bug#29934: in virtual machines the graphical dektop environment randomly fails to show up

[Catonano]

[-- Attachment #1: Type: text/plain, Size: 423 bytes --]

I created a virtual machine with this command

./pre-inst-env guix system vm ~/configs/vm-config-desktop.scm \
   --image-size=10GB \
   --expose=$HOME \
   --share=$HOME/tmp=/exchange

I run this virtual machine with this command

/gnu/store/zlnjsjgw8d0b6p1p7c3dbh4g6x80mrq6-run-vm.sh

Sometimes the graphical login screen comes up

Sometimes it doesn't and a login form in a terminal gets proposed

This happens randomly

[Danny Milosavljevic]

Can you try to make it not show up and then check the log files in the guest?

Also, how does vm-config-desktop.scm look?

This is the vm-config-desktop.scm file
https://paste.freshbakedyams.com/paste/J93D5MQD

As for the log in the guest, how wold I copy and paste it ?

There's a stdio feature in qemu:

qemu-system-x86_64 -enable-kvm -hda Q -serial stdio -m 1G
                                      ^^^^^^^^^^^^^

So if you start qemu in a terminal, you can log into the guest from that terminal (at least when you pass (kernel-arguments '("console=ttyS0")) to the guest.

You can copy & paste normally from that terminal.

It says:
qemu-system-x86_64: -hda Q: Could not open 'Q': No such file or directory

This is the ffile that I'm using to launch quemu

Yeah, so this one has already the "-serial stdio" option.  And it also has the console=ttyS0 option.

So just run the VM from a terminal, it should print output and accept input in the terminal.

Oh sorry, you edited it, right? Then remove the -hda Q, it's just an example.  Just the -serial stdio and kernel option is enough.

This is the new version of the command to launch qemu

What happens now is that it hangs on:

Booting from ROM...

No, sorry, I think I used the wrong script

Now it works

Sometimes I need some pauses, I get tired. I apologize

So, this is what I could fetch in the terminal (cool trick ! Thhanks !)

You said that I could have logged in from the host terminal, right ?

How do I do that ?

The host terminal is running qemu, there are the messages that I'm pasting
here, no prompt

Please bear with me

bug#29934: in virtual machines the graphical dektop environment randomly fails to show up

[Danny Milosavljevic]

Hmm, does it work when you don't expose $HOME ?

Maybe X dislikes multiple concurrent users of its Xauthority files.

Then no getty is running.

Please add 

    (mingetty-service-type config =>
                           (mingetty-configuration
                            (inherit config)
                            (tty "/dev/ttyS0")))))

to (services ...) in vm-config-desktop.scm .

Maybe agetty instead of mingetty, I forgot...

That should start a login thingie on the serial.

Good news !

adding the mingetty service I get this

<unknown location>: error: invalid field specifier

when calling guix system vm

Also, I fiddled with the mingetty service line, to no good

I read here that mingetty should be in the %base-services ?

https://www.gnu.org/software/guix/manual/htmlhttps://www.gnu.org/software/guix/manual/html_node/Base-Services.html#Base-Services_node/Base-Services.html#Base-Services

Anyway, I tried without --expose=$HOME \ and it works

catonano CAN log in, now

There's a shocking amount of warnings and erros, missing resources and so
on, in fact the resulting desktop is somewhat awkward (blu background, no
picture)

BUT it works

I opened the file browser (Nautilus ?) and the utility to visualize the
disk utilization

I'd say that the session is viable

I don't now why, as I don't understand the X layers stack, and I don't
understand qemu.
Which 2 users accessing the .Xauthority file ?
And what is this .Xauthority file useful for, anyway ?

But I'm satisfied nonetheless.

I want to use a virtual machine to test my Trytond service and Tryton has a
native GUI client so a graphical environment is necessary

I could connect a client running in the host to the sevice running in a so
called headless guest but I see this line, when I launch qemu

Warning: vlan 0 is not connected to host network

so I'm not sure I want to go there

Thank you Andy, I know I strained your patience
I appreciate that 🙏

Ciao
