I've created a QCOW2 image from tiny core linux. The image boots and runs fine using KVM. I've uploaded the image to openstack and tried creating an instance. I used the "tiny" model. The launch initializes, the status changes from Building->Spawning-Error. I click into the instance, select "log" and I get:

 Unable to get log for instance "17a79fc0-1fc2-462d-987e-ad82bd741e30".

I select "Console" and I get:

console is currently unavailable. Please try again later. Reload

In the screen logs (screen_n_cpu) I'm seeingthe following. It seems to be complaining about bridge "br-int". I've no idea what this means and I'm not seeing br-int anywhere.

I had to set SCREEN_LOGDIR in my localrc for the logfiles to materialize.

It means that command :-

    [root@dfw02 ~(keystone_admin)]$ ovs-vsctl add-br br-int

was skipped during setup. Without br-int you appear to be unable to confure neutron-l3-agent

View Install the Open vSwitch (OVS) plug-in
Install and configure the network node

Thanks. Issued ovs-vsctl add-br br-int manually and I'm able to launch the instance now.
