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:

maas (MAAS network identification)
user (free-form key/value for user metadata)

Note

LXD 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
`maas.subnet.ipv4`	string	IPv4 address	-	MAAS IPv4 subnet to register instances in (when using `network` property on NIC)
`maas.subnet.ipv6`	string	IPv6 address	-	MAAS IPv6 subnet to register instances in (when using `network` property on NIC)
`user.*`	string	-	-	User-provided free-form key/value pairs
