Isn't it gfx_passthru=1
instead of gfx_passthrough=1? I believe your syntax is
wrong.
You right. That was misspelling.
What a joke man! I can only get Frank Lyon's NVIDIA Quadro
6000 VGA Passthrough completely 100% working but I cannot
get 100% success for my own display cards. I have been
trying a lot of things but still cannot get rid of the
yellow triangle with exclamation mark and error code 43.
Frank Lyon's NVIDIA Quadro 6000 costs S$6000++ and I can't
afford that.
There can be another problem why You cant pass thru vga.
The problem can be with Yours motherboard. You never wrote
what chipset You have and, I assume, You don't test Q6000 on
Yours MB. I have luck, cause even if nvidia's and Intel's
workers claims that chipset H67 don't have implemented
passthrough and I don't have any option in bios to turn it
on/off, then at least partially passthrough is implemented. If
You have possibilities to check this on different MB or put
Q6000 into Yours box then You will see if there is problem.
If You are willing we can try something. You can install
teamviewer on windows DomU and send me invitation or number by
email then I will inspect DomU and maybe I can help. We will
have possibilities to chat in teamviewer and You will control
everything.
