Just tried: * RDO Havana (not the nightlies. I used the stable repos) * RHEL 6.4.z + 114.openstack.gre.2 kernel (in the RDO Havana repo) * allinone install on a VM running on top of a Fedora host * Neutron enabled! And was able to successfully boot a cirros instance, and run the usual tests (outbound connectivity, FIP access via ssh/ping) I ran this with the base image where my host network interfaces were managed by NetworkManager, and I didn't notice any ill effects. The _one_ caveat is that there were selinux denials, probably having to do with the quantum/neutron renaming. Terry Wilson found this earlier when he ran some tests, so I was able to run setenforce Permissive before running the packstack install to avoid those issues (Terry filed bugs 996773 and 996776 for these issues) Next up, to try out Bob's GRE instructions to see if I can get a multi-node setup running with tunneling. Cheers, Perry
