Description John Snow 2019-01-24 00:27:19 UTC

Description of problem:

The pull-model incremental backup API still uses commands like "x-block-dirty-bitmap-disable" and several others. The API should be finalized for use by Libvirt/RHV and others.

Version-Release number of selected component (if applicable):

Seen in 7.7's qemu-kvm-rhev-2.12.0; fixed upstream in QEMU 3.1 development branches.
