You can omit the memory snapshot specification and then it will be
completely omitted.
have a use case to restore from the snapshot snapshot so hopefully
this
approach will not cause any issue.
The issue is that if you don't pause the VM the state between the memory
state captured in the dump and the disk images will not be completely
consistent.
Additionally the same applies for using --live. The memory image itself
may be inconsistent.
If you want to be sure that everything is consistent, you should pause
the VM.
