解释：guest01代表需更改的虚机名，*.iso为需添加的iso

      如果报错：

virsh # attach-disk ICCS-PM /gfs/sysdisk/installdisk-pool/cn_win_srv_2003_r2_enterprise_with_sp2_vl_cd2.iso hdc --driver file --type cdrom --mode readonly

错误：Failed to attach disk

错误：internal error unsupported driver name 'file' for disk '/gfs/sysdisk/installdisk-pool/cn_win_srv_2003_r2_enterprise_with_sp2_vl_cd2.iso'

取消--driver file参数即可

Add CDROM:

#virsh

attach-disk guest01 /root/disc1.iso hdc --driver file --type cdrom

--mode readonly

 

Change CDROM:

attach-disk guest01 /root/disc2.iso hdc --driver file --type cdrom

--mode readonly

 

Remove CDROM:

attach-disk guest01 " " hdc --driver file --type cdrom

--mode readonly
