kvm虛擬化學習筆記(一)之kvm虛擬化環境安裝

最近訪客

1.操作系統安裝

本文采用OEL6.3X64操作系統，也可以採用RHEL/CentOS6.x。

(1)修改內核模式爲兼容內核啓動

(2)關閉selinux，重啓後生效

(3)關閉防火牆

1 2	chkconfig ip6tables off chkconfig iptables off

(4)重啓

1

# reboot

2.虛擬化環境配置

(1)查看是否支持虛擬機

說明1:半虛擬化是不能運行與安裝KVM虛擬機的，  我用的是workstation 安裝centos6.3 所以還需要把centos6.3的虛擬化功能打開，

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環境

OEL6.3已經配置好源，只需要開啓即可。

(3)安裝kvm軟件包

1	#yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v

過程略。

補充安裝kvm虛擬化一些管理工具包

1	#yum -y install libguestfs-tools

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55

3.查看虛擬化環境

(1)查看虛擬機環境

(2)查看kvm模塊支持

(3)查看虛擬工具版本

 

4.手動配置虛擬網橋

(1)關閉networkmanager服務

(2)創建br0網橋

1 2 3 4

[root@node1~]#cd  /etc/sysconfig/network-scripts/ [root@node1network-scripts]#cp ifcfg-eth0 ifcfg-br0 [root@node1network-scripts]# [root@node1network-scripts]#

(3)關閉了networkmanager服務之後，才能通過servicenetworkrestart管理網絡。

(4)查看網橋br0.

(4)查看網橋

到此kvm虛擬化環境安裝完畢。
