Installer Test Server in the E19-741 server room is an automated installer testing server. Every day it installs a VM from each of production, proposed, and testing. It zephyrs its results to -c debathena. logs are in /home/tester, and the logs will contain the path to the VM image for debugging. You can mount the .img file (see in root's homedir) as you would any QEMU disk image, and examine it.

debathena-root is on the .k5login for root.
