Host Operating System Support Matrix

This page describes which host operating systems are supported for each Private Cloud Director release, along with deprecation timelines and end-of-support dates.

PCD Release	Ubuntu 22.04	Ubuntu 24.04	Platform9 OS powered by Rocky Linux from CIQ (RLC) 10.2
January 2026	Supported	Supported	--
April 2026	Supported	Supported	--
August 2026	Deprecated	Supported	Supported
October 2026	Deprecated	Supported	Supported
January 2027	Deprecated	Supported	Supported
April 2027	End of support	Supported	Supported

Legend:

• Supported = fully tested and maintained
• Deprecated = still functional, but no longer recommended for new deployments; plan to migrate
• End of support = no longer tested, patched, or supported

Ubuntu Support

Ubuntu host operating systems follow a bring-your-own-OS model. You provide, install, and maintain Ubuntu yourself, and Platform9 supports Private Cloud Director on the Ubuntu versions marked Supported in the table above. Platform9 does not package, harden, or manage the Ubuntu operating system, and there is no Platform9-delivered Ubuntu image equivalent to Platform9 OS.

Rocky Linux Support

Private Cloud Director is supported only on Platform9 OS powered by Rocky Linux from CIQ (RLC) 10.2 and installed through the Platform9 OS ISO. Platform9 OS is a controlled, hardened configuration: it is hardened to the CIS Level 1 benchmark and is configured to pull packages and updates only from the Platform9 validated package repository. Platform9 builds, tests, patches, and supports this operating system together with PCD as a single integrated stack.

Community Rocky Linux is not a supported PCD host operating system. This applies regardless of the version number: a host running community Rocky Linux 10.2 is still unsupported, because it does not carry the Platform9 OS hardening and does not use the Platform9 validated package repository, so it is not the configuration PCD is built and tested against. Private Cloud Director installed on a customer-provided Rocky Linux host is an unsupported configuration.

Important dates

August 2026: Ubuntu 22.04 is deprecated. New cluster deployments should use Ubuntu 24.04 or Platform9 OS powered by Rocky Linux 10.2.

January 2027: Last PCD release that includes Ubuntu 22.04 support.

April 2027: Ubuntu 22.04 reaches end of support. Hosts running Ubuntu 22.04 must be migrated before upgrading to this release.

Migration between host operating systems

Workload migration support depends on whether the source and destination hosts run the same host operating system.

Migration type	Between Ubuntu and Platform9 OS hosts	Between Platform9 OS hosts
Live migration	Not supported	Supported
Cold migration	Supported	Supported
