Description Jan ONDREJ 2009-05-07 11:58:07 UTC

Description of problem:
After I was able to boot my guest as described in bz#499596, my guest fails again at startup. Changing drive interface from virtio to ide helps to boot.

Version-Release number of selected component (if applicable):
qemu-0.10-16.fc11.i586
kernel-2.6.29.2-126.fc11.i586

How reproducible:
always for me

Steps to Reproduce:
1. follow steps in https://bugzilla.redhat.com/show_bug.cgi?id=499596
2. run /usr/bin/qemu-kvm -cpu qemu32 -boot c -drive file=rawhide.img,if=virtio,index=0,boot=on -serial stdio

Actual results:
Initalizing network drop monitor service
Freeing unused kernel memory: 436k freed
Write protecting the kernel read-only data: 1460k
Mounting proc filesystem
Mounting sysfs filesystem
Creating /dev
Creating initial device nodes
input: ImExPS/2 Generic Explorer Mouse as /devices/platform/i8042/serio1/input/input3

Nothing else on serial console.

Expected results:
booted system

As glommer points out, this could be an extboot issue - with IDE, if extboot fails then boot can still succeed, but this is not true for virtio

Also, note that this is a 32 bit host

Comment 2 Glauber Costa 2009-05-07 12:09:18 UTC

After looking at the bug report in details, it is probably _not_ an extboot
related issue. extboot only serves the purpose of booting the system. It seems this step is passed for this guy.

Comment 7 Glauber Costa 2009-05-19 01:29:52 UTC

Does this still happen ?

Comment 8 Jan ONDREJ 2009-05-19 10:08:52 UTC

Yes, still problem with qemu-0.10.4-5.fc11.i586.

Comment 9 Mark McLoughlin 2009-06-04 11:26:57 UTC

Could you boot the guest in qemu and confirm that the initrd.img in /boot has the virtio drivers included?

  $> gzip -cd < /boot/initrd...img | cpio -ivt --quiet | grep virtio

I think you installed without virtio originally, which would explain it.

To fix that, you just need to run e.g.

  $> mkinitrd --with virtio_pci --with virtio_blk -f \
              /boot/initrd-$(uname -r).img $(uname -r)

Resulted with no output.

I think this was broken when I updated my kernel without virtio driver, because virtio was not functional for me in previous releases.

Todays installation of Leonidas worked well.

This also fixed my problem.

You can close this bug too.
