The stoney cloud contains drivers needed to run in a virtualized environment, namely Qemu/KVM, but the initial ramdisk does not load them automatically. Therefore some manual work is needed to successfully boot a fresh installation inside Qemu/KVM.

Before finishing the installation

When being asked Do you want to reboot your system? switch to a second console (Alt + F2) and execute:

vim /mnt/osbd/boot/grub/grub.conf

Append the following to the two lines starting with "kernel":

doload=virtio_pci,virtio_blk

This will make sure that the initial ramdisk loads the required virtio-drivers during boot.

Afterwards switch back to the installer (Alt + F1) and answer yes.

After having finished the installation

Even if you already finished the installation and rebooted, there is a way to boot your installation:

When you get the GRUB boot screen:

  • press e on the already selected boot line
  • use the arrow keys to navigate to the entry starting with kernel /kernel ... and press e again
  • append the following to the line: doload=virtio_pci,virtio_blk
  • press ESC to exit and then b to boot

This change can be made permanent by logging in as root after the startup and editing the grub configuration:

mount /boot
vim /mnt/osbd/boot/grub/grub.conf

Append the following to the two lines starting with "kernel":

doload=virtio_pci,virtio_blk
