[Rdo-list] RE(1) Failure to start openstack-nova-compute on Compute Node when testing delorean RC2 or CI repo on CentOS 7.1

Fri May 1 20:22:41 UTC 2015

I got the compute node working by adding the delorean-kilo.repo on compute
node,
yum updating the compute node, rebooted and extended the packstack file
from the first AIO
install with the IP of compute node and ran packstack again with
NetworkManager enabled
and did a second yum update on compute node before the 3rd packstack run,
and now it works :-)

In short, for RC2 we have to force by hand to get the nova-compute running
on compute node,
before running packstack from controller again from an existing AIO install.

Now I have 2 compute nodes (controller AIO with compute + 2nd compute) and
could spawn a
3rd cirros instance which landed on 2nd compute node.
ssh'ing into the instances over the floating ip works fine too.

Before running packstack again, I set:

EXCLUDE_SERVERS=<ip of controller>

[root at csky01 ~(keystone_osx)]# virsh list --all
