<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I mostly root caused the horizon error last night and filed a bug that ultimately was resolved as duplicate to the following:
<a href="https://bugs.launchpad.net/horizon/+bug/1040956">https://bugs.launchpad.net/horizon/+bug/1040956</a>, which I am sure the horizon people are all over now.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Until that bug is fix, horizon is pretty much useless with Quantum since you can’t spin up instances. Suspect the fix is easy enough – detect that user is dealing
with a quantum based deployment somehow and don’t try querying nova about floating ips when computing quotas.<o:p></o:p></span></p>

with, and learning about, quantum and OVS (it’s quantum and OVS I am particularly interested in, not installing openstack or spinning up VMs), so eager to see the bug get fixed asap.<o:p></o:p></span></p>

<p class="MsoNormal">One last thing. Are you running the latest devstack code? The v1 api code has been removed from quantum so you can remove the following line from rclocal NOVA_USE_QUANTUM_API=v2<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Is there a recommended procedure for upgrading nodes that were configured pre-Folsom 3 to use quantum V1/OVS that were deployed with devstack? I probably should have asked this
question before trying, but I went ahead and tried. I had a multi-node setup that I was driving with Horizon that was working very well. Now I’m just trying to get a single node setup working, and not getting far.

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">When I launched Horizon, some problems are evident. There is no launch instance button on the Instances page. Because I don’t yet know the command UI enough to spin up and configure
VMs, I figured I’d try running the devstack exercise.sh script to see what happens. It creates a few VMs, but none get an IP address (before I used to get IPs in 10.4.128.0). It reports all tests passed, as well. If I click through in the UI on the VM, I
see that for networking address it assigns all VMs is the value “Net1”. <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I’ve looked at console logs for the VMs created and see failures trying to dhcp (that’s why I naively added q-dhcp back to ENABLED_SERVICES), but as I mentioned above, adding q-dhcp
didn’t help, and I’m wondering if it was a good idea anyway since Aaron steered me away from it before.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Output of ps shows expected services running (e.g., OVS daemon, plugins, agents) and services lists displayed by Horizon (e.g., nova, quantum, etc.) all seem normal to me.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Notably missing is the OVS gw- interface that was present before I upgraded (at
<a href="http://wiki.openstack.org/RunningWQuantumV2Api" target="_blank">http://wiki.openstack.org/RunningWQuantumV2Api</a> there is this: “Note: with v2, Quantum no longer uses the L3 + NAT logic from nova-network. Quantum will not have the equivalent functionality
until F-3, so you won't be able to ping the VMs from the nova controller host.” Is that the reason?) The gw interface is the way I could ping VMs from the host.
<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"> <o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">The missing gateway, horizon UI missing the create instance button, and not getting networks for VMs spun up by devstack’s exercise script are the major symptoms. I trust that
devstack is up to sync with what is happening in Folsom, and that I am actually pulling down F3 code at this point (I’ve not tried to verify this). I’m not aware of any need to tweek the devstack exercise script, I am assuming it is designed to work as is.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I’m thinking of wiping my entire disk and starting from scratch in case blowing away /etc/nova etc. and /opt/stack were not enough to reset state, but before I do this, any pointers
to links or mail messages (I’ve scanned for relevant posts but missed finding any) that would be helpful before I do this?<o:p></o:p></p>
