Hey David,<br>
<br>
Thanks for confirming about Fedora 20. Regarding "currently libvirt
cannot start an image from gluster via libgfapi anyway(?)." Do you
mean using virt-manager you cann't see a vm image through libgfapi
and you need a fuse mount for this? But you can modify vm instance
through qemu tools and then use libgfapi.<br>
<br>
Yes, there is a way to compile latest code available compile it for
CentOS6.5. Here are the steps.<br>
<ul>
<li>We need relevant spec file and source code to build RPM. <br>
</li>
<li>Spec file can be found by extracting [1] the source RPM of
latest libvirt of CentOS 6.5 [2] or publicly available latest
RHEL6.5 libvirt src RPM [3].</li>
<li>For source we can take the source from Fedora20 [4] (again
extract from src RPM) as it will be stabler than upstream latest
code. <br>
</li>
<li>And try to create RPM using spec file of CentOS and source
code of Fedora.<br>
</li>
</ul>
<p>If you have specific questions on it , we can take help from
Kaleb, or we can contact centos-devel mailing list. I am also
working with it and if possible will provide the packages in
gluster repository[5].<br>
</p>
<p><i>However, I think we dont have enough documentation[6] on this
and we badly need documentation on this. The documentation
should have information about using libgfapi with qemu and
libvirt. May be an example with Fedora 20 or some other distros
would be good. <br>
</i></p>
<p><i>I have created a gluster wiki page[6] for this. I would
request everybody (specially in this email thread :)) to
contribute for it. </i><i>If you are new in gluster
documentation refer [7] for details</i>.<br>
