The biggest question here is if the OS is using systemctl or not. Cl7 boots
extremely quick but our cl6 instances take up to 90 seconds if the cluster
has work to do.
I know there a lot to do in the init as well with boot profiling etc that
could help.

Guys Thanks a lot for your response.
We are running OpenStack Juno + Ceph 94.5
@Jason Dillaman Can you please explain what do you mean by "Glance is
configured to cache your RBD image" ? This might give me some clue.
Many Thanks.

Your glance images need to be raw, also. A QCOW image will be
copied/converted.

If Nova and Glance are properly configured, it should only require a quick
clone of the Glance image to create your Nova ephemeral image. Have you
double-checked your configuration against the documentation [1]? What version
of OpenStack are you using?
To answer your questions:
> - From Ceph
I'm not sure what's normal, but I'm on Openstack Juno with ceph .94.5 using
separate pools for nova, glance, and cinder. Takes 16 seconds to start an
instance (el7 minimal).
Everything is on 10GE and I'm using cache tiering, which I'm sure speeds
things up. Can personally verify that COW is work
