As Jesse mentioned, the preferred method is to not use bridge compatibility, since it requires an extra daemon and kernel module.  However, sometimes it's not possible to do that, so instructions for bridge compatibility are available in INSTALL.bridge in the distribution.  You read it online here:


Let us know if you have any questions.

> The current Xen scripts are making calls to Linux bridge commands when a VM is brought up or down.  These calls need to be converted into Open vSwitch commands.  The preferred way to do this is to actually modify the scripts to call the equivalent commands, as this generally offers better integration and a more robust solution.  The other method is to use the Open vSwitch bridge compatibility layer which will intercept the bridge commands and convert them into Open vSwitch ones.
