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.

Device options

infiniband devices have the following device options:

hwaddr

MAC address of the new interface

Key:	hwaddr
Type:	string
Default:	randomly assigned
Required:	no

You can specify either the full 20-byte variant or the short 8-byte variant (which will modify only the last 8 bytes of the parent device).

mtu

MTU of the new interface

Key:	mtu
Type:	integer
Default:	parent MTU
Required:	no

name

Name of the interface inside the instance

Key:	name
Type:	string
Default:	kernel assigned
Required:	no

nictype

Device type

Key:	nictype
Type:	string
Required:	yes

Possible values are physical and sriov.

parent

The name of the host device or bridge

Key:	parent
Type:	string
Required:	yes

Configuration examples

Add a physical infiniband device to an instance:

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

Add an sriov infiniband device to an instance:

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