本文深入探讨了虚拟化技术，通过两个实例详细介绍了全虚拟化和半虚拟化的配置文件，包括核心参数设置、虚拟机启动方式及网络、存储配置。

1. 全虚拟化配置文件

exam1:

name = "new"
kernel = "/usr/lib/xen/boot/hvmloader"
memory = 1024
builder = "hvm"
device_model = "/usr/lib64/xen/bin/qemu-dm"
boot = "d"
disk = ['file:/mnt/iso/CentOS_5.5.64bit.iso,hdc:cdrom,r',
'file:/mnt/img/new.img,sda,w']
vif = ['mac=00:01:01:00:00:03, bridge=xenbr0']
dhcp="on"
vnc = 1
vncdisplay = 7

pae = 1

exam2:

kernel = "hvmloader"
builder='hvm'
memory = 512
name = "fedora"
vif = [ 'type=ioemu, mac=00:c0:9f:78:35:a7, bridge=xenbr0' ]
disk = [ 'file:/root/domU.img,xvda,w','file:/root/Fedora-14-i386-DVD.iso,xvdc:cdrom,r' ]
device_model = 'qemu-dm'
boot="cd"
vnc=1
vnclisten="127.0.0.1"
vncconsole=1
vncpasswd=''
serial='pty'
usb=1
usbdevice='tablet'

###xm create xen.cfg

###vncviewer localhost:7

2. 半虚拟化配置文件

kernel = "/mnt/xen/vmlinuz"
ramdisk = "/mnt/xen/initrd.img"
name = "test"
uuid = "14d7fb2c-3ef7-ce3e-7e73-bd6e4e082887"
maxmem = 512
memory = 512
vcpus = 1
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
disk = [ "tap:aio:/mnt/img/new.img,xvda,w" ]
vif = [ "mac=00:16:3e:10:e4:53,bridge=xenbr0,script=vif-bridge" ]

###xm create -c xen.cfg

注意点：kernel和ramdisk取自iso/images/xen目录下。
