<p class="MsoNormal">I have a fundamental question which, hopefully, someone here can answer.<o:p></o:p></p>

<p class="MsoNormal">I will ask by presenting a probably non-realistic example.<o:p></o:p></p>

</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Lets say I have 10 compute nodes as separate physical machines with 1 core each. Without taking into account the ability to overload each core (the famous 16:1) I would like to know:<br>
<br>
<b>Can i use all the 10 cores to create a single instance that takes advantage of the all the core pool?</b> Or the fact that each compute node has its own hypervisor limits the core usage of each instance to one? Are the whole resources abstracted and seen
as one or not?<o:p></o:p></p>
