(Virtualization technology has been successfully used in IBMPower servers based on POWER architecture. How to use virtualization technology in IBMSystemx series servers based on x86 manager? The latest IntelVT (Virtualization Technology) and AMDSVM (Secure Virtual Machine, SecureVirtualMachine, also called AMD-V) support virtualization technology from hardware. KVM utilizes the characteristics of x86 hardware virtualization to optimize the performance of virtual machines. This paper introduces in detail how to install and configure multiple virtual machines using SLES11 and KVM virtualization technology on IBM System x3500, and optimize the performance of virtual machines.)
