Got it! The issue is that the guest VMs weren't getting the DHCPOFFER response from my internal network's DHCP server because of the way the OpenStack's Access & Security policies were configured. The step missing in the Quickstart Guide was to add an Ingress rule for Custom UDP using port 68!

Hope this helps other people having similar issues

It took a while, but I was able to access the cirros image via the console! (It seems the console was blocking on the DHCP discovery of the IP addresses of the interfaces.

I was able to log in, but all I was able to confirm is that the instance wasn't getting its IP address from the DHCP server. I'm assuming that the DHCP server in this case is the one that comes with OpenStack (neutron? nova?). Is there any way to see the logs from either the layer 2 of the virtual bridge or from the OpenStack DHCP server?

I've done a pretty thorough search of the Q&A's here using as many keywords I can think of and can't seem to find an answer to my issue (though I'm finding a lot of people with similar issues but no resolution)

I've followed the Quickstart Guide in RDO for creating an allinone Openstack installation and configured it to work with an existing network. I have an existing network (192.168.1.0/24) on my LAN to which this new CentOS 7 running OpenStack Kilo is connected. I followed the guide and made modifications to the startup scripts of my host OS to configure the br-ex bridge and enp7s0 interface as an interface on that bridge. I've also created a private network (192.168.100.0/24 following the defaults of the guide). I've imported 3 different images (CentOS 7, Fedora 22 and CirrOS qcow2 images from the official repositories and started instances assigning private and public interfaces to all. In all cases, I cannot access the VM instances from my host (either via ICMP ping or SSH). I can access the console but cannot login as the images don't have passwords. The trick to override the passwords either via the Post-Creation script (password: mypassword) or the API ('nova root-password <instance-id>') don't seem to work (the last one resulting in a:

ERROR (HTTPNotImplemented): Unable to set password on instance (HTTP 501) (Request-ID: req-65fa3132-4003-45dd-ab15-4070404ed2f2)
). From the Fedora console-log, it looks like the network interfaces aren't coming up:
