IBM Updates Linux Patches For Introducing ARM64 KVM Virtualization On s390 Written by Michael Larabel in Virtualization on 28 April 2026 at 12:54 PM EDT. 3 Comments At the start of April was the peculiar announcement of IBM collaborating with Arm on "dual architecture" hardware. The initial fruits of that collaboration at least are Linux kernel patches for enabling ARM64 virtualization acceleration on IBM Z servers. As we approach the end of the month, IBM has now posted a second iteration of those patches for enabling AArch64 software to run on IBM s390 via the Kernel-based Virtual Machine (KVM). IBM engineers today posted the second version of patches for ARM64 KVM on s390.
