libvirt users - Feb 2018 - Re: Ask question

Dear 


             Recently,I am interested in libvirt,but I found the libvirt
does't support revert and delete the external snapshot which the raw disk
based guest.My libvirt and qemu release are both 3.2.0.So I have a question,the
community how to solve it,if have any plans about it.Can you tell me more about
it?Thank you very much.

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.

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!

letter.Thanks for your answer.

Along with what Peter wrote, here's some notes about what you can do
currently to revert to an external snapshot:
