I'm not quite sure why the official Hydra gets a kernel panic in one of two VMs using the exact same kernels: https://hydra.nixos.org/build/26339384 Because the kernel panic happens before stage 1, let's wait for the first VM to boot up and after the bootup is done, start the second one in hope that it won't trigger the panic. Oddly enough, whenever I run the test on my own Hydra and on my local machines, I don't get anything like that. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
