Thank you,Do  you want to say the qemu does not really want to go forward with "external" snanpshots just now?Do you know why the qemu doesn't want to support it?The external snapshot is so important to our users.Thank you!

Adding support for deleting and reverting external snapshots is desired
since qemu does not really want to go forward with internal snanpshots.

The plans for fixing this are indefinite though. I'll probably work on
it but currently I'm working on '-blockdev'-izing of the qemu driver so
I can't really tell you any time frame.
