trying to enable igpu passthrough - dmesg showing the following

[therealivandrago]

Hi,

Been following the following 2 guides and I cannot get igpu to passthrough to my linux VMs. Tried with a fresh debian install and a fresh ubuntu server install everytime i enable add the pci device using hardware > add > pci device > raw device > uhd 630 (intel i3-10305) the power on the virtual machine it crashes.

The cpu supports vt-d and vt-x according to intels site.

https://192.168.x.x:8006/pve-docs/chapter-qm.html#qm_pci_passthrough
https://pve.proxmox.com/wiki/PCI_Passthrough

I then started checking the verifying IOMMU part of the wiki and got a crap ton of errors below running

dmesg

. The other dmesg with grep command above it just returns nothing.

virtualization options are also enabled in the motherboard settings. strangely running intel_iommu=on or iommu=pt return nothing and do not reflect within /etc/default/grub

Hardware

• i3-10305
• AsRock H510M-HDV
• 32GB g.skill ripjaws F4-3600C18D-32GVW

whoops, looks like i had only enabled VT-d in the BIOS and forgot to turn on SR-IOV (not realizing the igpu uses pci) and SR-IOV is needed to allow virtualization for PCI devices.
