<div dir="ltr"><div><div><div><div><div><div>Thank you for your explanation.<br></div>Infact I have already found it by trial and error.<br></div>I usually read documentation (and I have read the big opennebula documentation).<br>
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:<br>
<br></div>- difference among persistent/non persistent/volatile;<br></div>- why I need to create a template and I cannot create virtual machines directly;<br><br></div>So I wonder if there is a tutorial on using cloud systems or something similar.<br>
