Bug Description

I am trying to create/attach volumes using iSCSI on Xenserver. I followed the instructions here: http://docs.openstack.org/openstack-compute/admin/content/ch05s07.html#d5e579

When I run euca-attach-volume, I see the following trace in the nova-compute logs:

it was tested on an old revision of nova, but it looks like the implementation of volume_get_by_ec2_id that should be in /nova/db/sqlalchemy/api.py is no longer available.

This happens in the latest nova trunk also (revno 894)
