Re: [libvirt-users] Problem with net-define using Open vSwitch bridge

Update: I have upgraded from libvirt 0.9.8 on the virtualization server to libvirt 1.0.4. Now the net-define command works with the "virtualport type='openvswitch'" directive in it. So I did a "net-edit" on the networks, added that line in, and saved them. So now I am assuming libvirt knows that the underlying bridge type is Open vSwitch. However, when I try to use virt-manager (which is 0.9.4 running on Fedora 18) to spin up a new VM and try to attach it to one of the networks I defined on the virtualization host (runs Ubuntu 12.04 Server with libvirt 1.0.4 as I had mentioned above), I am now getting the following different traceback: Unable to complete install: 'Unable to add port vnet0 to OVS bridge vl20-ovsbr0: Operation not permitted'

Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 1943, in do_install guest.start_install(False, meter=meter) File "/usr/lib/python2.7/site-packages/virtinst/Guest.py", line 1249, in start_install noboot) File "/usr/lib/python2.7/site-packages/virtinst/Guest.py", line 1317, in _create_guest dom = self.conn.createLinux(start_xml or final_xml, 0) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 2606, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: Unable to add port vnet0 to OVS bridge vl20-ovsbr0: Operation not permitted So the error went from "Operation not supported" to "Operation not permitted"... Is this some sort of a permissions error now?? If someone could please help me figure this out, that would be great, as I'm up against a bit of a deadline with this to get it working...

The net-define worked fine, I can see the network in "net-list" (I set it to started and to autostart) but when I try to attach a new VM's NIC to this network (via virt-manager), I'm getting the following traceback: Unable to complete install: 'Unable to add bridge vl10-ovsbr0 port vnet0: Operation not supported' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/create.py", line 1943, in do_install guest.start_install(False, meter=meter) File "/usr/lib/python2.7/site-packages/virtinst/Guest.py", line 1249, in start_install noboot) File "/usr/lib/python2.7/site-packages/virtinst/Guest.py", line 1317, in _create_guest dom = self.conn.createLinux(start_xml or final_xml, 0) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 2606, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: Unable to add bridge vl10-ovsbr0 port vnet0: Operation not supported I'm going to assume the problem is that the bridge is not a linux bridge, but an Open vSwitch bridge. But I did have a line in the XML file that I used for net-define as follows: <virtualport type='openvswitch'/> But when I ran net-define, it failed to create the network with the error: XML error: unexpected virtualport type -1 Removing that line and re-running the net-define worked, as I have stated above. How do I tell libvirt that this bridge is an Open vSwitch bridge and not a regular Linux bridge?
