Yes , works both ways ( delorean.repo installed on Compute node as well)
CONFIG_CONTROLLER_HOST=192.169.142.127
CONFIG_COMPUTE_HOSTS=192.169.142.137
CONFIG_NETWORK_HOSTS=192.169.142.127
with separate network for VTEP's interfaces
Bridge br-tun
fail_mode: secure
Port patch-int
Interface patch-int
type: patch
options: {peer=patch-tun}
Port "vxlan-c0a87a89"
Interface "vxlan-c0a87a89"
type: vxlan
options: {df_default="true", in_key=flow, local_ip="192.168.122.127", out_key=flow, remote_ip="192.168.122.137"}
RC2 looks fine (CentOS 7.1 yum updated)

Yes, it looks possible to perform multi node deployment with RDO Kilo RC2 via single packstack run.
I've tried:-
CONFIG_CONTROLLER_HOST=192.169.142.127
CONFIG_COMPUTE_HOSTS=192.169.142.127,192.169.142.137
CONFIG_NETWORK_HOSTS=192.169.142.127
was able use different IPs for VTEPs ( CONFIG_TUNNEL_IF=eth1 works as expected ).
Bridge br-tun
fail_mode: secure
Port "vxlan-0a000089"
Interface "vxlan-0a000089"
type: vxlan
options: {df_default="true", in_key=flow, local_ip="10.0.0.127", out_key=flow, remote_ip="10.0.0.137"}
and succeeded .
Per your report looks like 192.169.142.127 may be removed from CONFIG_COMPUTE_HOSTS.
AIO host plus separate Compute node setups scared me too much ;)
The point seems to be presence of delorean.repo on Compute nodes. Am I correct ?
My testing resources are limited 16 GB RAM and 4CORE CPU , I cannot start third VM for testing

I just used VMs with eth0 for public && management network and eth1 for VXLAN endpoints

Thank you for keeping me posted.

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 Kilobecomes 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!

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.

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 AIOinstall with the IP of compute node and ran packstack again with NetworkManager enabledand 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 a3rd 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>
