Bug description:
  I saw this once before when I was less confident I knew how to run
  nova. I cannot reliably reproduce this problem. Here is the contents
  of the directory supposedly containng the missing file:

  root at xg11eth0:~# ls -l /var/lib/nova/instances/instance-00000001/
  total 82492
  prw-rw---- 1 root root        0 2011-10-21 16:21 console.fifo.in
  prw-rw---- 1 root root        0 2011-10-21 16:22 console.fifo.out
  -rw-rw-r-- 1 nova nova    65545 2011-10-21 16:22 console.ring
  -rw-r--r-- 1 root root 75497472 2011-10-21 16:26 disk
  -rw-r--r-- 1 root root 12582912 2011-10-21 16:22 disk.local
  -rw-rw-r-- 1 root root  4732048 2011-10-21 16:21 kernel
  -rw-rw-r-- 1 nova nova     1750 2011-10-21 16:31 libvirt.xml

  This was running from packages using oneiric-proposed
