It is a different feature ;)
shouldn't that be part of the snapshot improvements design?
What Miki is looking for, miki please correct me if i am wrong, is the
ability to change VM configuration while the VM is running and expect
the changes to apply starting from the next VM run.
For the above feature to be 'complete' Miki wants to be able to view
what is the VM current configuration (the one used when the VM started)
and what is the configuration for the next run.
After the VM is stopped you have only one configuration (the one for the
I guess i can see why you associated it with snapshots, as we can look
at it as a temporary VM configuration snapshot, but i think it is
another functionality (especially in UI/client perspective).
