CENTOS6.4上KVM，vnc搭建
环境：host: CENTOS6.4 主要步骤：安装软件包配置桥接网络配置VNC 1.安装软件包 yum installqemu-kvm yum install libvirt yuminstall libvirt-python 其实CENTOS6.4上已经安装了这三个软件包，不用再装了。rpm -qa | grep qumu-kvmrpm -qa | grep libvirtrpm -qa | grep libvirt-python 运行 lsmod | grepkvm 和 stat /dev/kvm 确认kvm是否安装成功。 kvm服务名：libvirtd，重启一下服务确认是否能正常启动。service libvirtdrestart 报错处理yum -yupgrade device-mapper-libs2.配置网络使用桥接方式1). 创建配置文件# cp/etc/sysconfig/network-scripts/ifcfg-eth0/etc/sysconfig/network-scripts/ifcfg-br0# vim/etc/sysconfig/network-scripts/ifcfg-br0DEVICE=br0TYPE=BridgeONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=noneIPADDR=100.0.7.117NETMASK=255.255.255.0GATEWAY=100.0.6.1DNS1=202.106.196.115 # vim/etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth0HWADDR=90:2b:34:b0:c2:1aTYPE=EthernetUUID=48a302ce-3807-4409-a0ce-9e398c9e32cbONBOOT=yesNM_CONTROLLED=noBOOTPROTO=none#IPADDR=100.0.7.117#NETMASK=255.255.255.0#GATEWAY=100.0.6.1#DNS1=202.106.196.115IPV6INIT=noUSERCTL=noBRIDGE=br0 2).关闭NetworkManager,重启网络# chkconfig NetworkManager off# chkconfig --levels 35 network on# /etc/init.d/NetworkManager stop# /etc/init.d/network restart虚拟机上网echo1 > /proc/sys/net/ipv4/ip_forward 3).查看桥接网络# brctl showbridge namebridge idSTPenabledinterfacesbr08000.902b34b0c21anoeth0virbr08000.525400c8848eyesvirbr0-nic 3.配置vnc# yum install tigervnc-server编辑/etc/sysconfig/vncservers 增加一行:VNCSERVERS="1:root"设置password# vncpasswd 启动服务# /etc/init.d/vncserver restart 查看服务端口# netstat -nulpt | grep vnctcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 394/Xvnc tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN 394/Xvnc tcp 0 0 0.0.0.0:5910 0.0.0.0:* LISTEN 23040/Xvnc tcp 0 0 0.0.0.0:6010 0.0.0.0:* LISTEN 23040/Xvnc tcp 0 0 :::6001 :::* LISTEN 394/Xvnc tcp 0 0 :::6010 :::* LISTEN 23040/Xvnc(配置过程中可能多添加了几个，所以监听端口号比较多)到找这里kvm安装完成了！学习了
