I was curious today and tried the FreeBSD-amd64 install iso in qemu,
qemu-system-x86_64 -m 256 -monitor stdio -cdrom
5.3-RELEASE-amd64-bootonly.iso -boot d
and, (actually i tried miniinst first, but bootonly is smaller and shows
the same result) qemu hangs when starting the kernel, the monitor does not
respond, all I can do is ^c it. (the started kernel is supposed to print
messages starting with the copyright but it doesnt even get to that.)
So, question: what does it mean when the monitor doesnt respond?
infinite loop in the translated code?
Well, i just tried it in gdb and this is what i get when ^c'ing it:
Program received signal SIGINT, Interrupt.
[Switching to Thread 1077076096 (LWP 18901)]
0x080f00ee in do_interrupt64 (intno=13, is_int=0, error_code=0,
next_eip=4626569007820963840, is_hw=0) at softmmu_header.h:237
237 {
(gdb) bt

(gdb)
so its processing interrupts apparently, but why does that `hang' qemu?
mirrors for bootonly and the other isos can be found here:
http://mirrorlist.freebsd.org/
for example:
ftp://ftp.fr.freebsd.org/pub/FreeBSD/releases/amd64/ISO-IMAGES/5.3/
(bootonly is some 20M, the others are larger)
