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
.........................................................................................................................

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.

Hubert,

Thanks for your feedback!  I'm impatient to try the Hurd myself 
:-)

I can help you with one thing, though:

you@probably ~$ ls -l /dev/kvm 
crw-rw---- 1 root kvm 10, 232 Apr  3 16:40 /dev/kvm

Add yourself to the ‘kvm’ group to use KVM as a regular user.

Kind regards,

T G-R

Hi Tobias,

Thank you for your answer...
I'll add myself in the 'kvm' group, thanks!

The Hurd is indeed so exciting; I was able to install Hurd K9 in 2004
(on real hardware, if I remember well). I keep a souvenir similar with
my first steps comparable to GuixSD...

It's seems to take a new dimension with Guix...

Good evening :-)

Hubert

Hello guix developers!  I just read this email thread from the
debian-hurd email list.  It looks like in the next few days the GNU/Hurd
bootstrap story will be simplified.  

https://lists.debian.org/debian-hurd/2020/04/msg00000.html

Also people not using the qwerty keyboard layout may be interested in
the "--curses" command from qemu, which starts the GNU/Hurd in your
keyboard layout of choice.  To the best of my knowledge the GNU/Hurd
supports many keyboard layouts but not keyboard variants like "dvorak".
Please note that starting the Hurd this way, will not allow you to start
X.  However, many Hurd developers code in the Hurd without X.  X is not
needed to code in the kernel for example...

I hope you paid attention to the output of that command.  :-)

Sorry, I wanted to give a feedback too fastly!

Here:
root@guix-system:~# guix install linux-libre
The following package will be installed:
    linux-libre

substitute: updating substitutes from 'https://ci-guix.gnu.org'... 100.0%
0,2 MB will be downloaded:
 /gnu/store/g70bhgkpr78i98iniiar4yw171f2h445-wishful-thinking

...
Help us achieve this dream!
We are really close to having a Guix System using the Hurd.
Join the discussion on IRC #guix on freenode.net and on the guix-devel@gnu.org
mailing list!

HTH
