Configure kernel modules

Configure kernel modules

The OpenStack Nova and Neutron services may require additional kernel modules to be loaded for normal operation. This section instructs you on how to enable the required kernel modules.

To enable KVM

A kernel-based Virtual Machine (KVM) is a virtualization module in the Linux kernel that enables the kernel to function as a hypervisor. The KVM-based virtualization is recommended on compute hosts to provide high performance VMs. See OpenStack Train official documentation: Enable KVM for details.


Some systems require that you enable the VT support in the system BIOS. To enable the VT support, refer to the BIOS guides of the manufacturer of your server motherboard.
