Comment 0 for bug 957622

I attempted to use kvm -kernel with a grub multiboot image, specifically grub-maverick-20100729.img at [1]. That file was built using [2]

$ url="http://bazaar.launchpad.net/~ubuntu-on-ec2/vmbuilder/automated-ec2-builds/download/head:/grubmaverick20100729-20100729071944-bevge631maio9jpl-2/grub-maverick-20100729.img"
$ wget $url -O grub-maverick-20100729.img
$ qemu-kvm create -f qcow2 disk.img 1G
$ kvm -curses -kernel grub-maverick-20100729.img -drive file=disk.img,if=virtio

This process works fine on oneiric and you will see a curses interface, and some output of grub looking for a image to boot.

On my laptop (with kvm support), I saw:

$ kvm -curses -kernel grub-maverick-20100729.img -drive file=disk.img,if=virtio;
fread() failed
$ echo $?
1

On a kvm guest (via openstack instance), it crashed differently:
$ kvm -curses -kernel grub-maverick-20100729.img -drive file=disk.img,if=virtio
Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory
Back to tcg accelerator.

GLib-ERROR **: /build/buildd/glib2.0-2.31.20/./glib/gmem.c:165: failed to allocate 4293918720 bytes
Trace/breakpoint trap (core dumped)

Just for a test, I tried loading kvm-amd, got nested kvm virtualization, but the instance fails the same way.
