Dear all the members,<br><br>I have tried to implement OpenNebula for a
couple weeks already but still not successful implemented. Anyway, I'm
here not to mention about my problems because I have read some other
posts that has the same problem as me and still couldn't solve my
problems. Well, I am doing master course. I study at Korea Aerospace
University (in Korea). I'm interesting on Cloud Computing. Currently,
I'm interesting on OpenNebula, so I want to implement and experience
about it. But I have some doubt, so please can anyone help me:<br><ol><li>Why do we need Clustering for OpenNebula?</li><li>If it is really important for OpenNebula, what kind of clustering architecture do I need before implement OpenNebula?</li>
<li>Is
it a disk-less clustering or dependent machines that already have their
own operating system installed before joining the cluster?</li><li>Is there any middle-ware for this clustering?</li><li>What is the appropriate operating system for OpenNebula?</li><li>Why do we need NIS?</li><li>Does OpenNebula requires VT process because for example KVM need a VT processor in order to load the kvm_intel module?<br>
</li><li>For example, if I decide to use KVM, does KVM must be installed in all the nodes (front-end and cluster nodes)?</li><li>What I was so wondering is in the red text of this sample virtual machine template:<br></li>
