On the Gluster site there is a QEMU repo I'll send you the link latter today. But essentially CentOS doesn't include the Gluster client or libraries so they can't compile against it.<br>I'm not sure why CentOS and Scientific Linux don't include it but I think it might just be an over site since Gluster 3.4 is new set of packages which were added in the latest release of RHEL 6.<br>In truth you can simply unpack the source RPM and rebuild it with Gluster support its not difficult but I don't remember the flags you need to pass the rpmbuild command off the top of my head. That said I'd probably use the ones off the Gluster site any way. <br>If you are using Gluster 3.5 the ones included in RHEL are incompatible because Gluster still has large API changes between minor releases and they were compiled against 3.4. <br><br>Also Gluster 3.5 is a brand new release so I wouldn't rule out the possibility of a bug. So if the Gluster enabled QEMU rpms don't help you may need to inquire on the Gluster mailing list.<br><br><span style="font-family:Prelude, Verdana, san-serif;"><br><br></span><span id="signature"><div style="font-family: arial, sans-serif; font-size: 12px;color: #999999;">-- Sent from my HP Pre3</div><br></span><span style="color:navy; font-family:Prelude, Verdana, san-serif; "><hr align="left" style="width:75%">On May 12, 2014 8:58, Tobias Honacker <tobias@honacker.info> wrote: <br><br></span><div dir="ltr">I've got the same issue using the same versions as Korsaks, using CentOS 6.5, too.<div>I could launch vms with gluster <span style="color:rgb(51,51,51);font-family:arial,sans-serif;font-size:13px;line-height:17px">block backend driver using the standard package of libvirt from centos repo.</span></div>
