KVM-虚拟化环境安装

宿主机系统:CentOS 6.8

下面是安装过程记录:

1.操作系统环境安装

(1)修改内核模式为兼容内核启动

[root@ops ~]# uname -a
Linux openstack 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

[root@ops ~]#vim /boot/grub/grub.conf

......

default=1     #由默认的0改为1,内核兼容模式

(2)关闭selinux,重启后生效

[root@ops ~]#vim /etc/sysconfig/selinux
......
SELINUX=disabled

[root@ops ~]#setenforce 0
setenforce: SELinux is disabled
[root@ops ~]#getenforce
Disabled

(3)关闭防火墙
[root@ops ~]#chkconfig ip6tables off
[root@ops ~]#chkconfig iptables off

(4)重启
[root@ops ~]#reboot

2.虚拟化环境配置

(1)查看是否支持虚拟机
说明1:半虚拟化是不能运行与安装KVM虚拟机的。
[root@ops ~]#egrep '(vmx|svm)' --color=always /proc/cpuinfo          

(2)配置yum环境,确认yum源是好使的。(这一步骤省略,可以用默认yum源,也可以换用163或阿里的yum源,只要能正常使用就行)

(3)安装kvm软件包
[root@ops ~]#yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v

补充安装kvm虚拟化一些管理工具包
[root@ops ~]#yum -y install libguestfs-tools

*******************************如果是centos7,操作如下****************************************
yum install qemu-kvm libvirt libvirt-python libguestfs-tools virt-install
systemctl enable libvirtd && systemctl start libvirtd
************************************************************************************

3.查看虚拟化环境

(1)查看虚拟机环境
[root@ops ~]# /etc/init.d/libvirtd restart
Stopping libvirtd daemon: [ OK ]
Starting libvirtd daemon: [ OK ]

----------------------------------------------------------------------------------------
启动的时候报错如下:
Starting libvirtd daemon: libvirtd: relocation error: libvirtd: symbol dm_task_get_info_with_deferred_remove, version Base not defined in file libdevmapper.so.1.02 with link time reference [FAILED]

解决办法:
yum upgrade device-mapper-libs
----------------------------------------------------------------------------------------

[root@ops ~]# virsh -c qemu:///system list
Id Name State
----------------------------------------------------

(2)查看kvm模块支持
[root@ops ~]# lsmod |grep kvm
kvm_intel 54285 0
kvm 333172 1 kvm_intel

(3)查看虚拟工具版本
[root@ops ~]# virsh --version
0.10.2
[root@ops ~]# virt-install --version
0.600.0
[root@ops ~]# ln -s /usr/libexec/qemu-kvm /usr/bin/qemu-kvm

4.手动配置虚拟网桥

(1)关闭networkmanager服务
[root@ops ~]# chkconfig NetWorkManager off
[root@ops ~]# /etc/init.d/NetWorkManager stop

(2)创建br0网桥
[root@ops ~]#cd /etc/sysconfig/network-scripts/
[root@ops ~]#cp ifcfg-em2 ifcfg-br0                     #em2是本机内网网卡

[root@ops ~]# cat ifcfg-em2
DEVICE=em2
HWADDR=44:A8:42:21:A6:01
TYPE=Ethernet
BRIDGE=br0                                           #将em2添加到网桥br0内
UUID=6dbfbd49-b6b9-4c51-b2d2-b3ecbead82e9
ONBOOT=yes
IPADDR=192.168.1.17
GATEWAY=192.168.1.1
NM_CONTROLLED=no                           #一定设置为no!让em2不受networkmanager的控制
BOOTPROTO=static

[root@ops ~]# cat ifcfg-br0
DEVICE=br0
HWADDR=44:A8:42:21:A6:01
TYPE=Bridge
UUID=6dbfbd49-b6b9-4c51-b2d2-b3ecbead82e9
ONBOOT=yes
IPADDR=192.168.1.17
GATEWAY=192.168.1.1
NM_CONTROLLED=no
BOOTPROTO=static

(3)关闭了networkmanager服务之后,才能通过重启网卡服务管理网络。
[root@ops ~]# /etc/init.d/network restart

(4)查看网桥br0信息
[root@ops ~]# ifconfig

(5)查看网桥
[root@ops ~]# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.44a84221a601 no em2
virbr0 8000.5254005f95b7 yes virbr0-nic

到此kvm虚拟化环境安装完毕。
