[one-users] Open Nebula, NFS and requirements of disk space?

[Anders Branderud]

Hello!
I have read this information about required disk space for installing Open
Nebula:

"*Example*: A 64 core cluster will typically run around 80VMs, each VM will
require an average of 10GB of disk space. So you will need ~800GB for
/srv/cloud/one, you will also want to store 10-15 master images so ~200GB
for /srv/cloud/images. A 1TB /srv/cloud will be enough for this ex"

Here is my question: I have 16 computers and each of them has a harddrive of
36 GB each.
Will the disk space suffice for this? [This is how I plan to configure the
system:]
There are only two master images (i.e. approx. 20 GB).
There can be between 1 and 15 virtual machines. The virtual machines run on
the worker nodes of Open Nebula.
The master images are not cloned and they are not stored when the regular
user is finished with his/her session.

I understand that it won't work if this is necessary: "/srv/cloud/one, will
hold the OpenNebula installation and the clones for the running VMs".
How do I configure the system to not clone the running VM's, but to only to
run them on the worker nodes?

If the disk space suffices, then how do I configure the system to accomplish
the above requirements?
I plan to install the system on CentOS, using the express installation (for
NFS) provided on Open Nebula's website.

Thanks!
