PCI Passthrough
Donner à une machine virtuelle un accès direct et exclusif à un périphérique PCIe comme un GPU ou HBA.
With IOMMU enabled, hypervisors like Proxmox can pass a GPU to a VM for transcoding or gaming, or an HBA to a TrueNAS VM for direct disk control. The device is then unavailable to the host and other VMs.
