SR-IOV network

SR-IOV is a hardware standard that allows a single network card port to appear as several virtual network interfaces in a virtualized environment.

The sriov network type allows to specify presets to use when connecting instances to a parent interface. In this case, the instance NICs can simply set the network option to the network they connect to without knowing any of the underlying configuration details.

Configuration options

The following configuration key namespaces are currently supported for the sriov network type:

• user (free-form key/value for user metadata)

Note

Incus uses the CIDR notation where network subnet information is required, for example, 192.0.2.0/24 or 2001:db8::/32. This does not apply to cases where a single address is required, for example, local/remote addresses of tunnels, NAT addresses or specific addresses to apply to an instance.

The following configuration options are available for the sriov network type:

Key	Type	Condition	Default	Description
mtu	integer	-	-	The MTU of the new interface
parent	string	-	-	Parent interface to create sriov NICs on
vlan	integer	-	-	The VLAN ID to attach to
user.*	string	-	-	User-provided free-form key/value pairs
