Hi everyone,
Intro
I’m building a combo NAS, router & gaming HTPC based on a headless Ubuntu 20.04 using libvirt.
My problem
I’m struggling to make my GTX 770 work in my windows VM, the VM boots without issues, the graphics card is detected by the OS but the driver errors out with code 43.
I thought even for this old GPU that the driver lockdown was a thing of the past ?
What I tried
So I tried the basic counter measures of vendor_id and kvm hidden but no dice. And some more advanced ones.
Or with older drivers (but still more recent than R465)
I also tried to make it work with a ubuntu vm without success.
At this point I suspect that this error 43 is something else. To rule out hardware problems I succesfuly booted on windows and the GPU works as it should.
I don’t know where to look for troubleshooting.
All I find on the web are ways to bypass code 43 or to look for thermals. Not much info on where to look software wise to know what’s wrong.
So I’d be delighted to add whatever log or command output needed to troubleshoot this. Thank you very much
My hardware
Mobo : Asus X570F Gaming
CPU : Ryzen 5650G
RAM : 16G 3200 TridenZ RGB
GPU : MSI GTX 770
Storage :
2x HDD 160GO RAID 1 for the hypervisor root
2x HDD 8TO RAID 1 for the storage
Not in use at the moment
1x SSD 250GO that I will use passed through to the VM or as cache for the nas
2x HDD 2TO for backups and VM’s data
Also for the router end of things
4 port Gigabit PCIe NIC
WiFi N PCIe card
