML file for the VM to something like this:
<interface type='bridge'>
<mac address='52:54:00:b1:72:f7'/>
<source bridge='br0'/>
<virtualport type='openvswitch'>
<parameters interfaceid='193246cd-d7b8-4bbb-8ad7-4b0b4c933004'/>
</virtualport>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07'
function='0x0'/>
</interface>
But, as soon as I start VM using the Virtual Machine Manager, I get this
error: *Error starting domain: internal error: Unable to add port vnet0 to
OVS bridge br0*
This explanation is given for the error:
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 90, in
cb_wrapper
callback(asyncjob, *args, **kwargs)
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 126, in tmpcb
callback(*args, **kwargs)
File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 83, in

ret = fn(self, *args, **kwargs)
File "/usr/share/virt-manager/virtManager/domain.py", line 1402, in
startup
self._backend.create()
File "/usr/lib/python2.7/dist-packages/libvirt.py", line 1035, in create
if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error: Unable to add port vnet0 to OVS bridge br0
I am very new to this tool and am not able to figure out what could be done
to resolve this error. Any help in this regard would be great.

Harsh
