Murali, Benoit, First, thanks for the tip, I knew about /var/log/ovstunnel.log from CS 4.1.1 but had no idea it moved under "cloud" folder :) I am on a fresh installed setup.
So, looking at this log, I am seeing something that looks like this: ---- 2014-03-31 22:01:26 DEBUG [root] Entering create_tunnel 2014-03-31 22:01:26 DEBUG [root] Executing:['/usr/bin/ovs-vsctl', '--timeout=30', 'wait-until', 'bridge', 'xapi4', '--', 'get', 'bridge', 'xapi4', 'name'] 2014-03-31 22:01:56 DEBUG [root] The command exited with the error code: -14 (stderr output:) ---- This is not happening all the time. A second attempt to create an instance did create the tunnel successfully. I was actually seeing something similar in our previous setup which was CS 4.1.1 + XenServer 6.1.0 Florin -----Original Message----- From: benoit lair [mailto:kurushi4...@gmail.com] Sent: Tuesday, April 01, 2014 9:22 AM To: dev@cloudstack.apache.org Subject: Re: OVS plugin communication failure (CS 4.3.0) Hello Florin, Are you on a fresh install or on an upgraded version (from 4.1 ?)
