<br>
snapshot are meant to be backups.<br>
I would not install software on a machine, and then use the snapshot<br>
as a glance image to start many new instances.<br>
<br>
you could just create machines with a clean glance image and install<br>
the necessary software with ansible/puppet<br>
<br>
if the installation time at boot is too long, you could create glance<br>
images with the software you need with the diskimage-builder creating<br>
a new dib.<br>
<br>
Look at this example of a ubuntu glance image with zeppelin and spark<br>
preinstalled:<br>
