kvm虚拟化管理平台WebVirtMgr部署-完整记录
kvm虚拟化管理平台WebVirtMgr部署-完整记录
打算部署kvm虚拟机环境，下面是虚拟化部署前的一些准备工作：
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
Linuxopenstack2.6.32-431.el6.x86_64#1SMPFriNov2203:15:09UTC2013x86_64x86_64x86_64GNU/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~]#setenforce0
setenforce:SELinuxisdisabled
[root@ops~]#getenforce
Disabled
3）关闭防火墙
[root@ops~]#chkconfigip6tablesoff
[root@ops~]#chkconfigiptablesoff
4）重启
[root@ops~]#reboot
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-yinstallkvmpython-virtinstlibvirttunctlbridge-utilsvirt-managerqemu-kvm-toolsvirt-viewervirt-v2v
补充安装kvm虚拟化一些管理工具包
[root@ops~]#yum-yinstalllibguestfs-tools
---------------------------------------如果是centos7，操作如下---------------------------------------
yuminstallqemu-kvmlibvirtlibvirt-pythonlibguestfs-toolsvirt-installvirt-managerpython-virtinstlibvirt-clientvirt-viewer
systemctlenablelibvirtd&&systemctlstartlibvirtd
-----------------------------------------------------------------------------------------------------
查看虚拟化环境
1）查看虚拟机环境
[root@ops~]#/etc/init.d/libvirtdrestart
Stoppinglibvirtddaemon:[OK]
Startinglibvirtddaemon:[OK]
----------------------------------------------------------------------------------------------------------------------------------------------
启动的时候报错如下:
Startinglibvirtddaemon:libvirtd:relocationerror:libvirtd:symboldm_task_get_info_with_deferred_remove,versionBasenotdefinedinfilelibdevmapper.so.1.02withlinktimereference[FAILED]
解决办法：
yumupgradedevice-mapper-libs
----------------------------------------------------------------------------------------------------------------------------------------------
[root@ops~]#virsh-cqemu:///systemlist
IdNameState
----------------------------------------------------
2）查看kvm模块支持
[root@ops~]#lsmod|grepkvm
kvm_intel542850
kvm3331721kvm_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
手动配置虚拟网桥
1）关闭networkmanager服务
[root@ops~]#chkconfigNetWorkManageroff
[root@ops~]#/etc/init.d/NetWorkManagerstop
2）创建br0网桥
[root@ops~]#cd/etc/sysconfig/network-scripts/
[root@ops~]#cpifcfg-em2ifcfg-br0#em2是本机内网网卡
[root@ops~]#catifcfg-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~]#catifcfg-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/networkrestart
4）查看网桥br0信息
[root@ops~]#ifconfig
