community.vmware.vmware_host_kernel_manager module – Manage kernel module options on ESXi hosts

Note

This module is part of the community.vmware collection (version 5.7.2).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.vmware.

To use it in a playbook, specify: community.vmware.vmware_host_kernel_manager.

Synopsis

  • This module can be used to manage kernel module options on ESXi hosts.
  • All connected ESXi hosts in scope will be configured when specified.
  • If a host is not connected at time of configuration, it will be marked as such in the output.
  • Kernel module options may require a reboot to take effect which is not covered here.
  • You can use ansible.builtin.reboot or community.vmware.vmware_host_powerstate module to reboot all ESXi host systems.
