Hardware Virtualization Extension
This document describes the steps to validate that your server hardware that you plan to use with Private Cloud Director has virtualization hardware extensions enabled.
Private Cloud Director uses KVM hypervisor underneath which relies on hardware virtualization extensions (Intel VT-x or AMD-V) for full virtualization.
Specifically, Private Cloud Director requires that your servers run with:
- an Intel processor with Intel VT-x and Intel 64 virtualization extensions enabled, or
- an AMD processor with AMD-V and AMD64 virtualization extensions enabled
Follow the steps below to check if your server hardware comes with hardware virtualization extensions and if they are enabled.
Run the following command to validate that CPU virtualization extensions are available on your server:
$ grep -E 'svm|vmx' /proc/cpuinfoIf the above command returns any output, that means your server hardware contains the hardware virtualization extensions.
In the output, look for a vmx entry, indicating an Intel processor with the Intel VT-x extension enabled, or an svm entry, indicating an AMD processor with the AMD-V extensions enabled.
In some cases, manufacturers may have disabled the virtualization extensions in the server BIOS settings. If the output of the above command is empty, or if full virtualization does not work, find your server and processor specific instructions on enabling the extensions in your server BIOS configuration.
