hi ,everyone!
I am a newcomer to Libvirt, and I don't know if it's a native question,
I create snapshots of virtual machines that use encrypted disk, The console gave me the
following error:

Hi, encrypted snapshots will be possible only when using the new
'blockdev' approach to configuring disk sources. The work on that is
almost done. It's possible that the next upstream release will support
it.
