When the xen_kernel is not used (removing xen_kernel and unloading the xen kernel in the bootloader) the sound comes just fine. I haven't used other audio outputs than dsp0 (headphones/speakers built in the laptop). - Running a PV domU guest causes the machine to reboot. I tried running the domU guest in the text console (I booted them machine wout X) to see if xen was able to throw me some debug, but nothing came out. Fully HVM domains do work fine (I have tried WindowsXP and FreeBSD 10.1 just fine). This is the machine dmesg: http://dpaste.com/0GED11W I carried my $work dockstation, which has a serial port on it. I also have another machine here, so I could debug the laptop via the serial port. A bit offtopic, but I'd like to ask if the xl toolstack has support for iscsi target disks. It would appear it is supported, according to this: http://wiki.xen.org/wiki/Tuning_Xen_for_Performance#Storage_options but I've been unable to find anything else about iscsi.
