In the conventional x86 or x86-64 bit system, virtualization is commonly achieved with KVM or Xen which is widely adapted in many experimental or commercial server system. At now, It is common sense that high and mid volume servers are virtualized with Xen, mid and small volume servers are virtualized with KVM. Recently, the microserver system concept was introduced, which contains low power and multicore ARM64bit sever SoCs. We present the KVM-QEMU virtualization technique and process in a real ARM64bit microserver system with ubuntu 14.04 ARM64 bit edition root file system.
