[libvirt] [PATCH 1/9] qemu: monitor: Add new fields for 'block-stream' command
Peter Krempa

Mon Jun 24 15:54:48 UTC 2019
Allow using the node name to specify the base of the 'stream' operation,
allow specifying explicit job name and add support for delayed dismiss
of the job so that we can reap the state even if libvirtd was not
running when qemu emitted the job completion event.
