&gt; Hi all,I was wondering if anyone might be able to speak about using IBM&#39;s GPFS<br>
filesystem as a means of storing virtual guests in a clustered environment with<br>
CentOS as the nodes and KVM as the hypervisor?<br>
<br>
Hi Adam,<br>
I use GPFS as my filesystem for my Centos-Xenvirtual environment.<br>
<br>
The Virtual servers are converted Compute nodes, running Centos 5.4 with Xen<br>
3.4.2 and have Infiniband connectivity to the NSD servers.  The VM&#39;s all live on<br>
the GPFS filesystem.  This has worked pretty well, the disk performance of the<br>
VM&#39;s has been good when using the GPL paravirt drivers (my VM&#39;s are windows<br>
server 2003).<br>
