Are you running glance over ssl? We had an fairly random but consistent issue with vm's being stuck building. Usually building means (at least what I found) the compute node did not have the backing image for the vm and needs to download it from glance , convert it from what ever backing file it was to a raw image, then start a qcow2 instances backed by the raw file. Assuming you are the default configured raw backend qcow2. You can check this by logging into the compute node and looking under: /var/nova/instances/_base/ for a <sha1 of imageuuid>.part file that is not growing, fir you do find one - then most likely you are seeing the same issue.
I posted about this on the mailing list a while back: http://www.gossamer-threads.com/lists/openstack/operators/39669 And also made a bug posting: https://bugs.launchpad.net/glance/+bug/1340993 The bug posting included some scripts to duplicate/verify the issue. In the end we moved ssl termination to haproxy on the same box as glance and the issues went away. ____________________________________________ Kris Lindgren Senior Linux Systems Engineer GoDaddy, LLC.

After I terminate that instance and try again, it mostly goes through fine. This is happening across multiple projects/tenants and seems to affect all users. Does anyone know this issue and/or has any suggestions or links or docs to read up on to troubleshoot this ? Thanks! Alex
