I. Structure and INTRODUCTION KVM (kernel-based Virtual Machine) It was developed by Quramnet, the company was acquired by Red Hat in 2008; Integrated into the kernel from the Linux 2.6.20, the kernel module makes Linux become a hypervisor layer; It relies on the CPU virtualization instruction set, performance, security, compatibility, stability performance is good, each virtualization operating system performance as a single system process, and Li

KVM: (kernel-based virtual machine) kernel-based VMS KVM is hypervisor integrated into the Linux kernel, a full-virtualization solution for Linux with X86 architecture and hardware-enabled virtualization technology (Intel VT or AMD-V). It is a very small module of Linux, using Linux to do a lot of things, such as task scheduling, memory management and hardware device interaction and so on. In the form of pr

One, what is KVMKVM includes many parts: first, it is a Linux kernel module (now included in the mainline) used to convert the processor into a new user (Guset) mode. User mode has its own set of ring states, but the command of privileged RING0 is caught in the code of the manager (hypervisor). Since this is a new processor execution model, the code does not require any changes. In addition to processor state transitions, this kernel module also handles a small subset of low-level simulations,

Execution Timer callback function3). Perform the lower half (BH) callback function. Why to adopt BH, the data says main avoids reentrant and call stack overflow.2. The thread that executes the client codeDiscuss only the

KVM in 2013 years or so in the company at that time as a production environment in use, the habit, in their normal test environment also no longer use VMware Workstation and exsi. Recently, however, we are learning about the Rhel 7 version of the RHCE course. Get a set of RHCE environment after decompression found to be VMDK format. After conversion through the Qemu-img tool, the KVM is imported and the env

Do you know how to add system calling APIs in KVM? Here we will describe different systems calling APIs and their implementations for different j2s devices, I believe this article will surely help you gain some benefits. How to add the system call API in KVM We all know that KVM does not support Native function calls. If you want to add some system-called APIs, y
