That would be wonderful, I've been working toward something like this.
Unfortunately I don't think the kernel/initrd/append options are
suitable for kfreebsd images.
Also note that kfreebsd install media use GRUB rather than
syslinux/isolinux.
I'd like to share a recipe that works for an extracted netboot.tar.gz:
$ qemu-system-x86_64 -m 512 -enable-kvm -net nic -net
user,bootfile=grub2pxe,tftp=. -serial stdio -boot n -drive
if=ide,bus=0,file=/dev/sdX,cache=writeback -no-reboot
(Of course, replace /dev/sdX with appropriate loop/block device etc. on
the host to use as a guest disk; cache=none may be even faster;
enable-kvm assumes a Linux host with kvm.ko installed+loaded).
I usually remove the font.pf2 file (forcing GRUB to run in text-mode)
and patch the grub.cfg like the attached. This automatically starts a
pre-seeded install, and the d-i syslog gets conveniently redirected to
qemu's stdout.
The preseed.cfg can probably be the same as a Linux one. If you specify
a partman-auto/disk it should probably be /dev/ada0 (first IDE whole
disk on kfreebsd-9) or /dev/ad0 (on kfreebsd-8).
Here's one I've had some success with:
http://pyro.eu.org/f/x-Lru4G5SieJVqMaRj71vQ.cfg
The above qemu command will show an SDL window (allowing easy manual
intervention if things go wrong) but for Jenkins I believe it needs
replacing with VNC.
It can be adapted easily to boot a mini.iso instead, but then it is
harder to tweak the grub.cfg.
Just let me know how else I can help with this.
Thanks!
