Installation

SUSE Virtualization can be installed using the ISO image, a bootable USB drive, and PXE boot. For more information, see the Installation section of the documentation.

The installation process includes a mandatory step for configuring the login password for the default rancher user account.

Upgrades

SUSE Virtualization only allows upgrades from supported versions. For more information about upgrade paths and procedures, see Upgrades.

The upgrade path was improved to ensure bonded network interfaces (such as mgmt-bo) retain their correct names after a reboot. The upgrade script now reads the unique permanent hardware address of each bonded NIC, preventing interface name shifting and potential network outages during cluster upgrades.

Security fixes

This release addresses security vulnerabilities in the following underlying components:

  • Operating system (SUSE Linux Micro): The BaseOS image was updated with the latest SUSE security patches for the Linux kernel, resolving several use-after-free vulnerabilities that could allow privilege escalation (#11209). For more information, see CVE-2026-53359, CVE-2026-43499, and CVE-2026-46242.

  • etcd (RKE2): RKE2 was updated to include a patched etcd version that resolves a denial-of-service vulnerability in the etcd TLS listener (GHSA-6vch-q96h-7gc3). This vulnerability could exhaust server memory and render the control plane or cluster unavailable.

Bug fixes

  • #11219 [backport v1.7] [BUG] Failed image cannot be deleted due to finalizer lock when a successful upload exists

  • #11103 [BUG] 1.7.2 still uses a broken whereabouts 0.9.2
