[9fans] recent Bell .iso images don't boot in QEMU

[9fans] recent Bell .iso images don't boot in QEMU

[Paul Ivanov]

Hey gang,

As per the subject, I tried to start playing with plan 9, but
kept running into this error:

    dosinit: can't open #S/sdC0/9fat dosinit #S/sdC0/9fat failed

and gives me a `Boot from:` prompt (which I have no idea what to do with)

My boot command was `kvm -cdrom plan9.iso -boot d  -hdc
Plan9.qcow2.img`. This is with

mischief on IRC suggested that I report this finding to the list.

I also saw the same error message trying to boot 9legacy.iso (but
perhaps that factoid should go to another list? forgive my
ignorance).

(I was finally able to get to Rio after getting a 9front.iso)

best,

This is a known issue in QEMU. It was introduced in QEMU 1.6.0
(August 2013). QEMU <= 1.5.3 are not affected.

I've submitted a patch in December:

http://lists.nongnu.org/archive/html/qemu-trivial/2013-12/msg00114.html

I believe the patch has been merged in the main repository,
so the current version from the Git repository should work.

Hopefully, the fix will be available as part of QEMU 1.7.1.

I ran into the same error on an OpenBSD machine (qemu version 1.7.0),
and obviously that error is a known problem.

However, I was able to boot and install the plan9.iso after moving the
cdrom to the slave of the disk's ide.

For me, that looked like:

qemu-system-x86_64 \
-drive file=9/Plan9.qcow2.img,if=ide,index=0,media=disk \
-drive file=9/plan9.iso,if=ide,index=1,media=cdrom -boot d

Hope that helps
