Comment 0 for bug 1312016

Hello: My OpenStack's version is 2013.1.5(G) , plugin is linuxbridge ,os is ubuntu12.04.3 ,

When i launch three instances , two instances is successful, and one of the three is failed to spawn .

I check the log of nova-compute , I found eth following errors :

(it's worth noting that:
"libvirtError: Unable to add bridge brq233a5889-2e port tap3f81c08a-39: Device or resource busy")

Somebody in the same problem?
