Note (thanks Eric Blake): Above, if you have QEMU guest agent
installed in your virtual machine, try --quiesce option with
'snapshot-create-as' to ensure you have a consistent disk state.
About the --quiesce option. Do i need to do something inside the vm? The most
commonly would probably be a sql server running inside the vm. Do i need to
tell the sql server something about the --quiesce option i use? I read this
article here which suggests such a procedure. Okay, it's vmware, but... Is
that right?
