[Bug 1470356] [NEW] AttributeError on creating instance with raw image type

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Nova compute raises AttributeError on creating the instance with raw
image type and instance goes in to error state.

Steps to reproduce:

1. Set image_type = raw in [libvirt] section of nova.conf and restart nova services.
2. Create an instance using image (I have used default cirros image).
$ nova boot --image 5e1659aa-6d38-44e8-aaa3-4217337436c0 --flavor 1 instance-1
3. Run $ nova list
4. Instance is in Error state and following error is logged in n-cpu logs
