video pass through, works great, until I restart the VM, then it just stops.

[sprockets2000]

Just like the title says, I can get video passthrough, works great, until I restart the VM, then it just stops.

 

I have read a few things I searched out about passing through a bios manually, tried that to disastrous results, I also tried recreating the VM with different BIOS (Q35)

 

 

Setup:

 

Core i5 2400

AsRock Z75 Pro 3

32GB DDR3 RAM

AMD Radeon R260X (Sapphire 2GB)

Windows 10 for the VM, though I have tried Windows 7 in the past

SSD - Cache

3Ware 9650SE Raid with 4 x 2TB WD Red in a raid 10 config

essentially adding the win10 fix to the <acpi> flag. For some strange reason I cannot update the acpi flag at all. I press update after changing it. and then edit xml, and what do you know? its back to the original... Very frustrating. Please help

 

 

The only temp fix i found is every time i wanna turn off the vm i have to delete it and paste a custom xml to a new vm using same vdisk. very frustrating process.

Thanks in advance

The problem is probably that you messed up the syntax.

Kvm is not supposed to be in the acpi tag. Acpi tag should look like this

 

<acpi/>
