Hi,<br><br>It all depends on the workload you will execute and performance you will expect.<br>You will have to plan the amount of CPU and RAM depending on the number of VMs you will run concurrently, and the requirements of the virtualized services.<br>
The same goes for disk, it will depend on the number of images you will need to store.<br><br>The only hardware requirement is that the CPU must have virtualization extensions if you plan to install KVM.<br>Xen does not require these extensions, but you will be limited to paravirtualization. This may not be a problem to you, but you will for example lose the possibility to virtualize Windows machines.<br>
<br>As for the OS, it will be easier to configure everything in one the distributions with official packages [1], but any modern Linux distribution should work.<br>OpenNebula can be configured to use the frontend (main machine) as the only host (virtualization physical machine) without any problem. You may need a second host if you need to experiment with migrations or scheduling policies...<br>
<br>I know this is not really conclusive, but it is more a matter of adapting OpenNebula to your requirements than the other way around.<br><br>Regards.<br><br>[1] <a href="http://opennebula.org/software:software">http://opennebula.org/software:software</a><br clear="all">

Hello everyone!<br><br>I'm new here, but hopefully will try to be a regular member in the next few months.<br>To start with, I have a very simple question: what are the system requirement for a machine on which I'm trying to install OpenNebula? Since I will be working in partnership with an IT company on my project, they need to know the parameters of the machine I'm going to work on (including OS, CPU performance, memory, all necessary software, etc.) This information was not specified on the official website, that's why I'm trying here.<br>
<br>Also, do I need further physical machines (worker nodes), in order to experiment with
OpenNebula, or could I just install several VM's on the already existing (main, cluster) node? I need to know how many physical PC's I need. In the starting phase, I only need to experiment with the cloud, and see what and how happens, possibly through integrating a simple appication (so you don't have to think of very complex stuff).<br>
<br>I think these questions are really simple to answer if you have basic knowledge in the domain, so hopefully someone will be helpful enough to provide me with an answer.<br><br>Thank you in advance.<br><br>Hope you all have a good day,<span><font color="#888888"><br>
