As a matter of fact, as far as I know virt-install hasn't been enhanced to support direct description of an openvswitch bridge on its commandline. The best way to solve this problem is to create a libvirt network to encapsulate the openvswitch bridge, then tell virt-install to use that network. 1) Put the following xml into a file (e.g. /tmp/ovsnet.xml): <network> <name>ovs-br0</name> <forward mode='bridge'/> <bridge name='br0'/> <virtualport type='openvswitch'/> </network> 2) define and start the network: # virsh net-define /tmp/ovsnet.xml # virsh net-start ovs-br0 # virsh net-autostart ovs-br0 3) run virt-install telling it to use the network "ovs-net": # virt-install --connect qemu:///system --name DSL2 --ram 1024 --vcpus 1 \ --disk path=/tmp/dsl2,size=1,bus=virtio,cache=none \ --network=ovs-br0 \ <======= THIS LINE IS CHANGED. --vnc --os-type=linux --cdrom /dev/sr0 <o:p></o:p> </div> </body> </html>
