<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>It is being worked on (the split/cleanup) ;)<BR>
Along with making devstack resemble something more like the rest of openstack (python)....<BR>
Testing is always helpful @ <a href="https://github.com/yahoo/Openstack-Devstack2">https://github.com/yahoo/Openstack-Devstack2</a> ;)<BR>

</SPAN></FONT><BLOCKQUOTE><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Thanks for your comments. I don't have any users, images, etc. to<BR>
worry about, I didn't go that fat to create users and images.<BR>
<BR>
I re-run stack.sh and horizon and keystone were running; I lunched an<BR>
instance then tried to access<BR>
<a href="http://myServer/nova/access_and_security/">http://myServer/nova/access_and_security/</a> but machine crashed and I<BR>
have to reboot it!<BR>
<BR>
I think stack.sh should be divided into two scripts one to install<BR>
devstack and another to start/stop/restart services.<BR>
<BR>
Thanks<BR>
