Hallo zusammen!

Bevor ich hier in aller Ausführlichkeit schreibe, was ich schon alles probiert habe, möchte ich nur eine kurze Frage stellen.

Ich habe eine Intel CPU mit Onboard-Grafik (00:02.0 VGA compatible controller: Intel Corporation GeminiLake [UHD Graphics 605] (rev 03)) und möchte sie zu einem LXC-Container durchschleifen (Passthrough). Und so langsam dämmert mir, dass das gar nicht funktionieren kann, weil ich nur diese eine Grafikkarte habe. Also keine dedizierte. Auf dem Proxmox Host wird mein angeschlossener Monitor erkannt. Auf dem LXC nicht. Wie kann ich Proxmox den Monitor "wegnehmen", und dem LXC zuweisen?

Das sind die Ausgaben von
Bash:
get-edid | parse-edid

Auf Proxmox:

Bash:

Problem requesting slave address: Device or resource busy

Looks like i2c was successful. Have a good day.

Und auf dem LXC:

Looks like no busses have an EDID. Sorry!
Attempting to use the classical VBE interface
mmap /dev/zero: Operation not permitted
error initialising realmode interface
do you have full superuser (root) permissions?
I'm sorry nothing was successful. Maybe try some other arguments
if you played with them, or send an email to Matthew Kern <pyrophobicman@gmail.com>.
