I was able to get rid of this error by not specifying a default log route, i.e. log_name etc in the [DEFAULT] section.

All right, thanks for the heads up anyway! :)

Would you happen to have any details to share on this issue, bug reports or whatnot? I'm facing similar issues on a Mitaka installation that can't easily be upgraded.

Same thing happened for me, S. Boran. Tried changing dns_domain in neutron.conf, restarting neutron-dhcp-agent didn't change the --domain=openstacklocal argument to the dnsmasq process. Only when I changed dhcp_domain in dhcp_agent.ini and restarted again it works. Also running Mitaka.

Thanks for the steps on how to replace the Swift endpoint though!

CentOS 6.6 is one of the images registered in Glance, not the distro that Kilo is running on.

Having a complete and seperate Swift install is definitely a better solution and is in the works, but I'm still curious why this is one is now broken. For now, the 6.6 image is disabled (not public).

OpenStack Kilo 2015.1.1 (Mirantis)
Glance with Swift as backend (running on controllers)

When creating instances with a CentOS 6.6 image sized at 1.1 GB it fails consistently for all compute nodes but one. However when using an Ubuntu 14.04 image sized at ~250 MB it works all the time. This setup used to work, so it may have been triggered by a config change or something else.

Looking at the traceback it looks like Glance is having some issues. Tried restarting both the glance-api and glance-registry service but didn't help. Using Horizon or novaclient it initially reports as 'building', and looking at nova --debug boot [..] looks ok (checked API calls using curl).

Not sure what could be wrong, or where to look next.
