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 )
   %base-services))


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

Host g64
HostName localhost
Port 
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.

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.

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

[[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

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.

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 - once you actually have control over your mouse, that is.

[Adonay Felipe Nogueira]

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. :)

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