Hi Barry,

I filed a bug report here: When I
booted the virtual machine to add /var/log/system-image/client.log to
the bug report, /var/log/system-image/client.log didn't exist. Then I
couldn't reproduce the problem. I tried three times, each time with a
new copy of ubuntu-core-alpha-01.img.

If it happens again, I'll be sure to ping you on IRC. If you can think
of anything else I should try, please let me know. I'm happy to help.
