Hi,
Sorry for the long message. I am not able to figure out a good
solution for the following:
Right now, what I do to test ports etc., is download install51.iso,
run it within qemu, and then do the work. To test the port on a
different server (which is on a different network), I end up burning a
new CD or use PXE boot within my LAN when that is possible, so that
the latest version is on a USB stick. However, I would like to have
-current or -beta on a USB drive without having to burn a CD or use
PXE boot.
Is it possible to install OpenBSD on a USB drive from within qemu and
then use that USB drive to boot a laptop?
For example, I installed 5.1 -beta as follows using qemu on my 5.0 desktop:
qemu-system-x86_64 -m 1024 -monitor stdio -no-fd-bootchk -hda
/dev/rsd6c -cdrom
home/vsankar/downloads/openbsd/jan27-2012/install51.iso -boot d
From my 5.0 desktop, I am able to do the following and boot OpenBSD
within a VM
sudo env ETHER=em0 qemu-system-x86_64 \
-m 1200 -no-fd-bootchk -hda /dev/rsd6c
I thought this would allow me to take the USB drive and boot from it
on my notebook. When it did not, I did a disklabel (on the qemu host
-- OpenBSD 5.0 amd64) and saw the following:
disklabel sd6
# /dev/rsd6c:
type: SCSI
disk: SCSI disk
label: DT 101 G2
duid: 0000000000000000
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 255
sectors/cylinder: 16065
cylinders: 973
total sectors: 15644912
boundstart: 0
boundend: 15644912
drivedata: 0
16 partitions:
# size offset fstype [fsize bsize cpg]
c: 15644912 0 unused
But when I boot the 5.1 VM, everything works from the USB and
disklabel shows all the partitions. Should I not see partition a
through k on the USB stick when using disklabel on the qemu host also?
I was expecting to see something like this from the qemu host as well
as the guest VM:
disklabel -A sd6
# /dev/rsd6c:
type: SCSI
disk: SCSI disk
label: DT 101 G2
duid: 0000000000000000
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 255
sectors/cylinder: 16065
cylinders: 973
total sectors: 15644912
boundstart: 0
boundend: 15644912
drivedata: 0

k: 2785728 12859040 4.2BSD 2048 16384 1 # /home
Any clues greatly appreciated.
Thanks very much,
