Hi Salman,

Have you checked the instances console logs? (i.e `nova console-log
$SERVER_UUID` or the "logs" visible in Horizon)

If there is nothing showing in the console logs, then you need to make
enable a serial console in the image and then re-upload it to glance.

A quick search for a how to do this when RHEL shows this guide - which
looks complete to me, but I'm an Ubuntu guy ;)

Thanks,
Kiall
