nova-compute is missing dependency on qemu-kvm

[Scott Moser]

after installing nova-compute-lxc and attempting to run an instance i got:

2011-08-25 05:35:53,595 DEBUG nova.utils [-] Running cmd (subprocess): qemu-img create -f qcow2 -o cluster_size=2M,backing_file=/var/lib/nova/instances/_base/da4b9237bacccdf19c0760cab7aec4a8359010b0 /var/lib/nova/instances/instance-00000003/disk from (pid=805) execute /usr/lib/pymodules/python2.7/nova/utils.py:164

(nova.exception): TRACE: OSError: [Errno 2] No such file or directory

The missing executable was 'qemu-img'

nova-compute in lxc mode uses qemu-img and qemu-nbd from qemu-kvm package.

I realized this also not listed as a depends of nova-compute, and I think the dependency is probably there.

It would seem the best solution would be for the ubuntu qemu-kvm source package to create a qemu-utils package like debian's.

I opened bug 833799 as a feature request for qemu-kvm package to build a qemu-utils package.

This bug was fixed in the package nova - 2011.3~rc~20110901.1523-0ubuntu1

---------------
nova (2011.3~rc~20110901.1523-0ubuntu1) oneiric; urgency=low

  [ Chuck Short ]
  * Really remove python-ipy.
  * New upstream release.
  * Use "--use_deprecated_auth" by default because we dont support
    kestone yet. (LP: #838768)

  [ James E. Blair ]
  * Add python-unittest2 as a build dep.

  [ Dave Walker (Daviey) ]
  * debian/control: Added python-kombu as a build and run depends.
    - LP: #798876

  [ Scott Moser ]
  * add dependency on qemu-kvm to nova-compute (LP: #833530)
