http://www.openmirage.org/wiki/xen-boot) and after tweaking the script slightly, I'm able to bundle, unload, and boot up and ec2 instance with a mirage kernel. The instance launches just fine and I can see output from various mirage systems in the ec2 system log output. However, when I try to connect to my ec2 host (after opening port 80 in the ec2 console), my web browser just hangs.
