Can't boot via VNC or GPU pass through after update to 6.6.x

[Pin147]

Hello,

 

I have bought an old Q9400 CPU with Intel DQ45CB knowing that both support Vt-d to replace an E7200 CPU with the hope that I can create an Ubuntu and a Windows 10 machine for testing. For GPU, I have a Nvidia GT 730 from Gainward.

I have tried every combination possible: SeaBIOS, OVMF, Hyper-V enabled / disabled, different versions of Q35 and i440fx, I simply can't get a working VM via VNC or passthrough GPU. In BIOS Vt-d is enabled and the internal video adapter is set for the primary output.

 

If I get Ubuntu to boot and show something on the screen I get this (SeaBIOS, Q35 3.0, VNC). With OVMF there's only a black screen.

virtio1: virtio: device uses moern interface but does not have VIRTIO_F_VERSION_1

 

If I get Windows to boot with GPU passthrough (working only via SeaBIOS) I get only some white squares, after 2-3 seconds vertical lines followed by a black screen and that's it.

Via VNC I have no mouse and keyboard support. Tried also with VNC Viewer, the same thing, can't get the mouse and the keyboard working. Even if I assign them or not for VM.

 

I have watched all Spaceinvader One's videos on how to get GPU passthrough working. 

- Can't dump the bios with GPU-Z no matter what version I try, but found the same version on techpowerup, non-UEFI though. Even tried one with UEFI from another manufacturer with the same specs as my GT 730. Same output, white squares, vertical lines, black screen.

- Tried all PCIe ACS override options (Downstream, Multifunction, Both)

- VFIO allow unsafe interrupts: Yes (can't boot if it's set on NO)

 

GPU card is working. Tried it on another machine running Windows10. No problems.

 

This is the VM log from Ubuntu. Pretty much same output for Windows VM too.

And this is the libvirt log from VM Manager

I guess these errors should not be popping.

 

Could be something broken inside the OS or it's a hardware related problem not being compatible with Unraid?

 

Cheers

Same here since update to 6.6.0 or 6.6.1 with this CPU/MB.

Motherboard:Intel Corporation - DQ35JO

Processor:Intel® Core™2 Quad CPU Q6600 @ 2.40GHz

 

My VM Windows 7 and Ubuntu run fine on Unraid 5.5.3 but not boot since update. I trying to create a new VM with this same error VIRTIO_F_VERSION_1. I will follow this post.
