Sorry, I don't follow, as I said everything works until we set 
cache=none or cache=directsync in libvirt,

i.e. there is no relation with other gluster settings.

Dunno, we run qemu on the same host as gluster itself, so we have the 
same gfapi version as gluster server.

I ment dis you use C7 with Gluster 7 (or older) or C7 with the new Gluster 8.

Anyways,
if it worked before , it should run now - open an issue in github and I guess
someone  from the devs will take a  look.
