[ovs-discuss] Unable to install OVS on XenVM

[Justin Pettit]

It's claiming you have more than one instance of ovs-vswitchd running.  Make sure you're only one instance and that your paths are all correct.  ovs-ofctl will look in the run path configured during build time for a unix domain socket representing the bridge.  Your ovs-ofctl man page will show you where it will look for that socket.  For example, from my local repo:

	bridge This is short for unix://var/run/openvswitch/bridge.mgmt, as long as bridge does not contain a colon.
