I have a node with OpenStack installed on it.
Currently I have one Ubuntu image file.
.
Can I use www.vagrantbox.es .box files for OpenStack?
I'm starting a cloud hosting company.
Vagrant now supports Docker a bit more. That's designed for production environments more so than just vagrant + VirtualBox.
I don't see why you couldn't use provided boxes for OpenStack.. but you wouldn't want it running on VirtualBox (I/O read times are abysmal )
