When booting wheezy in an Integrity Virtual Machine on the zx6000, the VM crashes and dumps core - basically the VM equivalent of the red diagnostic leds that you see. I am also able to boot the squeeze kernel; it lacks storage drivers (those worked in 5.0.10, though...) but apart from that it looks good enough. On my VMs, I could not capture anything at all regarding what happens - either nothing is being spewed out, or I haven't found out where to get it. Serial at least doesn't show anything. If you find out anything more, I'm most interested. Regards, Lennert
