Correct. oVirt up until now didn't use libgfapi because of missing features (e.g. live snapshot). It seems that now all those gaps have been fixed and we're trying to re-enable libgfapi. I just mentioned that I uploaded an el6 build here: https://fsimonce.fedorapeople.org/vdsm-libgfapi/ and sources here (to rebuild on fedora): https://fsimonce.fedorapeople.org/vdsm-libgfapi/source/ Let me know if the most of you are using fedora and I'll make a build on fedora as well. Please let me know how it goes. Thanks,
