PCI and USB Device Passthrough

Hypervisor Assets lets you define PCI or USB devices on a host - GPUs, USB controllers, and similar hardware - and attach them directly to a VPS for genuine device passthrough, not a virtualized/shared equivalent.

Adding an asset includes a live IOMMU group scan of the host, so you can find the correct PCI address for the device you actually want to pass through rather than guessing at lspci output by hand. Your host's IOMMU (VT-d/AMD-Vi) must be enabled in BIOS and the kernel for any of this to work at all - passthrough itself needs real hardware IOMMU support, there's no software fallback.

Attaching a device to a VPS restarts it (a passthrough device has to be present when the guest starts, it can't be hot-added the way network config changes can) and marks that VPS as ineligible for live migration, since the physical device it's now tied to only exists on this one host.

Detach a device from the VPS's own page to release it back to the available pool for another guest to use.
