Public bug reported:
OpenStack liberty (Ubuntu 14.04)
When creating a new instance via the dashboard and selecting 'boot from
image (creates new volume)' the below is logged into nova-compute.log on
the host the instance is deployed to:
"Ignoring supplied device name: /dev/vda. Libvirt can't honour user-
supplied dev names"
In the virsh XML for the instance I can see the target dev name is sda,
this seems to have changed from how kilo was behaving.
I also noticed that if I then try and add an extra volume to this
instance the below error is placed in the nova-compute.log and the
volume is not attached.

Title:
Libvirt can't honour user-supplied dev names
Status in OpenStack Compute (nova):
New
Bug description:
OpenStack liberty (Ubuntu 14.04)
When creating a new instance via the dashboard and selecting 'boot
from image (creates new volume)' the below is logged into nova-
compute.log on the host the instance is deployed to:
"Ignoring supplied device name: /dev/vda. Libvirt can't honour user-
supplied dev names"
In the virsh XML for the instance I can see the target dev name is
sda, this seems to have changed from how kilo was behaving.
I also noticed that if I then try and add an extra volume to this
instance the below error is placed in the nova-compute.log and the
volume is not attached.
