Yes it makes sense to have /var/lib/glance/images and
/var/lib/nova/instances/_base on the same network file system. But Quantum
network node being a bottle neck today, would the benefits be nullified by
a choked network?

Was that to disable injection at startup?
No, NBD is just slow and unreliable for some reason. Disabling it made
my users happy. I haven't had time to find out why NBD is so horrible.
Eventually I would like to see /var/

No, but if you have multiple compute nodes you will want to have them
all share /var/lib/nova/instances on a fast NF

Thanks for the response. I have the images as .img in the web server which

Hi,
I have a Folsom 2012.2 3 nodes setup like the one specified at
https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/master/OpenStack_Folsom_Install_Guide_WebVersion.rst.
Each node has a 1Tb hard disk with no raid.
Be it the image creation or the Instance creation, takes a long t
