GuixSD in a kvm

GuixSD in a kvm

[Christian Thaeter]

I am trying to get GSD running inside a kvm (debian jessy, with a
vanilla 4,0 kernel) but having problems to boot the system.

The system configuration is pretty much the same as from the example,
just changed username, filesystem label and type to ext4.

I've used 'gsd-usb-install-0.8.1.x86_64-linux' for installation.

The first try failed, when rebooting the kernel can't be found.

  http://public.pipapo.org/guixboot.png (sorry, no c'n'paste from the
  vm)

investigating the case from the grub commandline reveals that grub is
unable to read the /gnu/store

This seems to be a problem with the emulated SATA disk.

When reconfiguring the disk to IDE or Virtio it starts booting but ends
up in a kernel panic

killing init? wtf.... anyone has an idea what could be going wrong
there?

The initrd script threw an error, thus you get a kernel panic.  The
errors in that screenshot show that the initrd couldn't write to
/etc/group when creating your user account, which caused a later call to
'getpw' to fail.

I'm afraid I don't have any ideas of what to try next.  Anyone else?

Yay, i've now installed a basic debian, build guix from source, did a
guix pull, then system init on another virtual drive and booting into
that. IT WORKS!

I have no clue what the error was with the usb-install image, tough.
Well now I can start playing with GuixSD.

I think the problem is that there’s a stale /etc/group.lock file (this
is what ‘groupadd’ reports.)

Christian: could you try to remove that file (you may need to access the
partition from another system, for example) and reboot?

We shouldn’t be ignoring groupadd’s return value, but there’s nothing
sane we can do, is there?

Thanks,
Ludo’.
