I do not have any hands-on experience with libvirt and KVM, but from talking to other people who have used OVS with libvirt, I was under the impression that libvirt provides a mechanism by which you can bring up VM interface devices using an arbitrary script. The libvirt docs (http://libvirt.org/formatdomain.html#elementsNICSEthernet ) mention: Generic ethernet connection Provides a means for the administrator to execute an arbitrary script to connect the guest's network to the LAN. The guest will have a tun device created with a name of vnetN, which can also be overridden with the <target> element. After creating the tun device a shell script will be run which is expected to do whatever host network integration is required. By default this script is called /etc/qemu-ifup but can be overridden. ... <devices> <interface type='ethernet'/> ... <interface type='ethernet'> <target dev='vnet7'/> <script path='/etc/qemu-ifup-mynet'/> </interface> </devices> ... I am guessing such a script might let you override libvirt's mechanism for adding a VM interface device to the bridge and instead let you directly configure it using OVS (e.g., ovs-vsctl set port netwin0 tag=6 ). As I recall, you're not the first person to have this problem so however we end up resolving it, we should document this better on the OVS site. dan > The old conf file mode made running VM's with libvirtd/qemu very > easy/elegant. > Do I have any options to get this working with 1.0.0? > > Thanks in advance. > > Mark > > > > > > > > > > Please consider the environment before you print this email > For email conditions, please see our website > http://www.superchoice.com.au/email_conditions.htm > > _______________________________________________ > discuss mailing list > discuss@openvswitch.org > http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org >
