"You can however force the write back to the raw disk images by using
the commit monitor command (or <C-a s> in the serial console)".

But the issue is that I want to keep writes in temporary file and also use 'loadvm' to load

CPU and device states.  When I invoke qemu with -loadvm and -snapshot both options,

then qemu doesn't load the VM state and does a normal boot.
