[SOLVED] run graphical app in systemd-nspawn

Hello Arch users !

I would like to run a proprio app in a minimal VM.
VirtualBox is too heavy.

I am trying to run it into systemd-nspawn but I am facing some difficulties because it is a graphical app.
I played with the following commands:

debootstrap --arch=amd64 stretch deb9
systemd-nspawn -D myContainer
passwd
logout
apt-get update
apt-get install xorg build-essential libgtk2.0-0 libnss3 libasound2 
apt-get install matlab-support

Then:

systemd-nspawn --bind-ro=/dev/dri --bind=/tmp/.X11-unix --bind=/opt/MATLAB/R2018a/ -b -D deb9
export DISPLAY=:0

I am able to install and boot the "guest" system but cannot launch the app.
Do you have any idea?

Many thanks!

Not an answer to your question, but rather a tangential suggestion;  If VirtualBox is too heavy, have you considered Qemu ?

What does "cannot launch the app" mean? Does it come with error messages?

...

P.S. If you get an error such as "could not connect to display :0" then you have probably failed to grant access via $XAUTHORITY or `xhost`, to your Xorg server.

That's not a solution, it's a work-around.

To run graphical applications from systemd-nspawn see http://forums.debian.net/viewtopic.php?f=16&t=129390

tl;dr:

# systemd-nspawn --directory=/var/lib/container/sid --setenv=DISPLAY=:0 --user=$user $application

Replace $user & $application with the appropriate values.
