Getting started with Linux: KVM for Virtual Machine experience
In the previous article, I demonstrated the use, effect and performance of the Virtual Machine Software QEMU, and analyzed the different virtual machine pursuits of different users. However, whether it is a desktop or enterprise-level user, the pursuit of
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 of the Xen
KVM Virtual Machine IntroductionIntroduction to a KVM Virtual Machine (kernel-based Virtual Machine) is an open-source system virtualization module. It has been integrated into major Linux releases since Linux 2.6.20. It uses the Linux Scheduler for management, so compared w
Linux has both good flexibility and excellent virtualization. But recently, with the emergence of kernel Virtual Machine KVM), the prospect of Linux Virtualization has changed. KVM is the first virtualization solution that forms part of mainstream Linux kernel V2.6.20. KVM supports Virtualization of Linux customers' op
ObjectiveThe purpose of this article is to solve the problem of poor performance of Windows virtual machines when using Cloudstack (Cloudplatform), based on the KVM virtualization platform.This performance, mainly refers to disk IO and network card performance.Related documentsSince the CS document only emphasizes the concept of PV, different hardware interface types are distinguished according to PV mode.

I. Prerequisites for installation:
1. Make sure the motherboard supports intel-VT or AMD-V
2. rhel 6.4 in VMware has been installed and the virtual machine has been set to support virtualization. The settings are as f
How to Use the command line tool in Linux to manage the KVM Virtual Environment
In the fourth part of our KVM series, we will discuss how to manage the KVM environment on the command line interface. We use the 'virt-install' and virsh command line tools to create and configure virt
This paper mainly introduces the static and dynamic migration of the KVM virtual machine, which is as follows:
One, KVM virtual machine static migration
1. The static migration is the virtual machine in the Shutdown state, copy virtual

Recently in the study of KVM, the process is not too fast, recently organized a KVM virtual machine technology Learning notes, now share to everyone, but also for everyone to make a reference. A friend in need can come to know.

KVM supports multiple storage options, including virtual disk files, file system-based storage, and device-based storage.
Virtual Disk File
To implement kernel-based Virtual Machine (KVM) storage management, you can use LVM (logical volume manager) and create a storage pool.

Introduction to Nesting Virtualization
Nested virtualization (nested virtualization, recursive virtualization) is the process of running a hypervisor in a virtualized client, which is then virtualized to run a client. Nested virtualization includes not only the same hypervisor nesting (for example, KVM on KVM, Xen in Xen, VMware on VMware, and so on), but also the different hypervisor nesting (such as VMwa

virtual machine directly to the physical hardware, thereby improving the performance of the operating system running in the virtual machine. Such as:KVM is a typical representation of this acceleration pattern. In the community, KVM and Xen are often compared, but they are totally different. As can be seen, the use of kernel modules to accelerate this mode, the
