linux 虚拟机 xen安装

安装环境： VM6 安装centos 5  然后在centos 5 下面安装虚拟机xen 其次在xen虚拟机上安装另外一个linux centos的虚拟机系统 就如同VM6上安装windows系统，另外在此windows下面安装VM软件 其次在vm下安装另一个windows系统类似 1>首先在VM6中建立虚拟机,添加2块磁盘，一块安装宿主机，一块预留安装XEN虚拟机。 2>在宿主机中YUM安装xen包和vsftp包。（最好在安装系统的时候就把这两个组件装上，也可以通过添加/删除程序进行安装，不过要修改yum配置）   [root@localhost ~]# yum -y install xen   [root@localhost ~]# yum -y install vsftpd.i386                   安装 yum install gnome-applet-vm.i386          修改grub启动菜单已xen内核启动          vi /boot/grub/grub.conf           #boot=/dev/sda          default=0(1修改为0启动xen内核)

 

3>用xm list 命令查看Domain是否已经启动。   [root@localhost ~]# xm list   Name                                      ID Mem(MiB) VCPUs State   Time(s)   Domain-0                                   0      778     1 r-----     85.4   4>将cdrom挂载到FTP目录，将ftp匿名用户开启。   /etc/init.d/vsftpd start  #启动ftp   [root@localhost ~]# mount /dev/cdrom /var/ftp/pub/ #挂载光盘到ftp下  mount: block device /dev/cdrom is write-protected, mounting read-only   5>用xm命令行建立虚拟机   [root@localhost ~]# virt-install  （新版本的xen需要加参数 --prompt，有设置硬盘大小参数，旧版本没有这个参数   What is the name of your virtual machine? vm1   #虚拟机的名字vm1   How much RAM should be allocated (in megabytes)? 400  #为虚拟机分配内存400M 最低256M   What would you like to use as the disk (file path)? /dev/sdb1 #sdb为第二块硬盘   Would you like to enable graphics support? (yes or no) no #不启用图形化支持   What is the install location? ftp://192.168.1.237/pub/ #填上本机FTP地址，前提是CDROM已经挂载到这个FTP目录，并开启了匿名用户。    可以看到安装文件内核已经开始启动！  Starting install...
