Réglage ProxMox

Sur le serveur hôte il faut activer activer la fonction DRM KMS du module NVidia :

proxmox:~# vi /etc/default/grub

...
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt intel_pstate=active nvidia-drm.modeset=1"
...

proxmox:~# update-grub

On redémarre le serveur.

Réglage LXC

Source Depuis le serveur hôte, avec pour exemple le conteneur 101 :

proxmox:~# vi /etc/pve/lxc/101.conf

...
lxc.mount.entry: /dev/dri/card1 dev/dri/card0 none bind,optional,create=file,mode=0666
lxc.cgroup2.devices.allow: c 226:1 rwm
lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.idmap: u 0 100000 65536
lxc.idmap: g 0 100000 44
lxc.idmap: g 44 44 1
lxc.idmap: g 45 100045 57
lxc.idmap: g 107 103 1
lxc.idmap: g 108 100108 65428

proxmox:~# vi /etc/subgid

...
root:44:1
root:103:1

Il faut démarrer ou redémarrer le conteneur et ajouter "root" aux groupes mappés :

lxc101:~# usermod --append --groups video,render root
lxc101:~# exec su -l $USER
