Brief introductionKVM is a shorthand for kernel Virtual machine, and currently Red Hat only supports running KVM on 64-bit RHEL5.4 and above, while hardware needs to support VT technology. KVM, formerly known as Qemu,2008, was acquired by Red Hat and acquired a hypervisor technology, but Red Hat's KVM is considered to be the mainstream of future Linux hypervisor,

What is KVM? A KVM is a virtual machine based on a Linux core (kernel-based virtual Machine). A new "Virtual machine" Implementation program developed by Israel's Qumranet organization in October 2006. The Linux 2.6.20 kernel, released in February 2007, contains KVM for the first time. Adding KVM to the Linux kernel i

The relationship between QEMU and KVM: Virtualization, which is now described, is generally referred to as virtualization technology based on CPU hardware support. KVM relies on this technology as well as Hyper-V and Xen. Without the support of CPU hardware virtualization, KVM is not working. To be exact, KVM is a mo

Environment: HOST: centos 5.6 x86_64 + KVM Virtual Machine: centos 5.6 x86_64, Windows 2003 Server Problem: On a physical machine, you can use a domain name to access a website. On a virtual machine, you cannot use a domain name to access the website, but you can access the website through an IP address. After the firewall (iptables) of the physical machine is disabled, the virtual machine

Quick understanding of Snapshots Please refer to virtual machine snapshot analysisObjective:Through a basic image (backing files, the basic image), inside the various virtual machines need to set up the environment, and then based on this image to establish an incremental image, each incremental image corresponding to a virtual machine, the virtual machine on the mirror all the changes are recorded in the incremental image inside, The underlying image is always intact.Features: Save disk space a

There are a lot of instructions on KVM, but it is basically a command line. It is not intuitive for new users, and it is not mentioned about virtio driver installation. So I sent another article. The performance of the virtual hard disk and virtual network using the virtio interface is not comparable to that of the default ide interface. From Installing a virtual machine to running a virtual system, you only need to use the command line three time

Prior to the VirtualBox nested installation of KVM virtualization, the use of VNC viewer to install the child, the speed is OK, but the installation system after the start of the machine is very slow. The login interface takes approximately twenty or thirty minutes from boot to appearance. The adjustment has been adjusted, but also to upgrade the VirtualBox to the latest 5.0, or not. It was later found that if you use the default virtual disk format r

By default, if you do not specify any network mode, KVM will silently choose NAT mode for us, in addition to NAT there is bridge and VLAN mode.User Networking (NAT mode)With this mode, no additional configuration is required for the host. Under normal circumstances, the virtual machine can access the host's physical network directly, and the host cannot access the virtual machine.The benefit is simple, no configuration, and if the host can surf the In

It takes a lot of effort to clone a KVM Virtual Machine and recreate it each time. Therefore, cloning is a good idea. There is no direct clone menu in Hyper-V, and export and import are required. You also need to modify the name file and the like. On the contrary, it is very simple to operate in KVM. Assume that you have a vm1 Vm, and now you want to clone the vm2 VM. Follow these steps: 1. Stop vm1 [plain]

) Use a complete physical disk as storage. A partition is created for each volume that is added to the pool.

Reference Migration: Migrations that involve the overall system and migration of a workload can be categorized into the following categories according to the characteristics of the migration:Static migration (cold migration): Refers to the migration process for a period of time, the client's service is not available, it can also be divided into two, one is to completely shut down the client, the hard disk image copied to another host and then started up, this does not save the client's workload
