I have a system that I've booted using a live CD image (so
.../instance-<ID>/disk points at the ISO file). I've installed an OS
onto /dev/vda (which is .../instance-<ID>/disk.local).
Running 'nova image-create <INSTANCE> <NAME>` results in a traceback in
the compute log:
2012-08-16 09:48:56 TRACE nova.rpc.amqp ProcessExecutionError: Unexpected
error while running command.
2012-08-16 09:48:56 TRACE nova.rpc.amqp Command: qemu-img convert -f qcow2 -O
iso -s 6966cceec946407eb12531ddbe7bb7ac
/virt/pools/openstack_2/instance-0000004c/disk
/tmp/tmpMJ9GuL/6966cceec946407eb12531ddbe7bb7ac

2012-08-16 09:48:56 TRACE nova.rpc.amqp Stderr: "qemu-img: Unknown file
format 'iso'\n"
2012-08-16 09:48:56 TRACE nova.rpc.amqp
And the image gets stuck in the "SAVING" state:
# nova image-list
...
| f269eebc-d86e-4cd0-aacc-8b0c53fb3bb2 | cloud-f17-x86_64 |
SAVING | 4b3fccf9-28ab-4c29-acdb-cc5c18c862af |
Is there a way to do this properly? Obviously I can just munge around
in the filesystem to do what I want, but I was hoping for something
more convenient.
I guess another option would be...
- Boot from the live CD
- Create a new volume
- Attach the volume
- Install onto the volume
Is it possible to snapshot an ephemeral disk?
