Public bug reported: Due to nova.virt.driver:LibvirtDriver.get_guest_config prepends instance root_device_name with 'dev' prefix, root_device_name may not coincide with device_name in block device mapping structure. In this case describe instances operation reports wrong instance type: instance-store instead of ebs.
Environment: DevStack Steps to reproduce: 1 Create volume backed instance passgin vda as root device name $ cinder create --image-id xxx 1 $ nova boot --flavor m1.nano --image xxx --block-device-mapping vda=yyy:::1 inst Note. I used cirros ami image. 2 Describe instances $ euca-describe-instances Look on instace type. It must be ebs, but it is instance-store in the output. Note. If euca-describe-instance crashes on ebs instnce, apply https://review.openstack.org/#/c/95580/ ** Affects: nova Importance: Undecided Assignee: Feodor Tersin (ftersin) Status: New ** Changed in: nova Assignee: (unassigned) => Feodor Tersin (ftersin) -- You received this bug notification because you are a member of Yahoo!
