Synopsis

  • This module can be used to configure, enable or disable SR-IOV functions on ESXi host.

  • Module does not reboot the host after changes, but puts it in output “rebootRequired” state.

  • User can specify an ESXi hostname or Cluster name. In case of cluster name, all ESXi hosts are updated.

Requirements

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

  • python >= 2.7

  • PyVmomi

Examples

- name: enable SR-IOV on vmnic0 with 8 functions
  community.vmware.vmware_host_sriov:
    hostname: "{{ vcenter_hostname }}"
    username: "{{ vcenter_username }}"
    password: "{{ vcenter_password }}"
    esxi_hostname: "{{ esxi1 }}"
    vmnic: vmnic0
    sriov_on: true
    num_virt_func: 8

- name: enable SR-IOV on already enabled interface vmnic0
  community.vmware.vmware_host_sriov:
    hostname: "{{ vcenter_hostname }}"
    username: "{{ vcenter_username }}"
    password: "{{ vcenter_password }}"
    esxi_hostname: "{{ esxi1 }}"
    vmnic: vmnic0
    sriov_on: true
    num_virt_func: 8

- name: enable SR-IOV on vmnic0 with big number of functions
  community.vmware.vmware_host_sriov:
    hostname: "{{ vcenter_hostname }}"
    username: "{{ vcenter_username }}"
    password: "{{ vcenter_password }}"
    esxi_hostname: "{{ esxi1 }}"
    vmnic: vmnic0
    sriov_on: true
    num_virt_func: 100
  ignore_errors: true

- name: disable SR-IOV on vmnic0
  community.vmware.vmware_host_sriov:
    hostname: "{{ vcenter_hostname }}"
    username: "{{ vcenter_username }}"
    password: "{{ vcenter_password }}"
    esxi_hostname: "{{ esxi1 }}"
    vmnic: vmnic0
    sriov_on: false
    num_virt_func: 0

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key Returned Description
host_sriov_diff
dictionary
always
contains info about SR-IOV status on vmnic before, after and requested changes
sometimes vCenter slowly update info, as result "after" contains same info as "before" need to run again in check_mode or reboot host, as ESXi requested

Sample:
{'changed': True, 'diff': {'after': {'host_test': {'maxVirtualFunctionSupported': 63, 'numVirtualFunction': 0, 'numVirtualFunctionRequested': 8, 'rebootRequired': True, 'sriovActive': False, 'sriovCapable': True, 'sriovEnabled': True}}, 'before': {'host_test': {'maxVirtualFunctionSupported': 63, 'numVirtualFunction': 0, 'numVirtualFunctionRequested': 0, 'rebootRequired': False, 'sriovActive': False, 'sriovCapable': True, 'sriovEnabled': False}}, 'changes': {'host_test': {'numVirtualFunction': 8, 'rebootRequired': True, 'sriovEnabled': True}}}}
