Something Funky with Jails
To reproduce on yesterday's or today's M3 nightly: Make a freebsd jail by giving it a name. Next, try to make a VirtualBox jail. The template downloads but installation fails with "some error occurred". Try again and get message in error1.png. Try again with a different name and IP address, same error. Go to templates and note that the template has downloaded and has an Instances of 0.
Next, run warden list which shows two jails, one named freebsd and one named blah. Wait 5 minutes. Both jails magically show up in Jails. Try to make a third jail and watch the system reboot.
Can you reproduce?
