<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Hi David,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Since you mention this is for testing and learning the technology, I’d go with option #2. You’ll lose some performance but that shouldn’t matter for your purposes, and you’ll gain a lot
of flexibility. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">KVM is a basic building block for oVirt and Openstack. It’s a valuable skill set to have, even outside of RH based distributions. It’s fairly simple to troubleshoot, there’s not so many
moving parts. It’s like a reliable old car with a stick shift and roll-up windows.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">If you only have one physical server at your disposal and you choose option #1, then you have to use a self-hosted engine. I personally don’t like the self-hosted engine. That could be
due to some bad experiences early in its history, and maybe it’s much improved with oVirt 4.x. But I’d much rather have a plain old KVM VM (for the oVirt engine) that I can make a clone or snapshot of. That has saved me from rebuilding many times.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">I’ve never used GPU pass-through; hopefully someone else can address that.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Yes, CentOS is your best bet; stick with the default kernel. You could use Fedora if you’re adventurous but I don’t recommend it. You’ll have the best experience if your environment is
close to what is supported in the commercial product, RHV. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Take advantage of the official RHV documentation, most of which is applicable to oVirt upstream.
