devstack

Installing Devstack on Xenserver triggers a urllib3.connectionpool warning, followed by a 409 Conflict: Cannot upload to an unqueued image.

Asked by Theora Rice

Hello. The project I am trying to execute involves installing devstack onto Xenserver 6.5. This seemed pretty straight forward,
at least as described by https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md. However I have had a number of errors. Most I have been able to fix through various forum posts, but this particular problem has eluded answers.

My configuration is XenServer 6.5 installed on a server, with the latest version of devstack downloaded on the host. As guided in the README, I trigger ./install_os_domU.sh, which creates the DevStackOSDomU vm (in this circumstance, IP: 192.168.2.230) that will run devstack. However, while stack.sh is running (as part of run.sh) on DevStackOSDomU, the following error occurs and shuts down the install:

As you can see, the error repeats three times, then errors out. Devstack does not end up installing, and cannot be run. I can't seem to see why the
HttpConnectionPool would be full from the logs of the process, and this doesn't seem to be a common error in installing devstack on Xenserver.
I'm wondering if the warning is connected to the error. Has anyone run into this problem before, or understand a potential way to solve it?

Thank you for your time.

I believe I just fixed the problem. Apparently, the stack.sh script iterated multiple times through the last element of the IMAGE_URLS variable that I set in localrc. When I got rid of the comma in that list, and changed stack.sh to just read white space as the element separator of a list (as is the default), the script completed without further error.

To illustrate:

(In localrc) IMAGE_URLS="\ https : //github.com/downloads/citrix-openstack/warehouse/cirros-0.3.0-x86_64-disk.vhd.tgz,\ http : //download.cirros-cloud.net/0.3.2/cirros-0.3.2-x86_64-uec.tar.gz" (From the devstack/tools/xen/readme)

Became IMAGE_URLS="https : //github.com/downloads/citrix-openstack/warehouse/cirros-0.3.0-x86_64-disk.vhd.tgz http : //download.cirros-cloud.net/0.3.2/cirros-0.3.2-x86_64-uec.tar.gz"

(And in stack.sh) for image_url in ${IMAGE_URLS//,/ }; do

Became for image_url in ${IMAGE_URLS}; do

At the moment there is no fix in devstack code (master).
I think that this issue should be open until the fix.

I'm not sure I understand the issue here, or the proposed fix. The "cirros-0.3.2-x86_64-uec.tar.gz" download contains three files that need to be uploaded to Glance.

I wonder if the issue is that somehow the IMAGE_URLS got extended to include the last element multiple times, going through a different path of the devstack code?

We're running with the original code without issue.
