centos6.6搭建kvm环境并新建安装centos6.6的虚拟机

一、真机安装centos6.6系统（桌面最小化安装）真机：09

1.真机安装centos6.6系统

[root@localhost~]#cat/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

HWADDR=DC:0E:A1:7E:EF:F4

TYPE=Ethernet

UUID=65aee880-3e4d-4214-966f-e56acd534a2d

ONBOOT=yes

NM_CONTROLLED=no

BOOTPROTO=none

IPADDR=09

NETMASK=

GATEWAY=

DNS1=0

[root@localhost~]#ifconfig|head-2

eth0Linkencap:EthernetHWaddrDC:0E:A1:7E:EF:F4

inetaddr:09Bcast:55Mask:

[root@localhost~]#/etc/init.d/iptablesstop

[root@localhost~]#chkconfigiptablesoff

[root@localhost~]#vim/etc/sysconfig/selinux

SELINUX=disabled

[root@localhost~]#setenforce0

[root@localhost~]#ping

PING(2)56(84)bytesofdata.

64bytesfromlocalhost(2):icmp_seq=1ttl=53time=4.66ms

[root@localhost~]#yumrepolist

repolist:7,499

2.真机检查系统是否支持kvm（两个条件）

a)系统是x86的

b)CPU支持虚拟化技术，使用命令：egrep'vmx|svm'/proc/cpuinfo

如果看到有输出结果，即证明cpu支持虚拟化。同时特别注意需要检查BIOS中是否开启VT，如果没有启用，虚拟机将会十分慢。

[root@localhost~]#uname-a

Linuxlocalhost.localdomain2.6.32-504.el6.x86_64#1SMPWedOct1504:27:16UTC2014x86_64x86_64x86_64GNU/Linux

[root@localhost~]#egrep'vmx|svm'/proc/cpuinfo

flags :fpuvmedepsetscmsrpaemcecx8apicsepmtrrpgemcacmovpatpse36clflushdtsacpimmxfxsrssesse2sshttmpbesyscallnxrdtscplmconstant…………有输出

二、真机安装kvm环境

1.真机安装kvm环境

[root@localhost~]#yum-ygroupinstallVirtual*

[root@localhost~]#lsmod|grepkvm#检查是否开启成功
