Summary: FreeBSD bootloader stops with BTX halted in hvm domU
Product: Xen
Version: 3.0.1
Platform: x86
OS/Version: FreeBSD
Status: NEW
Severity: major
Priority: P2
Component: Guest-OS
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: xen.nospam@xxxxxxxxxx
I am running Xen 3.0.2-2 with Ubuntu 5.10. VT hardware is a Pentium D 920
running on an Asus P5WDG2-WS (975X chipset).
I have tried several different versions of FreeBSD as hvm guests, all with a
similar result of BTX halted during the intitial bootloader process. One of
the versions tested was the FreeBSD 4.11 based m0n0wall, which would serve as a
nice lightweight test case. GRUB can be used to successfully boot the kernel,
although then drives are not detected instead giving an interrupt error. If
GRUB loads /boot/loader, a similar BTX halted error as described below occurs.
The error happens every time, in three different situations, so hopefully it is
easily reproducible. As noted before m0n0wall is an easy ~5 meg download and
should make for a nice test case <http://m0n0.ch/wall/>.
Thanks,
Andy

attempted as an hvm guest.
