My VNC console suddenly broke after working perfectly for several days.

The supervisor log shows:

It appears to have been a permissions issue, but I have no idea how or why. ;)

Re-running chown -R www-data: /path/to/webvirt fixed the issue.

Hmm...not a permissions issue. I set up a second machine identically (using puppet) and I am getting the same message. Changing permissions and restarting the service had no effect.
