Hi,
I make a patch added "--nodiskcopy" option for virt-clone.
When this option is specified, only changing and defining
a XML is done, and read/write copying is not done.
When a user wants to use a ready-made snapshot product and so on
not a normal copy(read/write) at the time of device copying, I
think that this option is effective. It may be faster than
normal copying.
A user uses in the following.
1)Take snapshot
A user takes snapshot which becomes R/W volumes
(e.g. split-mirror way). It depends on a product.
2)Take clone having --nodiskcopy option
#virt-clone -o original -n clone -f /dev/snapshot_sysvol
-f /dev/snapshot_data1
-f /dev/snapshot_data2
--nodiskcopy
