GuixSD in a VM is so nice - once you actually have control over your mouse, that is.

GuixSD in a VM is so nice - once you actually have control over your mouse, that is.

[Fox]

so I run GuixSD (on bare metal nicely and) on qemu

but mouse capture is an issue in that gpm or whatever runs the mouse.

I "can't come back from the Immelmann loop" , so-to-speak. The only 
"ESCAPE" is CTRL-ALT-F3  with root login and "reboot".


I mean ... these days a VM should maybe be fine with mice of 21st. 
century design or am I going down a wrong alley ?

it could be delay   somewhat long    before Guixers are notified of the 
ESCAPE keypresses. I'll investigate.

I don't know what is the issue exactly, but from the QEMU documentation
I can see that, in order for it to grab or release mouse and keyboard,
one has to press Ctrl + Alt.

Lastly, strangely enough, I as a non-tech user understand QEMU as a
VM. But of course, no non-tech user's opinion replaces thechnical
ones. :)

GuixSD in a VM is so nice

[Fox]

indeed:   just press CTRL-ALT    (Strg-Alt in places)

too bad, notification about this does not show up in time in the QEMU 
window titlebar seemingly. well well, we saw harder challenges.

Re: GuixSD in a VM is so nice

[Adonay Felipe Nogueira]

I'm glad that we got this sorted out. :)


Happy hacking! :)

indeed, now I need to find out why vlan0 is dead in qemu.
qemu-x86 -net default
is a no-workie. I will report back on this.   :)

Re: GuixSD in a VM is so nice

[Adonay Felipe Nogueira]

I don't know if this is right, but at least according to
[[https://qemu.weilnetz.de/doc/qemu-doc.html#Network-options]], I see no
way to tell `-net default` to QEMU.

yeah but the GuixSD install manual uses it,
https://www.gnu.org/software/guix/manual/html_node/Installing-GuixSD-in-a-VM.html#Installing-GuixSD-in-a-VM
so somebody must have gotten it to work presumably.

Re: GuixSD in a VM is so nice

http://wiki.qemu.org/Documentation/Networking

So helpful that the "notes" tell you a problem but hardly the solution.
Seems I ran into a common problem.

Re: GuixSD in a VM is so nice

[Adonay Felipe Nogueira]

The documentation section (the reference I gave earliear), not the wiki
page (the reference you just gave), tells the solution for the problem
described in the wiki page. The wiki page also mentions the solution but
it's implicit. That wiki page tells you that you have to provide options
that identify the host's network in order for the QEMU system to make
use of it.

Re: GuixSD in virtualbox

[Fox]

installing GuixSD in a virtualbox is much less hassle and it runs 
noticably faster than on qemu.


  dhclient enp0s3

got network running here

Re: GuixSD in virtualbox

[Adonay Felipe Nogueira]

You might want to make sure that the version of VirtualBox that you have
is fully free/libre though.

The current versions of it, as far as I know, aren't, so I think Guix
should avoid recommending it.

Specifically, VirtualBox relies on a non-free toolchain at build time,
AIUI.  That’s why Guix does not include it.

Fox: QEMU should run about as fast as native code as long as you provide
the ‘-enable-kvm’ command-line option.  See
<https://www.gnu.org/software/guix/manual/html_node/Running-GuixSD-in-a-VM.html>.

HTH,

Thx I had found that kvm info too.

Sadly GuixSD suffers breakdown after the install of python for some 
weird reason.

My idea was to do GUI programming stuff with guile-gnome-platform 
available also on NixOS and as a NixOS package.
But to get the hello-world going requires quite some effort, I found.
And my NixOS install went haywire after only a few hours.

Meanwhile I found the Mr.Ed GUI-designer for Dr.Racket-GUI (racket 
scheme) which gets you started way faster.
https://pkgs.racket-lang.org/package/mred-designer
seems more useable than Boa-Constructor even.

Maybe I drop guile in favour of racket hence. running WxGlade LISP code 
with guile seems quirky too.

Re: GuixSD in virtualbox

Which break down is related to GuixSD and Python?

Please tell us so that we can help out.

Thx, I repeatedly restarted the

guix system init /mnt/etc/config.scm /mnt


line which broke during python2.7 install repeatedly.

After 3 hrs I kinda gave up on it. Maybe it just has been network 
overload, I will try again in the vbox image if I find a cool app to run 
in GuixSD such as scsh or shepherd of course. Also NixOS kinda let me 
down even though the nix package manager under debian never gave me much 
if any trouble. I'll report back if I could continue later a successful



guix system init /mnt/etc/config.scm /mnt


lispy greetz!

As others already pointed out, "Ctrl-Alt" is the way to get out of the
cage.

Mostly I don't use the VM-Window: I had some trouble with gpm and don't
know how to enable clipboard-sharing in QEMU, so I just use SSH:

My GuixSD-QEMU-Configuration has something like:

 (services (cons* 
		... other services here ...
                (dhcp-client-service)
                (lsh-service #:port-number 3333)
                   %base-services))


Then in my host system I have an entry in my ~/.ssh/config:

Host g64
        HostName localhost
        Port 3333
        User bjoern


When I now call "ssh g64" and enter my password, I'm connected to my
virtual machine and can use the normal mouse and copy/paste of my host
system as I would use with other remote machines.

You can also upload your SSH-Key in your virtual machine to avoid
password entering.

And probably when I would setup a new VM, I would use OpenSSH
(https://www.gnu.org/software/guix/manual/guix.html#index-openssh_002dservice_002dtype),
but when I started with my setup, there was only LSH.
