Centos6.6 kvm install

一、安装kvm

1、先在blos中,开启vt-d功能

2、检查vmx看,是否开启vt-d

[[email protected] ~]# egrep --color ‘(vmx|svm)‘ /proc/cpuinfo

3、yum install qemu-kvm virt-manager python-virtinst qemu-kvm-tools libvirt -y

4、配置桥接网卡

[[email protected] ~]# vi  /etc/sysconfig/network-scripts/ifcfg-br0

[[email protected] ~]# vi  /etc/sysconfig/network-scripts/ifcfg-eth0
E=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=none

#重启网络服务

service network restart

#查看ip

[[email protected] ~]# ifconfig

5、启动libvirtd服务

/etc/init.d/libvirtd start
/etc/init.d/libvirtd status

6、安装虚拟机

[[email protected] ~]# cd /opt/

#创建分区
qemu-img create -f raw /opt/kvm.raw 10G

#加载镜像
dd if=/dev/cdrom of=/opt/centos66.iso
ls -lsh /opt/centos66.iso

#安装centos6.6
virt-install --virt-type kvm --name centos6.6 --ram 1024 --cdrom=/opt/centos66.iso --network network=default --graphics vnc,listen=0.0.0.0 --noautoconsole --os-type=linux --os-variant=rhel6 --disk path=/opt/kvm.raw

#清空iptables
iptables -L
iptables -F

备注:必须清空防火墙,否则无法连接TightVNC软件

7、查看监听端口

[[email protected] ~]# netstat -ntlp

[[email protected] ~]# ps aux | grep kvm

8、安装windows连接vnc软件
