Guten Abend,

seit dem Upgrade auf Proxmox Version 6.0 habe ich ein Problem mit meiner Grafik-VM.

Nach einigen Versuchen das Problem zu löschen, bin ich auf folgendes gestoßen.

Code:
First verify it works under Q35-3.1 machine type. If it does, try <ioapic driver='kvm'/> under <features>.
Q35-4.0 changed the default ioapic mode to split, which does not work with with certain hardware combinations.
I haven't thoroughly tracked this down but does not work with Ryzen+Nvidia at the very least.
This is not a new issue with split mode but it is an issue since machine type -4.0 changed the default mode.

Gibt es eine Möglichkeit wie ich den beschrieben Parameter per args in der VM-Config mitgeben kann?

Hey,
Ich hab ebenfalls das Update auf Version 6.0 gewagt. Leider hatte ich nach dem Update Probleme mit dem PCI Passthrough einer "Logic / Symbios Logic SAS2008" Karte in FreeNAS gehabt.
Meine momentane Lösung ist das manuelle setzen des machine Parameters in der Datei
/etc/pve/qemu-server/<VMID>.conf von:
Code:
machine: q35
auf:
Code:
machine: pc-q35-3.1
