openstack学习笔记：Kvm基础实验环境
系统：centos7.1安装环境：桌面环境、kvm基础服务
一、关闭selinux
# setenforce 0
# sed -i 's/enforcing/disabled/g' /etc/selinux/config二、关闭iptables
# systemctl stop firewalld
# systemctl disable firewalld三、确认服务器cpu是否支持虚拟化
# grep -o 'vmx\|svm' /proc/cpuinf

1、已经安装的软件以及可以安装的软件
2、安装图形桌面
# yum -y groupinstall "X Window System" "GNOME Desktop"3、安装vncserver
# yum -y install tigervnc-server4、配置vnc
# 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.log5、使用vnc连接测试
五、安装kvm
1、安装kvm依赖包
# yum -y install qemu-kvm libvirt virt-install bridge-utils virt-manager
# lsmod |grep
kvmkvm_intel 1480810
kvm 4611261 kvm_intel2、启动libvirt服务
# systemctl start libvirtd
# systemctl enable libvirtd
这样就可以创建kvm虚拟机了
