<br>
I'm setting up openstack on some machines using<br>
<a href="https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst" target="_blank">https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst</a>.<br>
<br>
I'm using 3 nodes: a controller, network node and compute node. All the<br>
network interfaces are VLAN tagged use the same underlying physical 10G,<br>
e.g.,<br>
<br>
controller: p1p1.4 (public net: 192.168.251.*/24), p1p1.5 (management<br>
net: 10.10.10.*/24)<br>
network: p1p1.4 (public net: 192.168.251.*/24), p1p1.5 (management<br>
net: 10.10.10.*/24), p1p1.6 (vm net: 10.20.20.*/24)<br>
<br>
# I haven't gotten to the compute node yet but it should be<br>
compute: p1p1.5 (management net: 10.10.10.*/24), p1p1.6 (vm net:<br>
10.20.20.*/24)<br>
<br>
When I bring up my openvswitch bridges on the network node, I can not<br>
longer get out to the public net (see *MORE* below).<br>
<br>
I'm running ubuntu 12.10 and have run apt-get dist-upgrade. The 10G<br>
nics are intel 82599EB. ubuntu seems a bit flakey; initially I'd<br>
created /etc/udev/rules/70-persistent-net.rules to map p1p1 to eth2,<br>
however, the config was ignored and eth2 wound up being a 1G NIC.<br>
<br>
Is it not allowed to use VLAN interfaces for my networks?<br>
<br>
If I remove, say, the br-ex bridge I can get out again:<br>
