输入命令virsheditwinxp_sp2修改如下

   disktype‘file‘device‘disk‘      drivername‘qemu‘type‘qcow2‘cache‘writeback‘/ 

     sourcefile‘/polydata/image/winxp_sp2.qcow2‘/ 

     targetdev‘hda‘bus‘ide‘/ 

     addresstype‘drive‘controller‘0‘bus‘0‘target‘0‘unit‘0‘/ 

   /disk 

   disktype‘file‘device‘cdrom‘ 

     drivername‘qemu‘type‘raw‘/ 

     sourcefile‘/tmp/virtio-win-0.1.96.iso‘/ 

     targetdev‘hdc‘bus‘ide‘/

   /disk 

   disktype‘file‘device‘disk‘  

   drivertype‘qcow2‘cache‘writeback‘/     

     sourcefile‘/tmp/test.img‘/     

     targetdev‘vdc‘bus‘virtio‘/  

   /disk 

   interfacetype‘bridge‘ 

     macaddress‘52:54:00:33:a4:19‘/

     modeltype‘virtio‘/ 

     addresstype‘pci‘domain‘0x0000‘bus‘0x00‘slot‘0x03‘function‘0x0‘/ 

   /interface

其实原始disk不用修改只需要添加virtio-win.iso的cdrom、virtio类型的临时disk以及将网卡修改为virtio类型。

2.创建磁盘qemu-imgcreate–fqcow2/tmp/test.img1G将驱动复制到/tmp/virtio-win-0.1.96.iso驱动下载地址 https://fedoraproject.org/wiki/Windows_Virtio_Drivers可以打开https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/下载不同版本的驱动

3.更新驱动virshstartwinxp_sp2使用vnc连接系统会提示找到新硬件弹窗安装驱动的窗口SCSI和网卡安装时尽量不要自动搜索而是手动搜索不同的操作系统路径如下
