Hi Praveen, <div><br></div><div>The error you are seeing is because there is no 'network' record in the nova database corresponding to 'br100' (which is the default value for the bridge). Spawning a VM requires finding the appropriate network(s) for that VM in the database, and assigning the VM an IP address from the associated network subnet. </div>
<div><br></div><div>Did you run nova-manage to create a network? If so, can you send out the command you ran? </div><div><br></div><div>For example the Running Nova wiki (<a href="http://wiki.openstack.org/RunningNova">http://wiki.openstack.org/RunningNova</a>) includes the line: </div>
