Public bug reported: Something is broken here:
https://github.com/openstack/nova/blob/af78b13c24d4abf393d17ac57e9135204ef12b73/nova/virt/block_device.py#L836 Because I'm seeing this getting logged: https://github.com/openstack/nova/blob/af78b13c24d4abf393d17ac57e9135204ef12b73/nova/virt/block_device.py#L855 When I know I'm booting from an existing volume. This is also all over the CI logs: http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22Booting%20with%20blank%20volume%20at%5C%22%20AND%20tags%3A%5C%22screen-n-cpu.txt%5C%22&from=7d My guess is something with dict get() access changed on the DriverVolumeBlockDevice code with this change: https://github.com/openstack/nova/commit/b958bf1126aea8b88ccebb43a330fc1a44717145 #diff-40dadeaa854473fb72fa4bf3491a434f If I change the code to check: if bdm.volume_id: ... Then I get the expected log message but that is probably dangerous if we have a non-volume BDM. ** Affects: nova Importance: Medium Status: Confirmed ** Tags: compute serviceability volumes -- You received this bug notification because you are a member of Yahoo!
