RHV: Adapt to qemu-kvm-rhev RHEL 8 packaging layout changes
Last modified: 2017-11-22 02:34:20 EST
qemu-kvm-rhev packaging is being changed as described in BZ 1425820. We expect this to be a compatible change, but we also think this could give the RHV team an opportunity to improve their packaging as well.

We now have modularization of the block layer in QEMU (bug #1378536) and libvirt (bug #1378540), but the QEMU packaging layout in RHEL might need changes for us to fully benefit from the changes.
For example, it should be possible to install QEMU without Gluster or Ceph block drivers (each brings a large number of dependencies).
BTW, I have not investigated this, but I have a report from Peter Krempa (libvirt) that "QEMU still can't be installed without gluster". I'm opening this BZ to request further investigation on what can be improved or changed in our packaging layout.

The reason to modularize the block layer in QEMU is to allow smaller/minimal installations of QEMU, with two primary use-cases:
1. Allow the split of the QEMU package, bringing less dependencies to a minimal installation. This is particularly important for the case of remote storage drivers, such as Ceph and Gluster, which usually link to and require external libraries and tools.
2. Faster startup of QEMU, with less drivers to load.

Let's leave this for RHEL-7.5, so we have enough time to test it. We'll also need clones of this BZ for RHV and OSP.
