Boris, thanks for your kind feedback.

I did a 3 node Kilo RC2 virt setup on top of my Kilo RC2 which was installed on bare metal.
The installation was successful by the first run.

The network looks like this:
https://cloudssky.com/.galleries/images/kilo-virt-setup.png

For this setup I added the latest CentOS cloud image to glance, ran an instance (controller), enabled root login,
added ifcfg-eth1 to the instance, created a snapshot from the controller, added the repos to this instance, yum updated,
rebooted and spawn the network and compute1 vm nodes from that snapshot.
(To be able to ssh into the VMs over 20.0.1.0 network, I created the gate VM with a floating ip assigned and installed OpenVPN
on it.)

What I noticed here, if I associate a floating ip to a VM with 2 interfaces, then I'll lose the connectivity to the instance and Kilo
becomes crazy (the AIO controller on bare metal lose somehow its br-ex interface, but I didn't try to reproduce it again).

The packstack file was created in interactive mode with:

packstack --answer-file= --> press enter

I accepted most default values and selected trove and heat to be installed.

The answers are on pastebin:

http://pastebin.com/SYp8Qf7d

The generated packstack file is here:

http://pastebin.com/XqJuvQxf

The br-ex interfaces and changes to eth0 are created on network and compute nodes correctly (output below).

And one nice thing for me coming from Havana was to see how easy has got to create an image in Horizon
by uploading an image file (in my case rancheros.iso and centos.qcow2 worked like a charm).

Now its time to discover Ironic, Trove and Manila and if someone has some tips or guidelines on how to test these
new exciting things or has any news about Murano or Magnum on RDO, then I'll be more lucky and excited
as I'm now about Kilo :-)

Thanks!
Arash

with only one issue:-

 during AIO run CONFIG_NEUTRON_OVS_TUNNEL_IF=
 during Compute Node setup CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1

 and finally it results mess in ml2_vxlan_endpoints table. I had manually update
 ml2_vxlan_endpoints and restart   neutron-openvswitch-agent.service on both nodes
 afterwards VMs on compute node obtained access to meta-data server.

 I also believe that synchronized delete records from tables "compute_nodes && services" 
 ( along with disabling nova-compute on Controller)  could  turn AIO host into real Controller.

Subject: Re: [Rdo-list] RE(1) Failure to start openstack-nova-compute on Compute Node when testing delorean RC2 or CI repo on CentOS 7.1
From: ak@cloudssky.com
To: bderzhavets@hotmail.com
CC: apevec@gmail.com; rdo-list@redhat.com

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>
