[ovirt-users] Re: Libgfapi considerations

The bug has been closed wontfix for a lack of perceived progress on the issue : https://bugzilla.redhat.com/show_bug.cgi?id=1633642 https://bugzilla.redhat.com/show_bug.cgi?id=1484227 However when following the related opened bugs in qemu, i get the feeling things are getting ready to have libgfapi working in a replica 3 cluster. See : https://bugzilla.redhat.com/show_bug.cgi?id=1465810 I wish someone would reopen those closed bugs in order for that issue not being forgotten.
