IRQ #16 (video card) disabled on vm passthrough

Hi!,

Im a newbie in Unraid so I apologize in advance if this post is not new, or correctly situated. Also, thanks in advance for the help!.

Im having problems with the video display on vms, when I start the computer the videocard is at irq 11, but when I fire up the VM it got changed to IRQ 16 and disabled, and the video wont start.

My hardware config is:

MSI z97 pcmate

i7 4790K

16Gb 2x8Gb ddr3 1600mhz.

MSI gamer gtx 970

I Know by fact (i checked on my new computer) that it shoud be painless... but is not!

So what I really want to know is:

If it is a hardware problem and I will have to change it to make it work, or it is some user error Im making.

Thanks again for the help!

JJ
