Open Stack

Hello all;

I'm an experienced developer and I work at Cisco.  Chances are I've covered
the basics here,but just in case, check me.
I've followed the Kilo install instructions to the letter so far as I can
tell.   I have not installed Swift, but I think everything else, and my
installation almost works.   I'm having a little trouble with Glance.

It seems that when I attempt to create a large image (that may or not may
be the issue), the checksum that Glance records in it's DB is incorrect.
Cirros image runs just fine.  CentOS cloud works.  But when I offload and
create an image from a big CentOS install (say 100gb), nova says the
checksum is wrong when I try to boot it.

Install was on a fresh CentOS7 on new system I built, i7 32GB 7TB.  Plenty
of speed and space.   And this system is dedicated to Openstack.

Here's a little test I ran.

Thank you very much for your help.  Looking forward to getting this system
fully op and operational.
