[libvirt] [RFC PATCH 0/4] Add new function about block backup

[Rudy Zhang]

Add new function about block backup, it supports the drive-backup function
in qemu, it supports three modes: full, top, incremental.

How to use it? As usual, we must do the full backup at first, if it's
successfull, next time, we can do the incremental backup, because it has
the bitmap to trace the dirty io. The incermental backup is faster.
If backup fail at some time, we must do the full backup again, only in this
way, we can keep the backup data correctly.

Rudy Zhang (4):
  Introduce virDomainBlockBackup API
  qemu drive support block backup.
  virsh: support blockbackup in virsh command
  libvirt-test: libvirt test supports drive-backup
