Title:
  Issues with qemu-img, libgfapi, and encryption at rest

Status in QEMU:
  Expired

Bug description:
  Hi,

  Encryption-at-rest has been supported for some time now.  The client
  is responsible for encrypting the files with a help of a master key
  file.  I have a properly setup environment and everything appears to
  be working fine but when I use qemu-img to move a file to gluster I
  get the following:

  
  # qemu-img convert -f raw -O raw linux.iso gluster://gluster01/virt0/linux.raw

  On and on until I get this message:

  I asked for help assuming it's a problem with glusterfs and was told
  it appears qemu-img's implementation of libgfapi doesn't call the
  xlator function correctly.
