openstack学习笔记：Kvm基础实验环境

sdoghds88888

系统：centos7.1

安装环境：桌面环境、kvm基础服务

一、关闭selinux

[root@localhost ~]# setenforce 0
[root@localhost ~]# sed -i 's/enforcing/disabled/g' /etc/selinux/config

二、关闭iptables

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld

三、确认服务器cpu是否支持虚拟化

[root@localhost ~]# grep -o 'vmx\|svm' /proc/cpuinf
vmx
vmx
vmx
vmx
vmx
vmx
vmx
vmx

四、安装桌面

1、已经安装的软件以及可以安装的软件

2、安装图形桌面

[root@localhost ~]# yum -y groupinstall "X Window System" "GNOME Desktop"

3、安装vncserver

[root@localhost ~]# yum -y install tigervnc-server

4、配置vnc

[root@localhost ~]# vncserver
You will require a password to access your desktops.
Password:
Verify:
xauth:  
file /root/.Xauthority does not exist
New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1
Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost.localdomain:1.log

5、使用vnc连接测试

五、安装kvm

1、安装kvm依赖包

[root@localhost ~]# yum -y install qemu-kvm libvirt virt-install bridge-utils virt-manager
[root@localhost ~]# lsmod |grep
kvmkvm_intel         148081  0
kvm             461126  1 kvm_intel

2、启动libvirt服务

[root@localhost ~]# systemctl start libvirtd
[root@localhost ~]# systemctl enable libvirtd

这样就可以创建kvm虚拟机了
