Hi,
QEMU uses pkg-config to get the version of libgfapi and accordingly enable features. Currently, it checks for version 3 for base libgfapi support, version 5 for discard API support and version 6 for zerofill API support.
However with recent commit c2b09dc87, libgfapi version changed from 6 to 0.0.6. So the question now is:
Will there be any major/minor release of GlusterFS that will go out with libgfapi version as 6 which QEMU should support or should QEMU just switch over to using 0.0.6 ?
