PCI Device passthrough on Harvester

I want to share something that I’ve been working on for the last three months. Release 1.1.0-rc3 now has working PCI passthrough. Any PCI device in your cluster can now be passed through the hypervisor directly to a VM. This allows virtual machines to directly control a device, like a GPU, without any expensive virtualization layer in the way. In the diagram above, the guest (VM) has direct memory access to the host’s memory for the device.
