With new enough hardware, or if you don't mind the security risks with older hardware where iommu was incomplete and could allow a malicious guest to take over the host, it is indeed possible with KVM to pass through raw PCI or USB host devices so that the host no longer touches the device, and the guest manipulates the device directly. Are you using virsh, virt-manager, or some other means to manipulate your guest definition? Depending on that answer determines how you would add a host-device passthrough to your guest. -- Eric Blake [email protected] +1-919-301-3266 Libvirt virtualization library http://libvirt.org
