Hey Frank It's a replacement for linux bridge at the moment.
It uses ova-vsctl to create and check bridge interfaces and it used the virtualinterface tags in libvirt to create the virtual interfaces with ovs. The main reason for doing this type of integration was that openvswitch is required on a KVM hypervisor for it to be used with Nicira and the CloudStack nicira plugin. So i needed to make sure that bridge configuration could work with ovs. Cheers, Hugo On Feb 7, 2013, at 11:20 PM, Frank Zhang <frank.zh...@citrix.com> wrote: > Curious question, what level of support do we have in this feature? > Is it a simple replacement for Linux bridge?
