RE: [Xen-devel] Should Qemu monitor be enabled by default

["You, Yongkang" <yongkang.you@xxxxxxxxx>]

Hi Christian and Daniel, 

I have read the original discussion about the security purpose concern for 
removing the ioemu monitor. For the CD-ROM configuration, if we only give 'r' 
readonly permission to hdc:cdrom device, user can not write to the file 
directly.

For example:
disk = [ 'file:/var/image1,hda,w', 'file:/var/boot.iso,hdc:cdrom,r' ]

Best Regards,
Yongkang (Kangkang) 永康
