  bandwidth optional Copying bandwidth limit in MiB/s.
  base optional Stop at a specific backing image instead of flattening the entire chain.

Usage examples

virsh # blockpull example-domain vda
Start populating vda from its backing image chain and return immediately.
virsh # blockpull example-domain vda --wait
Populate vda from its backing image chain and wait for the operation to complete.
virsh # blockpull example-domain vda 0 /path/to/backing.img
Start populating vda from its backing image chain up to /path/to/backing.img and return immediately. /path/to/backing.img and its backing images will not be flattened. Note that the 0 means unlimited bandwidth and is necessary because bandwidth and base are positional arguments.
