Xen 4.20 Hypervisor Brings AMD Zen 5 Support
Quoting: Xen 4.20 Hypervisor Brings AMD Zen 5 Support —
Seven months after its previous 4.19 release, the Xen Project, an open-source type-1 hypervisor using a microkernel design, has just released its new version, 4.20, which expands hardware support for both x86 and Arm platforms while introducing several compelling new capabilities.
On the Arm side, support has been added for LLC (Last Level Cache) coloring, which should help fine-tune performance by allowing more granular control over cache allocation. Furthermore, users can now experiment with the early-stage Armv8-R support, complementing the growing list of architectures that Xen accommodates.
