[Gluster-users] Gluster 3.5 problems with libgfapi/qemu

[Ivano Talamo]

Hi Jae,

starting the vm works fine, but only in the old-way, ie. with the path 
to the mounted volume.
If trying to start with the libgfapi the virsh start commands waits 
forever (is blocked on a futex).

Maybe I should leave the libgfapi for the future.

Thanks,
Ivano
