Type: infiniband

Note

The infiniband device type is supported for both containers and VMs. It supports hotplugging only for containers, not for VMs.

LXD supports two different kinds of network types for InfiniBand devices:

  • physical: Passes a physical device from the host through to the instance. 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.

    Note

    InfiniBand devices support SR-IOV, but in contrast to other SR-IOV-enabled devices, InfiniBand does not support dynamic device creation in SR-IOV mode. Therefore, you must pre-configure the number of virtual functions by configuring the corresponding kernel module.

To create a physical infiniband device, use the following command:

lxc config device add <instance_name> <device_name> infiniband nictype=physical parent=<device>

To create an sriov infiniband device, use the following command:

lxc config device add <instance_name> <device_name> infiniband nictype=sriov parent=<sriov_enabled_device>

Device options
