用virtual-manager安装虚拟机

使用virt-manager基本使用

启用机管理主窗口

硬件细节窗口 配置虚拟机启动选项 附加USB设备给虚拟机准备工作 USB重定向

虚拟机图形控制台

添加远程连接

显示虚拟机细节

性能监视

实验准备

操作系统安装介质,is文件

磁盘空间准备

添加新的磁盘

创建LV

创建文件系统及挂载点

再添加新的硬盘时无需重启

[root@kvm1 scsi_host]# mkfs.ext4 /dev/vmvg/lvvm1

mount点

[root@kvm1 scsi_host]# mkdir /vm
[root@kvm1 scsi_host]# mount /dev/vmvg/lvvm1  /vm
[root@kvm1 scsi_host]# vi /etc/fstab
lts        0 0
