SRC_BASE or SYSDIR respectively. - Add a few extra patches: [1] - An old patch by Enache Adrian to help NetBSD/OpenBSD guest support: http://lists.gnu.org/archive/html/qemu-devel/2007-11/msg00125.html (At least NetBSD still has issues seeing pci devices with acpi and assigning correct pci irqs without acpi when there still is an mptable which the qemu/kvm bios now defaults to providing, and it also doesn't seem to like most of the emulated nic choices - but these remaining issues have nothing to do with kqemu. I'll post a little more on the qemu-devel list...) - A patch series by Jan Kiszka from May 2009: http://lists.gnu.org/archive/html/qemu-devel/2009-05/msg01550.html In the unlikely case that any of these patches cause regressions please define WITHOUT_EXTRA_PATCHES and post details about your host _and_ guest on freebsd-emulation@freebsd.org .

Subject: [Qemu-devel] [PATCH 3/5] kqemu: Fix forbidden selector range change

Do not bail out on LDT selectors that match the reserved monitor GDT
|
|
selector range. At this chance, improve the related panic message.
