I tried at least SCSI and Virtio, which both didn't seem to work. I think I skipped SATA. Yes, with the same qemu command line as above, except if=scsi. The device's name will be /dev/da0 (SCSI/SATA) instead of /dev/ada0 (IDE). Here's a preseed file I just tested: http://pyro.eu.org/f/8Nwnc2CDTDKwtgi7VhsDrg.cfg partman is always slow, it does lots of probing and syncing; perhaps especially so with this virtual SCSI device; I get lots of these warnings from the kernel but they stop after filesystems are mounted: lsi_scsi: error: ORDERED queue not implemented GNU/kFreeBSD doesn't support virtio yet (upstream added it in the STABLE-9 branch and looks easy to backport post-wheezy.) VMware also has some special SCSI device that isn't supported. The default SCSI block device in Xen works okay for me. It's even faster if you rebuild with XENHVM kernel config (we may also want to build that as a new kernel flavour post-wheezy).

Actually I see this as a really convenient feature of the GRUB-based netinst images. It's very easy to add preseed and other options to the grub.cfg Another useful tweak is: kfreebsd $prefix/kfreebsd-9.gz kfreebsd $prefix/kfreebsd-9.gz -D to have kernel output copied to serial (so that with qemu -serial stdio this can all be logged). This includes segfaults, memory exhaustion or d-i's root ramdisk filling up, with the responsible pid + process name.

Hi Holger,

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!
