Feedback guix-hurd-20200401.img with qemu

[Hubert Lombard]

Hi Guix-devel :-)

From Linux gnu 5.4.30-gnu #1 SMP 1 x86_64 GNU/Linux

Yesterday, I had a try to test guix-hurd, here's my feedback, I don't know 
however if it can help...

$ guix environment --ad-hoc qemu -- qemu-system-i386 -enable-kvm -drive 
file=guix-hurd-20200401.img,cache=writeback -m 1G
.........................................................................................................................

         Automatically detecting the format is dangerous for raw images, write 
operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.

$ lsmod|grep kvm

kvm                   675840  1 kvm_intel
irqbypass              16384  1 kvm

With sudo:

$ sudo guix environment --ad-hoc qemu -- qemu-system-i386 -enable-kvm -drive 
file=guix-hurd-20200401.img,cache=writeback -m 1G

In this way, it works:

root@guix-system:~# hello
Hello, world!

root@guix-system:~# ls -l

    branch: master system! guix-system console
    commit: ef4b5f2f

root@guix-system:~# guix install linux-libre

(It has worked too)

Monday, on 6th April:

root@guix-system:~# adduser hubert

(OK)

hubert@guix-system:~$ startx

It seems to going well, but fails after showing an amorce of graphic
display.

(I can't see the first lines, but the following:)
