networking wont work in windows guest after gpu passthrough

I setup a vm and passed my graphics card through. My GPU works just fine but for some reason doing that disabled my internet connection in the guest. Ive created another vm without gpu passthrough and networking works just fine on it.

This could be a bug with the VM service you are using, and doesn't seem arch-related, unless we get more information.

Re: networking wont work in windows guest after gpu passthrough

I'm using qemu for my vm. Im also using a script that prevents the host from sleeping and my startup scripts disables a lot of things on my operating system while the guest is running. The guest has a network adapter for Ethernet, it just isn't receiving a network connection. Meaning it has to be an error with my host or one of my scripts interfering with my wifi connection on the host. I'm going to attempt to vnc on to the host while the guest is running to see if it is receiving a network connection at all. It might be a bug with QEMU but im not sure. Its a really strange error and definitely something that I didn't expect to happen.
