 There has been no drop in goal. There are many parts to "supporting a VM
workload". The goals listed for 3.3 are definitely met - to make VMs work
good enough (fix self-heal locking issues, some FUSE upstream work for
supporting O_DIRECT etc.) However, for 3.4 we have bigger goals of
supporting VM image use case in a much better way - libglusterfsclient
integration for QEMU etc. This was what Amar was referring to. I hope I
clarified your doubt, and apologies for the confusion.
