Hi all,
Just a quick post as a work in progress…
Now I know the first reply to this post will be something like, “Well it’s unsupported hardware…”. And I want to thank you in advance for all the help.
Ok, enough snarking for today.
I’ve noticed GPU passthrough issues with ESXI 6.7 when I had things working with 6.5+, and it seems others are seeing this as well.
I tried a couple different hosts with different NVIDIA cards (1030, 1080ti) and got the same results, after seeing the card initialize it would shut down/crash. From that point forward the dreaded error code 43 on device properties. I read many posts in the past that said 43 was an intentional disable in software when the driver detected it was running in a VM. So it got me thinking…
I always made sure that I had “hypervisor.cpuid.v0=FALSE” in my config before ever passing through the video card. But something changed in 6.7, or maybe Nvidia is looking for something else?
So I tried this:
Build a Windows10 VM (v1809)
don’t install vmware tools
install Chocolatey (https:chocolatey.org) For easier install of teamviewer and nvidia drivers
install teamviewer via chocolatey (so I can connect remotely) *also I didn’t have usb hardware that I could passthrough
Disable svga(vmware vga) adapter “svga.present=FALSE” in vm advanced config
set “hypervisor.cpuid.v0=FALSE”
Add 2 PCI devices: 1080TI, Audio Device
boot while simultaneously crossing fingers.
Ok so the start was not pretty as Windows detects the video card and you need to reboot after initial install and you don’t have vmware tools installed so its a cringe-worthy moment.
but alas after the reboot and the driver took, the output looked stable.
after that I installed the latest nvidia drivers via chocolatey (geforce-game-ready-driver) and all seems ok.
Quick testing with Cinebench and Unigine Superposition seems to work fine with a 1080p medium windowed score of 18390.
So, what was it? svga present? vmware tools?
If I had to guess it might be svga, because I saw a similar issue with Ubuntu 18.10. I was having problems getting the nvidia driver to work in Ubuntu so on a fluke I disabled the svga device and voila! Ubuntu 18.10 on a GPU!
I may install vmware tools and see if that makes a difference.
Anyways, I wanted to throw this out there for all the folks suffering with this issue. If it’s Nvidias doing then I suppose it’ll just be a matter of time for them to find another way.
