Linux 虚拟机之--KVM的安装和配置（一）
Linux 虚拟机之--KVM的安装和配置（一）
系统环境：
操作系统： RedHat EL6.4(x86_64)
一、前言
KVM，即Kernel-based Virtual Machine的简称，是一个开源的系统虚拟化模块，自Linux 2.6.20之后集成在Linux的各个主要发行版本中。它使用Linux自身的调度器进行管理，所以相对于Xen，其核心源码很少。KVM目前已成为学术界的主流VMM之一。KVM的虚拟化需要硬件支持（如Intel VT技术或者AMD V技术)。是基于硬件的完全虚拟化。而Xen早期则是基于软件模拟的Para-Virtualization，
新版本则是基于硬件支持的完全虚拟化。但Xen本身有自己的进程调度器，存储管理模块等，所以代码较为庞大。广为流传的商业系统虚拟化软件VMware ESX系列也是基于软件模拟的Para-Virtualization。
二、配置环境
软件包组：
virtualization 提供虚拟机的环境，主要包含qemu-kvm
virtualization-client 管理和安装虚拟机实例的客户端，主要有python-virtinst,virt-manager,virt-viewer
virtualization-platform 提供访问和控制虚拟客户端的接口，主要有libvirt，libvirt-client
virtualization-tools 管理离线虚拟机镜像的工具，主要有libguestfs
根据需求选择软件包，一般都安装前三个，也可以只安装个别主要的包。
为了减少不必要的麻烦，请关闭防火墙和SELinux
# cat /proc/cpuinfo |grep flags 需要全虚拟化支持为vmx(Inter)或svm（AMD）
三、安装KVM软件包
1、查看主机CPU信息
[root@rh64 ~]# cat /proc/cpuinfo|grep flag
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx rdtscp lm constant_tsc up rep_good xtopology nonstop_tsc unfair_spinlock pni pclmulqdq monitor ssse3 cx16 sse4_1 sse4_2 popcnt aes xsave avx hypervisor lahf_lm
2、查看系统内核版本
[root@rh64 ~]# uname -a
Linux rh64 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
3、通过系统安装盘安装kvm软件包
[root@rh64 ~]# mount /dev/sr0 /media
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@rh64 ~]# yum groupinstall "Virtualization" "Virtualization Client" "Virtualzation Platform"
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
