Type: infiniband

Note

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

Incus 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:

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

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

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

Device options

infiniband devices have the following device options:

Key	Type	Default	Required	Description
hwaddr	string	randomly assigned	no	The MAC address of the new interface (can be either the full 20-byte variant or the short 8-byte variant, which will only modify the last 8 bytes of the parent device)
mtu	integer	parent MTU	no	The MTU of the new interface
name	string	kernel assigned	no	The name of the interface inside the instance
nictype	string	-	yes	The device type (one of physical or sriov)
parent	string	-	yes	The name of the host device or bridge
