This patch series supercedes an earlier series:

Just before posting those patches (and leaving for 10 days of
holiday), Paolo Bonzini suggested an alternate XML representation
(noted in that original message), which has since been discussed and
agreed on as the proper way to go. These new patches implement that
alternate method:
<disk type='block' device='disk' dev='/dev/sda'> <!--
SG_IO off -->
<disk type='block' device='lun' dev='/dev/sda'> <!--
SG_IO on -->
Hmm, won't this force admins to rewrite their domain definitions ?
Some admin may need to reflesh 100s of domain defintions when he upgrade
distro...
How about
<disk type='block' device='disk' dev='/dev/sda'> <!--
SG_IO on -->
<disk type='block' device='sdisk' dev='/dev/sda'> <!--
SG_IO off -->
(sdisk = secure disk)
and make 'sdisk' as default ?
Thanks,
