Interesting indeed. Does LVM span across multiple storage servers?<div><br></div><div>That is another issue and im not trying to open up a can of worms but what is the advantage of using KVM over xen or even citrix xen server<br>

Sure. With virtualisation by KVM.

<div><br></div><div>Say if you have 5 machines. Each machine has a RAID volume. You can use LVM to carve up this volume so that one VM can use half of it for Gluster and another VM could use the other half of it for hadoop.</div>

<div>Sadly I have no experience in a cluster environment :( I do have my old laptop and hopefully have a 2nd one soon. Is it possible to have a mixed cluster with gluster or hadoop or any other clustering technology which is a hetrogenous cluster in terms of linux machines and mac machines and if someone wants windows machines?</div>

not as efficient as gluster I would venture.<div class="gmail_extra"><br><br><div class="gmail_quote">2012/11/27 Jonathan Aquilina <span dir="ltr"><<a href="mailto:eagles051387@gmail.com" target="_blank">eagles051387@gmail.com</a>></span><br>
