In the source code,i saw "alias=<path to image file>" | :cobdX
and the following example:"hda1=rootfs.img #(cobdX automaticly  from first free)"  . If cobd0 is free,then hda1 is the same with cobd0. Does alias name make any sense ? I'm a new-bie.@@.

I have modified the "cobd.c" to support the vmdk file,but I haven't resolve the "alias" problem, and do not support  "async".Very depressed. .@@.
