Hello,
today I tried qemu for the first time and I love it.
Now I'd need some speed and tried kqemu, but it immediately reboots my
machine.
Here is what I could transcribe:
Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 01
faulkt virtual address = 0x82
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc0670545
stack pointer = 0x28:0xe71e5a3c
frame pointer = 0x28:0xe71e5a50
code segment = bas 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 1461 (qemu)
[thread pid 1461 tid 100088]

Any help appreciated.
Thanks in advance,
