Description Stefan Assmann 2009-06-17 05:58:49 EDT
Description of problem:
I tried to run the stock F11 kernel in kvm with
qemu-kvm -kernel /boot/vmlinuz-
but it didn't boot the kernel and only displayed:
FATAL: no bootable device.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. qemu-kvm -kernel /boot/vmlinuz-
Actual results:
FATAL: no bootable device.

Expected results:
boot of kernel vmlinuz-

Thanks, I can reproduced. It works with latest qemu-kvm.git/master
Comment 2 Daniel Berrange 2009-06-17 07:12:04 EDT
Historically when using  -kernel, it has been compulsory to add a IDE hard disk. This is because -kernel is implemented as a sick, disgusting, evil hack where we copy a fake boot sector into the first IDE hard drive, to make the BIOS boot the kernel specified. I think latest upstream has finally switched to using a proper option ROM to avoid this gross hack.
Comment 3 Stefan Assmann 2009-06-17 07:47:00 EDT
Hi Daniel,

my original idea was to do the following:

qemu-kvm -kernel /boot/vmlinuz- -initrd /boot/initrd- F11.img

and later on replace kernel and initrd with my custom builds for testing but that didn't work so I simplified it to realize that

qemu-kvm -kernel /boot/vmlinuz-

didn't work either.

If there is some other boot option to try just let me know.
