I have been working on creating an OpenStack environment according to the Basic Install <http://docs.openstack.org/folsom/basic-install/content/index.html>doc. It was working fine last night! In order to make sure I didn't mess anything up, I downed controller/network/compute nodes and cloned them (they are nested on ESXi 5.0u1).
Upon coming back up, I can't ping my guests. I'm on the network node, pinging 10.5.5.3, which is a running guest. I'm guessing the GRE tunnel isn't coming between the compute and network node, since the br-* interfaces down? (After this, I manually "ip link set up" all br-* interfaces on both compute and network-- nothing) I have no experience with either Quantum or Open vSwitch, so I don't know what this is telling me. I'm rather at a loss-- can anybody point me in the right direction here? I don't see anything in the quantum logs right now that seems to indicate an error-- openvswitch-agent.log is cycling through things like the following, though: 2013-02-27 18:19:43 DEBUG
