[iyunv@KVM3 yum.repos.d-bak]# yum clean all
第三步：安装所需要的虚拟化包
[iyunv@KVM3 network-scripts]# yum grouplist
[iyunv@KVM3 network-scripts]# yum groupinstall -y 'Virtualization' 'Virtualization Client' 'Virtualization Platform' 'Virtualization Tools'
第四步：ntsysv 管理开机自启动服务
第五步：关闭selinux服务
[iyunv@KVM3 yum.repos.d-bak]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
