Hello, Debian Squeeze 6.0.1a worked perfectly for me. Regarding the submission of bugs, I would like to extract the kernel log from the Ubuntu HVM (because I can boot to the LiveCD), but since I have no network or hard drive this is kind of complicated. I will try to attach a USB drive or something, so I can make a dump there. Suggestions about how to save this trace are welcome.
