Comment 0 for bug 879666

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@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
