Yes, thanks for mentioning puppet, we have foreman for the bare metal systems. I was looking something like preboot hook script, to mount the /dev/sda and copy some stuff there. Is it possible to do that with cloud-init/sysprep?

thanks,the downscaling is important for me,

1) clone from actual vm(super slow,even if it is 20GB OS, needs more investigation,nfs is bottle neck) 2) start it with dhcp, 3) somehow find the ip 4) sync parameters between running vm and new vm. looks that everything might be possible with the python sdk... are there some examples or tutorials with cloudinitscripts?
