Note: Ensure you review and verify that you meet the increased memory requirements. For more information, see Hardware requirements.
IBM® Cloud Private supports the following 64-bit operating systems: Linux®; and Linux® on Power® (ppc64le).
| Platform | Operating system |
|---|---|
| Linux® x86_64 | Red Hat Enterprise Linux (RHEL) 7.4, 7.5, 7.6, and 7.7 |
| Ubuntu 18.04 LTS and 16.04 LTS | |
| SUSE Linux Enterprise Server (SLES) 12 SP4 | |
| Linux® on Power® (ppc64le) POWER8® or later |
Red Hat Enterprise Linux 7.4, 7.5*, 7.5-Alt, 7.6, 7.6-Alt, and 7.7 |
| Ubuntu 18.04 LTS (KVM and Bare Metal only) and Ubuntu 16.04 LTS | |
| SUSE Linux Enterprise Server 12 SP4 | |
| Linux® on IBM® Z and LinuxONE | Red Hat Enterprise Linux 7.3, 7.4, 7.5, 7.6, and 7.7 |
| Ubuntu 18.04 LTS and 16.04 LTS | |
| SUSE Linux Enterprise Server 12 SP4 |
-
RHEL 7.5 users on POWER9™ must be sure to install the latest
kernel-altkernel that is provided by RHEL. -
If you use RHEL 7.7 or 7.8 on Linux® on IBM® Z and LinuxONE, you must install the
libseccomplibrary version 2.3.3 or later before you install IBM Cloud Private. To install this library version, run the following commands:wget https://oplab9.parqtec.unicamp.br/pub/s390x/libseccomp/libseccomp-2.3.3-3.el7.s390x.rpm yum install libseccomp-2.3.3-3.el7.s390x.rpm -yRun the following command to verify that the
libseccomplibrary version is2.3.3:rpm -qi libseccomp | grep Version -
RHEL 7.7 users on Linux® on IBM® Z and LinuxONE, you must install the
libseccomplibrary version 2.3.3 or later before you install IBM Cloud Private.
Important: VA does not support SLES. You can enable the support for SLES by applying the Fix Central patch 
.
Note: Check the documentation for your operating system to ensure that you are using a supported kernel level.
IBM Cloud Private components are distributed as a set of Docker images that incorporate their own operating system dependencies. It is recommended that you use one of the certified operating systems that are listed in the preceding table. However, IBM Cloud Private can run on any Linux operating system that supports Docker 1.12 and later.

Notes:
- IBM Cloud Private supports new versions of supported operating systems, Kubernetes, Docker, and other dependent infrastructure after new releases happen and when they are fully tested by the IBM Cloud Private team.
- Support for the Cloud Manager Appliance (CMA) on z/VM v7.1 is a transitional offer until a strategic long-term solution to replace the CMA becomes available.
- For the Cloud Manager Appliance on z/VM v7.1, support is limited to an earlier version of OpenStack and earlier versions of Linux Distributions for deployment, without plans to upgrade. The supported OpenStack version is "Newton". The
supported Linux® distributions for deployment are:
- RHEL 6.2, 6.3, 6.4, 6.5, 6.6, and 6.7
- RHEL 7.0, 7.1 and 7.2
- SLES 11.2, 11.3, and 11.4
- SLES 12 and SLES 12.1
- Ubuntu 16.04
- The Cloud Manager Appliance is available for z/VM v7.1 for the specific use case with IBM Cloud Private only.
- IBM account teams can request the Cloud Manager Appliance for z/VM v7.1 by contacting the responsible IBM Offering Manager.
