About the problem starting a XEN kernel OR the problem starting the normal kernel with hvmloader? Is this probably a kernel bug? And if so, where can I report it? Is it likely Xen is the problem or FreeBSD is the problem? Do I need more information than this? I can provide everything(even memory dump if that would help).

Hi, You can run (in theory) any FreeBSD on a hardware that has HVM support. You can check that with xm info. You can only run FreeBSD 8 as a PV guest with 32bit arch and hvm-pv with amd64.

See http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug-online-ddb.html for details on how to do this. I am a little confused. At the top of the output there is: GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb This makes me think that debugging is already compiled in. Also in the default XENHVM config option ddb and option kdb are already included. I had been seeing the db prompt. So I tried it again now.
