New version of SUSE Linux Enterprise 15 SP1 released


After a year of development, SUSE presented the launch of thea new version of your SUSE Linux Enterprise 15 SP1 distribution. SUSE 15 SP1 packages have already been used as the basis for the openSUSE Leap 15.1 distribution compatible with the community.

Products such as SUSE Linux Enterprise Server, SUSE Linux Enterprise Desktop, SUSE Manager, and SUSE Linux Enterprise High Performance Computing are also based on the SUSE Linux Enterprise platform.

Major Changes in SUSE Linux Enterprise 15 SP1

In this new version the migration of openSUSE server installations to the SUSE Linux Enterprise distribution was simplified and accelerated, allowing system integrators to first build and test a working openSUSE-based solution and then switch to a commercial version with full support, SLA, certification, long-term updates, and advanced tools for mass deployment.

SUSE Linux Enterprise users have received the SUSE Package Hub repository, which provides access to additional applications and new versions supported by the openSUSE community.


Editing SUSE Linux Enterprise Server for ARM64 architecture doubled the number of supported SoCs and expanded hardware support.

For example, for 64-bit Raspberry Pi cards, support for audio and video transmission via HDMI has been added, Chrony time synchronization has been included and a separate ISO image has been prepared for installation.

As well Full support provided for the AMD Secure Encrypted Virtualization protection mechanism (AMD SEV), which enables transparent memory encryption of virtual machines, where only the current guest system has access to the decrypted data, and the rest of the virtual machines and the hypervisor obtain encrypted data when accessing this memory.

Support for encrypting individual memory pages using SME technology was added (Secure Memory Encryption) introduced in AMD processors.

SME allows you to mark memory pages as encrypted, after which these pages will be automatically encrypted when written to DRAM and decrypted when read from DRAM. SMEs are compatible with AMD processors from the 17h family.

Work was done to optimize performance and reduce lag when used in systems with Intel Optane DC permanent memory and XNUMXnd generation Intel Xeon Scalable processors.

Additionally, dynamic mapping is disabled for the root Xen environment. For dom0, now the default is 10% RAM size + 1GB (for example, if there is 32GB RAM, 4.2GB will be allocated to Dom0)


On the side of the desk, Gnome was improved to work on high pixel density (HiDPI) systems. If the display DPI exceeds 144, then Gnome will now automatically apply 2: 1 scaling (the value can be changed in the Gnome Control Center).

Gnome Initial Configuration Wizard has been added (gnome-initial-setup) that starts when you log in for the first time after installation, which provides options for customizing keyboard layout and input methods (other GNOME initial setup options are disabled).

While installation was simplified using the "Modular +" modular architecture, where specific features such as server products, desktop, cloud systems, developer tools, and container tools are designed as modules, updates, and patches for which they are released as part of a separate appliance.

The support cycle and can be formed more quickly, without waiting for the upgrade of the entire monolithic distribution. Products such as SUSE Manager, SUSE Linux Enterprise Real Time, and SUSE Linux Enterprise Point of Service are now available for installation in the form of modules.

Btrfs adds support for free block cache (Free Space Tree or Free Space Cache v2), storing the swap partition in a file and changing the UUID metadata.

Python 2 is excluded from the base release and only Python 3 remains (Python 2 is now available as a separately installable module.)
