--------------------------------------分割线 --------------------------------------
1.在Vmware里面安装RHEL6.4
2.安装vmtools
过程略...
关闭防火墙与Selinux
[root@server ~]# service iptables stop
[root@server ~]# chkconfig iptables off
[root@server ~]# setenforce 0
[root@server ~]# vim /etc/sysconfig/selinux
SELINUX=disabled
3.配置IP地址为192.168.100.1
4.关闭NetworkManager //不关闭会影响网卡设置
[root@server ~]# service NetworkManager stop
[root@server ~]# chkconfig NetworkManager off
[root@server ~]# shutdown -h now
5.调整vmware的设置
关机状态下，点击处理器。然后在右边窗口虚拟化引擎中勾选虚拟化Inter VT-x/EPT或AMD-V/rvi(V)，确定
找到RedHat6.4安装目录，鼠标右键选择记事本方式打开Redhat6.4 64位.vmx 文件，在下面添加apic.xapic.enable = "FALSE"
6.配置YUM
7.安装KVM
[root@server ~]# yum -y groupinstall "Virtualization" "Virtualization Client" "Virtualization Platform" "Virtualization Tools"
[root@server ~]# /etc/init.d/libvirtd start
[root@server ~]# chkconfig libvirtd on
8.配置PXE
过程略
9.设置HOST主机桥接网络
[root@server ~]# cd /etc/sysconfig/network-scripts/
[root@server network-scripts]# cp ifcfg-eth0 ifcfg-br0
[root@server network-scripts]# vim ifcfg-br0
DEVICE="br0"
HWADDR=00:0C:29:D7:31:92
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Bridge"
IPADDR=192.168.100.1
PREFIX=24
[root@server network-scripts]# vim ifcfg-eth0
DEVICE="eth0"
HWADDR=00:0C:29:D7:31:92
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
BRIDGE=br0
9.可创建KVM虚拟机存储文件
[root@server ~]# mkdir -p /data/image
[root@server ~]# dd if=/dev/zero of=/data/image/vt1.img bs=10M count=1000
10.安装KVM虚拟机
[root@server network-scripts]# virt-manage
