I upgraded my MB and dedicated GPU this week. Previously I was running fine with an AMD R7 but wanted to switch to an NVIDIA GTX 1060 I picked up. The overall MB switch went well, but I can't get the passthrough to work with the new GPU. I followed @gridrunner video and have captured my rom and edited my XML to reflect it. I've also pci-stubbed the new card in my syslinux file. 

 

I've attached my XML and my server log.

 

Any help would be appreciated.

In your motherboard bios did you activate VT-D ? 

What do you mean by not working? No display? VM crash? 

 

Those error message in the libvirt log are weird. It look like your issue might come from somewhere else. Try to make a new VM with only a VNC and look if those error are still there.
