Type: infiniband

Supported instance types: container, VM
LXD supports two different kind of network types for InfiniBand devices:
physical
: Straight physical device pass-through from the host. The targeted device will vanish from the host and appear in the instance.sriov
: Passes a virtual function of an SR-IOV enabled physical network device into the instance.
Different network interface types have different additional properties, the current list is:

To create a physical
infiniband
device use:
lxc config device add <instance> <device-name> infiniband nictype=physical parent=<device>
SR-IOV with InfiniBand devices#
InfiniBand devices do support SR-IOV but in contrast to other SR-IOV enabled devices InfiniBand does not support dynamic device creation in SR-IOV mode. This means users need to pre-configure the number of virtual functions by configuring the corresponding kernel module.
To create a sriov
infiniband
device use:
lxc config device add <instance> <device-name> infiniband nictype=sriov parent=<sriov-enabled-device>
