kvm虚拟化学习笔记(一)之kvm虚拟化环境安装
最近访客
1.操作系统安装
本文采用OEL6.3X64操作系统，也可以采用RHEL/CentOS6.x。
(1)修改内核模式为兼容内核启动
(2)关闭selinux，重启后生效
(3)关闭防火墙

chkconfig ip6tables off
chkconfig iptables off
|
(4)重启

|
# reboot
|
2.虚拟化环境配置
(1)查看是否支持虚拟机
说明1:半虚拟化是不能运行与安装KVM虚拟机的， 我用的是workstation 安装centos6.3 所以还需要把centos6.3的虚拟化功能打开，
修改centos.vmx文件加入如下字段：“
| nce.enable = "TRUE" hypervisor.cpuid.v0 = "FALSE" featMask.vm.hv.capable ="Min:1" vhv.enable = "TRUE" |
|
1
|
#egrep
'(vmx|svm)'
--color=always /proc/cpuinfo
|
(2)配置yum环境
OEL6.3已经配置好源，只需要开启即可。
(3)安装kvm软件包
|
1
|
#yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v
|
过程略。
补充安装kvm虚拟化一些管理工具包
|

|
#yum -y install libguestfs-tools

(3)关闭了networkmanager服务之后，才能通过servicenetworkrestart管理网络。
(4)查看网桥br0.
