Thanks Marcus. When I added private.network.device=cloubr0 in /etc/cloud/agent/agent.properties and restarted the cloud-agent , I see the system Vms being launched successfully. We did not have to do these changes in the past. I don't think we did any of these changes when we tested RHEL 6.3 host with a build from "networkrefactor" branch sometime back.
-Thanks Sangeetha -----Original Message----- From: Marcus Sorensen [mailto:shadow...@gmail.com] Sent: Tuesday, January 29, 2013 4:45 PM To: cloudstack-dev@incubator.apache.org Subject: Re: Not able to start System Vms on KVM host This is because if there is no private.network.device config in your /etc/cloud/agent/agent.properties file, LibvirtComputingResource.java defaults to 'cloudbr1'. I would suggest setting all of your traffic labels to cloudbr0, or setting private.network.device to cloubr0. I'm assuming it was set up this way because of the recommendation that management and public be on different physical networks, but I can't really say for sure what the intention was. I think the default agent.properties file has it defined as cloudbr1 as well. I suppose this is broken since the default in the ui says 'use default gateway', which it's not doing, but I don't think it's a regression or new bug, I think it's been that way since I started using cloudstack.
