Preface
The migration technology of virtual machines provides a simple method for server virtualization. Currently, popular virtualization products VMWare, xen, hyper-V, and KVM all provide their own migration tools. Among them, the Linux platform's open-source virtualization tool KVM has developed rapidly, and the migration features of
It turned out that using the VirtualBox hypervisor (VMM) to build virtual machines on the desktop was installed on different operating systems, and nowResearch KVM under Linux, can you convert an already established VirtualBox virtual client (guest) to a KVM virtual

XXX: the document states that either an Intel CPU with VT (vmx) or an SVM (secure virtual machine, also known as a AMD-V) must be availableAMD CPUInstall. I installed it on turion 64 X2. No problem.Whether AMD and Intel CPU support VT or SVM. For details, referKernelHas_svm () and cpu_has_kvm_support () of KVM ()Function.1. Ensure that the kernel version is 2.6.2
The key to migrating a VM from KVM to Xen is to replace the original kernel without Xen patches, and then select the appropriate grub (older versions of Xen do not support grub2 ). After completing the preceding two steps, make the image of the KVM virtual machine into an Xen image, and then use the configuration file

Introduction
The concept of Virtualization has long existed. Simply put, virtualization is the process of using certain programs and making them look similar to other programs. Applying this concept to a computer system allows different users to see different individual systems (for example, a computer can run both Linux and Microsoft? Windows ?). This is usually called full virtualization ).

Description:The lab environment used in this article is the VMware Workstation 12.5 Pro running on WINDOWS10, the host operating system is UBUNTU16 (machine name is kvm_test), Kvm+qemu+libvirt is installed on kvm_test. The client operating system running on Kvm_test is also Ubuntu16 (machine name is Test_ubuntu).The software required for this experiment is an iOS

); this thread calls the KVM kernel module to switch to the user mode and execute VM code. When a privileged command is run, it switches from the KVM kernel module. When required, the kernel module sends signals like Qemu threads to process most hardware simulation tasks.
