Running linux as host and windows as guest with eGPU passthrough. My expectation is that internal to the CPU it is a PCIe device. To test if the Intel GPU works in passthrough, I needed to run an operating system that supported this GPU. Forum rules Before you post please read how to get help. Unbind GPU and HDMI audio drivers and bind vfio module to GPU while the system is running. Xen and KVM require different kernel arguments to enable PCI passthrough.
