Bonjour
sous proxmox -à base de Debian- je fais tourner des VM sous Monterey
ou Sonoma, Sequoia devrait également être possible.
Bonjour,
Merci pour ta réponse.
Je recherche des infos sur la possibilité pour l'os virtualisé
d'accéder à la carte graphique.
Les infos convergent vers GPU passtrough
---------------------------------------------------------------------
« GPU passtrough e.g single pcie gpu per vm is the best option
performance wise. It will give you 99% native gpu performance. However
for that to work you need modern hardware with vt-d support !
Otherwise you can use virtio gpu acceleration and share the gpu with
all your vm's, this will allow you to use hardware acceleration for
software that makes use of it. But It has quite some overhead. For
normal desktop use its fine. For rendering / games i would go with a
dedicated gpu.
You dont need a gpu at all, proxmox can virtualize it if you just need
rdp/vnc. »
---------------------------------------------------------------------
Par contre la poste suivant m'interpelle :
« In addition to @H4R0, if you want to virtualize desktop operating
system with GPU stuff, best is to use a desktop virtualizer like
VirtualBox or VMware Workstation. Performance is much better there.»

VirtualBox, aurait de meilleurs performances graphiques que
proxmox(KVM et LXC) ?
