GPU, USB, NICs and Other Physical Devices in Your Containers
summary
System containers using LXD expose real hardware without VT‑d: physical NICs, block devices, ZFS or Ceph volumes, and UNIX char devices show up inside containers and can be hot‑plugged. The demo attaches a physical NIC live, limits bandwidth, mounts /dev/sdX and a ZFS volume, passes /dev/kvm, and exposes two NVIDIA GPUs to multiple containers (CUDA benchmark runs and copies share the same cards). USB passthrough uses vendor/product IDs to attach a phone to adb; everything works without special firmware.
