Kernel-Based Virtual Machine Ported To ARM64 58

hypnosec writes "Linux KVM has been ported to ARM64 just ahead of the release of the architecture, it has been revealed. Just last year ARM KVM virtualization support for Cortex-A15 32bit ARM processor was published. Marc Zyngier of ARM released a set of 29 patches that contained the implementation of KVM for ARM that depends on the pre-arm64 rework as well as tiny perf patch published earlier. Some of the newly released port are support for 4k and 64k pages and 32-bit as well as 64-bit guests."

    Xen is indeed the platform on which Amazon ec2 is based, but I would say that decision might be made differently today if given the chance. First off, at the time when it was being created, Xen was the only real option. KVM simply didn't exist until after ec2's launch in 2006, and the only real alternative was VMware. Second, ec2 initially used Paravirtualization exclusively, meaning hardware-assited virtualization functionality wasn't required or used, and performance was extremely good, but compatibility was limited to Xen-aware Linux systems. Fast forward to today and KVM-enabled kernels are performance-comparable to Paravirtualized Xen instances, good Windows drivers exist for KVM virtualized hardware, and maybe most importantly, KVM is part of the kernel of all major Linux distributions.
