Ensure that AMD-Vi/Intel VT-d is supported by the CPU and enabled in the BIOS settings. It is possible to make a virtual machine share the monitor, and optionally a keyboard and a mouse with a help of Looking Glass. It tries to pick a GPU by looking at PCI devices, not OpenGL renderers available in the system - the result is that Chromium may ignore the integrated GPU available for rendering and try to use the dedicated GPU bound to the vfio-pci driver, and unusable on the host system, regardless of whenever a guest virtual machine is running or not.

Logitech offers a keyboard in a full-size layout. For instance, in the example above, both the GPU in 06:00.0 and its audio controller in 6:00.1 belong to IOMMU group 13 and can only be passed together. Once you have a unifying receiver, the next step is to get it to recognize your existing mouse or keyboard. QEMU will continue to send key events to the PS2 devices until it detects the virtio input driver initialization. The windows iso and virtio driver iso should both be attached as regular SATA/IDE cdroms during the installation process. Follow the instructions. It can be calculated like this: The result must be rounded up to the nearest power of two, and since 25.82 is bigger than 16 we should choose 32. It is important to note that the K235 does not use a Unifying Receiver. Pairing is done to avoid interference from other radio frequency sources. Should this detection mechanism trigger, the drivers will refuse to run, resulting in a black screen. Not all PCI-E slots are the same.
