Package: vmdebootstra
Version: 0.5-1
Severity: important

Hi,

When following the usage example from vmdebootstrap(8), qemu fails to
boot an image if that image is a bit larger than 1GB and extlinux is
used. It just hangs at the SeaBIOS screen, whilst using 100% of a CPU
core, with the following message:

  "Booting from Hard Disk..."

Steps to reproduce:

  1073MB image is still OK (for me):
    $ sudo vmdebootstrap --image ok.img --size 1073M --owner=`whoami`
    $ qemu-system-x86_64 ./ok.img

  1074MB image, and larger, hangs:
    $ sudo vmdebootstrap --image hang.img --size 1074M --owner=`whoami`
    $ qemu-system-x86_64 ./hang.img

Using a separate /boot partition with eg --bootsize=50M did not resolve
the issue for me. Using --grub did, however.

I'm not sure who the culprit is: extlinux, vmdebootstrap, qemu,
qemu-utils, or seabios. Please reassign at will. In case this is an
extlinux limitation, though, then perhaps --grub should be forced with
size > 1g? I couldn't find any docs on that, however.

Regards,
Christian
