[one-users] No system datastore with enough capacity form the VM

Thank you for your explanation.
Infact I have already found it by trial and error.
I usually read documentation (and I have read the big opennebula
documentation).
But, as I have already said in an other post, probably because I am new to
cloud virtualization systems (I am used to standard virtualization like
vmware), even reading documentation I cannot understand easily several
concepts:
- difference among persistent/non persistent/volatile;
- why I need to create a template and I cannot create virtual machines
directly;
So I wonder if there is a tutorial on using cloud systems or something
similar.
Thanks again,
Mario
