Bug Description

I wish to create a instance with local disk(1G) and attaching a blank(new created) volume(2G).

using follow nova command line api, but I specify the bdm's device=vda

nova --debug boot --image baaece45-58a2-4e4c-b8b7-7b3f12fe4bc6 --flavor 1 --nic net-id=9af3d913-dd65-4864-88b5-cd42bce3f672 --block-device source=blank,dest=volume,device=vda,size=2 test12

I got a instance , by checking domain xml
I only got 1 block device(2G), but no local disk was created.

============
expect result.
1. raise badrequest if sepcify device=vda in block-device.
or
2. just ignore device=vda in block-device and create 2 device for this instance.

I prefer option 1.
