Open Stack

I have originally brought this on IRC, but though this place might be  
better adequate.
As part of the storlets functional tests Jenkins job, we do a docker  
pull from docker hub.
This operation fails many times, and requires many "recheck"s (we run  
this with every 'git review').
One solution we were thinking of is having a VM image that contains  
the Docker image we need (e.g. saved using docker save), thus  
bypassing the need to do "docker pull". Is that possible? I realise  
that so far probably devstack is the only example making a special  
tailored image.

Many thanks,
Eran
