Bug Description

First, I create a bootable volume with "cinder create --image-id $image_id--display_name=boot_volume --display_description "test bootable volume" 2".
What I expect: the image has been copied into the volume.
Then, I boot a VM from this volume with "nova boot --flavor 2 --block-device-mapping vda=$vol_id --security_groups=default VM_test".
What I expect: the VM should be successfully booted and in healthy state.
Result:

I am using the latest devstack and the OpenStack code under Ubuntu 12.04. The error disappeared, but there is a new problem.
1. glance image-list to retrieve the image-id.
2. Create a VM from the image: nova boot --flavor 2 --image $image-id --security_groups=default VM_test_from_image
The VM is running actively and I can ping it.

Then I tried booting from a volume.
1. Create a volume from the image: cinder create --image-id $image_id --display_name=boot_volume --display_description "test bootable volume" 2
2. Check the volume id: cinder list
2. Create a VM from the volume: nova boot --flavor 2 --block-device-mapping vda=$vol_id --security_groups=default VM_test
This VM is also running actively, but I cannot ping it.
