Networks

Update a hypervisor network

Since 7.1.0
PUT/compute/hypervisors/{hypervisorId}/networks/{networkId}

Change a network. Send only the fields to change; mtu: null clears the MTU and ipBlockGroupId: null unbinds the group. The primary network cannot be renamed.

Request

Authorization
Provide your bearer token in the Authorization header when making requests to protected resources.
Example: Authorization: Bearer ********************
Path Params#
hypervisorIdinteger#required

A valid hypervisor ID as shown in VirtFusion.

Example: 1
networkIdinteger#required

The hypervisor network ID, from the networks list.

Example: 2
Body Paramsapplication/json#

Any subset of the network's fields.

object
namestring#
Length: 3 to 30 characters
bridgestring#

Letters, digits, dot, dash and underscore only, and unique per hypervisor.

Length: 1 to 20 characters
Pattern: ^[A-Za-z0-9_.-]+$
typestring#

The network type. Each is named as on the hypervisor page, and bridge means something different for each:

TypeMeaning
simpleBridgeBridged. A Linux bridge on the hypervisor, such as br0. VLANs can be tagged on it.
lvBridgeOVSOpen vSwitch Bridged. An Open vSwitch bridge on the hypervisor controlled by Libvirt. VLANs can be tagged on it.
lvNetworkLibvirt Network. A Libvirt network defined on the hypervisor.
lvNetworkBridgeLibvirt Routed. A Libvirt network in routed mode.
lvNatv1NAT v1. A Libvirt NAT network; servers get private addresses and port forwards.
macVTapMacVTap. The physical interface the server attaches to directly, such as eth0.
