GPU (Radeon) and SAS-Controller Passthrough not possible at the same time

mcflym · Jan 19, 2020

Hi,

my setup:

Proxmox: 6.1-5

Board: Supermicro x10sl7-f with Xeon 1230v3

GPU: Radeon 5500 XT --> GPU-VM
SAS-Controller: Onboard --> Storage-VM

GPU-VM is Windows 10
Storage-VM is debian

I can't use both pcie devices at the same time. After a while the GPU-VM is going into suspended mode in proxmox. If I resume the VM - it stopps. If I then start the VM again, the GPU gets code 43 inside the VM. The Storage-VM is doing fine the whole time.

If I only use the GPU-VM the GPU-VM works fine.

Any ideas? Thank you in advance!

Here are my settings:

Could you resolve this?

Did you try the GPU passthrough alone?

Any message in the logs?
