## Synopsis

- This module can be used to manage the VMKernel adapters / VMKernel network interfaces of an ESXi host.

- The module assumes that the host is already configured with the Port Group in case of a vSphere Standard Switch (vSS).

- The module assumes that the host is already configured with the Distributed Port Group in case of a vSphere Distributed Switch (vDS).

- The module automatically migrates the VMKernel adapter from vSS to vDS or vice versa if present.

## Requirements

The below requirements are needed on the host that executes this module.

- python >= 2.6

- PyVmomi

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
device string added in 2.8 |  | Search VMkernel adapter by device name. The parameter is required only in case of `type` is set to `dhcp`.
dvswitch_name string added in 2.8 |  | The name of the vSphere Distributed Switch (vDS) where to add the VMKernel interface. Required parameter only if `state` is set to `present`. Optional parameter from version 2.8 and onwards. aliases: dvswitch
enable_ft boolean | Choices: no yes | Enable Fault Tolerance traffic on the VMKernel adapter. This option is only allowed if the default TCP/IP stack is used.
enable_mgmt boolean | Choices: no yes | Enable Management traffic on the VMKernel adapter. This option is only allowed if the default TCP/IP stack is used.
enable_provisioning boolean added in 2.8 | Choices: no yes | Enable Provisioning traffic on the VMKernel adapter. This option is only allowed if the default TCP/IP stack is used.
enable_replication boolean added in 2.8 | Choices: no yes | Enable vSphere Replication traffic on the VMKernel adapter. This option is only allowed if the default TCP/IP stack is used.
enable_replication_nfc boolean added in 2.8 | Choices: no yes | Enable vSphere Replication NFC traffic on the VMKernel adapter. This option is only allowed if the default TCP/IP stack is used.
enable_vmotion boolean | Choices: no yes | Enable vMotion traffic on the VMKernel adapter. This option is only allowed if the default TCP/IP stack is used. You cannot enable vMotion on an additional adapter if you already have an adapter with the vMotion TCP/IP stack configured.
enable_vsan boolean | Choices: no yes | Enable VSAN traffic on the VMKernel adapter. This option is only allowed if the default TCP/IP stack is used.
esxi_hostname string / required added in 2.5 |  | Name of ESXi host to which VMKernel is to be managed. From version 2.5 onwards, this parameter is required.
hostname string |  | The hostname or IP address of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_HOST` will be used instead. Environment variable support added in Ansible 2.6.
ip_address string |  | The IP Address for the VMKernel interface. Use `network` parameter with `ip_address` instead. Deprecated option, will be removed in version 2.9.
mtu integer | Default: 1500 | The MTU for the VMKernel interface. The default value of 1500 is valid from version 2.5 and onwards.
network dictionary added in 2.5 | Default: {"tcpip_stack": "default", "type": "static"} | A dictionary of network details. The following parameter is required: - `type` (string): Type of IP assignment (either `dhcp` or `static`). The following parameters are required in case of `type` is set to `static`: - `ip_address` (string): Static IP address (implies `type: static`). - `subnet_mask` (string): Static netmask required for `ip_address`. The following parameter is optional in case of `type` is set to `static`: - `default_gateway` (string): Default gateway (Override default gateway for this adapter). The following parameter is optional: - `tcpip_stack` (string): The TCP/IP stack for the VMKernel interface. Can be default, provisioning, vmotion, or vxlan. (default: default)
password string |  | The password of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_PASSWORD` will be used instead. Environment variable support added in Ansible 2.6. aliases: pass, pwd
port integer added in 2.5 | Default: 443 | The port number of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_PORT` will be used instead. Environment variable support added in Ansible 2.6.
portgroup_name string / required |  | The name of the port group for the VMKernel interface. aliases: portgroup
proxy_host string added in 2.9 |  | Address of a proxy that will receive all HTTPS requests and relay them. The format is a hostname or a IP. If the value is not specified in the task, the value of environment variable `VMWARE_PROXY_HOST` will be used instead. This feature depends on a version of pyvmomi greater than v6.7.1.2018.12
proxy_port integer added in 2.9 |  | Port of the HTTP proxy that will receive all HTTPS requests and relay them. If the value is not specified in the task, the value of environment variable `VMWARE_PROXY_PORT` will be used instead.
state string added in 2.5 | Choices: present ← absent | If set to `present`, the VMKernel adapter will be created with the given specifications. If set to `absent`, the VMKernel adapter will be removed. If set to `present` and VMKernel adapter exists, the configurations will be updated.
subnet_mask string |  | The Subnet Mask for the VMKernel interface. Use `network` parameter with `subnet_mask` instead. Deprecated option, will be removed in version 2.9.
username string |  | The username of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_USER` will be used instead. Environment variable support added in Ansible 2.6. aliases: admin, user
validate_certs boolean | Choices: no yes ← | Allows connection when SSL certificates are not valid. Set to `false` when certificates are not trusted. If the value is not specified in the task, the value of environment variable `VMWARE_VALIDATE_CERTS` will be used instead. Environment variable support added in Ansible 2.6. If set to `yes`, please make sure Python >= 2.7.9 is installed on the given machine.
vswitch_name string |  | The name of the vSwitch where to add the VMKernel interface. Required parameter only if `state` is set to `present`. Optional parameter from version 2.5 and onwards. aliases: vswitch

## Notes

Note

- The option `device` need to be used with DHCP because otherwise it’s not possible to check if a VMkernel device is already present

- You can only change from DHCP to static, and vSS to vDS, or vice versa, in one step, without creating a new device, with `device` specified.

- You can only create the VMKernel adapter on a vDS if authenticated to vCenter and not if authenticated to ESXi.

- Tested on vSphere 5.5 and 6.5
