On one of them there's simply no sound, on the other one sound is completely scrambled/distorted. I'm afraid this is going to take some time to solve, since I don't have any experience with audio devices. > - Running a PV domU guest causes the machine to reboot.

It would appear it is supported, according to this: > > http://wiki.xen.org/wiki/Tuning_Xen_for_Performance#Storage_options The iscsi support is only available for Linux Dom0, because the hotplug script is using the Linux iscsi tools. http://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=tools/hotplug/Linux/block-iscsi If you want you can copy it to tools/hotplug/FreeBSD and modify it in order to work for FreeBSD. I can try to take a look at it at some point, but my plate is quite full right now :(. Roger.
