It’s been a little over five months since the release of the Xen 4.7 series, and it looks like the development team behind this highly customizable, extensible and flexible type-1 or baremetal hypervisor did not stop improving the software and adding new features to it. Xen 4.8 is the latest stable and most advanced version, which focuses on advanced embedded use cases and enhances support of ARMv8-A based servers. Prominent new features of the Xen 4.8 hypervisor include initial support for ARM server Live Patching, which, as expected, lets users apply security fixes without rebooting, support for the GICv2m interrupt controller with MSI capabilities, as well as mmio-sram and IO memory regions that contain special caching requirements. Production-ready support for the scalable Credit2 scheduler is also present in Xen 4.8.
