This is the 2nd chapter in the OpenStack implementation experience sharing series.OpenStack deploys instance through Glance mirroring, the previous section introduces the Linux image authoring method, Windows mirroring is very different from Linux, and today we take windows2008 as an example to discuss it in detail.The image production steps are as follows:1. Create and run the windows2008 KVM virtual machi

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

the Guestos is instantiated. The physical memory mapped to Guestos is actually mapped to the virtual memory of the corresponding process in the Guestos in VMM.There are two translation methods that support the guest address to the host (VMM) address: A set of Shadow page tables (Shadow page table) that are maintained by applying Linuxos can also use VMM (host kernel) when accessing unmapped memory locations To support the memory conversion process. so in general, the/DEV/

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,

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
