Sorry i have to ask some questions regardig your dummy:

- Why do we name the "source": volume instead of source?

- What is the meaning of these lines:

# pvesh examples
# cd /nodes/localhost/storage/local/content
# pve:/> create local:103/vm-103-disk-1.raw -target 
local:103/vm-103-disk-2.raw
# pve:/> create 103/vm-103-disk-1.raw -target 103/vm-103-disk-3.raw

- What has to be checked? Or just if $src_volid and $dst_volid are set?
# do all parameter checks first

- # then do all short running task (to raise errors befor we go to 
background)
This should be creating the target right?

Thanks and sorry. Integrating the next idea (i have some ;-) ) will be a 
lot easier for me with your help. So i don't have to bother you.

Stefan
