系统环境：CentOS 5.4_64一、安装所需包#for i in kvm kvm-qemu-img libvirt kmod-kvm python-virtinst bridge-utils tunctl virt-manager;do yum install $i -y;done
二、创建桥#!/bin/shif /sbin/ifconfig vSwitch0 down > /etc/null 2>&1 & then /usr/sbin/brctl delbr vSwitch0 > /etc/null 2>&1 & /sbin/ifconfig eth0 0.0.0.0 promisc up /usr/sbin/brctl addbr vSwitch0 /usr/sbin/brctl addif vSwitch0 eth0 /sbin/ifconfig vSwitch0 192.168.1.19 netmask 255.255.255.0 up /sbin/route add default gw 192.168.1.1 dev vSwitch0 else /sbin/ifconfig eth0 0.0.0.0 promisc up /usr/sbin/brctl addbr vSwitch0 /usr/sbin/brctl addif vSwitch0 eth0 /sbin/ifconfig vSwitch0 192.168.1.19 netmask 255.255.255.0 up /sbin/route add default gw 192.168.1.1 dev vSwitch0fi
把上述保存为一个脚本，然后添加到系统启动项
三、创建虚机1、定义xml文件<domain type=’kvm’> <name>tony-1</name> <uuid>0111310a-ff1a-bfb5-7cd8-5b2b22ad8de1</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> <type arch=’x86_64′ machine=’pc’>hvm</type> <boot dev=’cdrom’/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset=’localtime’/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> 注意此处的qemu-kvm路径 <disk type=’file’ device=’disk’> <source file=’/opt/datastore/tony-1.qcow2’/> <target dev=’hda’ bus=’ide’/> </disk> <disk type=’file’ device=’cdrom’> <target dev=’hdc’ bus=’ide’/> <source file=’/opt/datastore/deepin-9.iso’/> <readonly/> </disk> <interface type=’bridge’> <mac address=’00:e0:4c:f0:e0:11’/> <source bridge=’vSwitch0’/> <target dev=’vnet0’/> </interface> <input type=’tablet’ bus=’usb’/> <input type=’mouse’ bus=’ps2’/> <graphics type=’vnc’ port=’5900′ autoport=’yes’ listen=’0.0.0.0′ keymap=’en-us’/><!– <sound model=’es1370’/> –> 注释掉声卡，如果不存在sound驱动，启动会报错，，所以最好注释 <video> <model type=’cirrus’ vram=’9216′ heads=’1’/> </video> </devices></domain>
2、如果报什么错，查看日志# tail -f 10 /var/log/libvirt/qemu/
然后拍一些美得想哭的照片，留给老年的自己。
