It’s also important to slot the GPU into the proper PCIe slot on your motherboard. If the GPU is attached to the PCIe socket that has the same IOMMU group as the M.2 SSD, SATA controller, Ethernet jack, or other similar devices, attempting to passthrough the graphics card to a VM c...
For notes on how to troubleshoot or verify if IOMMU is working as intended, please see theVerifying IOMMU Parameterssection in our wiki. It is also important that the device(s) you want to pass through are in aseparateIOMMUgroup. This can be checked with a call to the Proxmox VE API: ...
and get applied, but when you then try to start the VM, it sees that IOMMU group 1 is already connected to your NAS VM (since you pass through the SAS controller which is in the same group), and thus fails to use the WiFi card - since the same group *cannot* be connected to two...
IOMMU is not enabled (because it is all in one group *). Check with cat /proc/cmdline whether intel_iommu=on is actually there. If that's the case then it's a motherboard/BIOS issue. If it is not there, then maybe you are booting in UEFI mode with ZFS or you did not run upda...
options vfio_iommu_type1 allow_unsafe_interrupts=1 Once you’re done, you mustupdate the initramfs of your Proxmox VE server. What to do if my GPU (or PCI/PCIE Device) is not in its own IOMMU Group? If your server has multiple PCI/PCIE slots, you can move the GPU to a different ...
