The physical ESXi host just assumes these type of USB devices are meant for it to consume. PCI passthrough to a VM is nothing new but passing through a USB keyboard/mouse also known as Human Interface Devices (HID) to a VM is generally not expected. In addition to a PCI passthrough of a GPU, they also wanted to passthrough independent USB keyboard and mouse to each individual VM. The customer that Darius was helping out had two VMs running on ESXi which they wanted to configure several passthrough devices. Funny enough, a couple of weeks after that conversation, a simliar issue was being faced by another customer and luckily I was able to share with them the solution and also validate the specific configuration that was needed. About a month back I had received an interesting tidbit from Darius Davis (VMware Engineer) after helping a customer solve an interesting problem and Darius thought this could be a useful blog post to share. ![]()
