Title: LinuxBridge plugin fails with multiple VM NICs when gateway configs differ Status in OpenStack Neutron (virtual network service): Invalid Bug description: Specifically, the linux bridge plugin fails when spawning a VM with multiple networks, where those networks have different gateway enabled / disabled settings. Homogeneous network gateway settings for multiple networks works fine, however. In other words: -Spawning a VM with two NICs, both which have a Gateway IP configured, results in an Active instance (good) -Spawning a VM with two NICs, both which have the Gateway disabled, results in an Active instance (good) -Spawning a VM with two NICs, one which has a Gateway IP configured, and the other that has gateway disabled results in a Failed instance (bad). I have attached the stack trace for the plugin error it produced. The error seems to indicate a failure to add the tap device to the bridge, because the tap device doesn't exist. However, it does appear that the interface is being created - if only briefly before being removed. In fact I was able to run the "brctl show" command as this was happening and see each tap device get put on a bridge before disappearing 1-2 seconds afterwards. This output is also in the attachment. The one other observation I would note concerning the brctl output was that all the transient tap devices were being put on the same bridge: the one associated with VLAN 3 (eth1.3). This should only have been the case for NIC1 (first NIC). The other two should have each been on their own bridges / VLANs (eth1.6 and eth1.66).
