The aim of pstore device is to provide a bit of NVRAM storage for guest kernel to record oops/panic logs just before the it crashes. Typical usage includes usage in combination with a watchdog so that the logs can be inspected after the watchdog rebooted the machine. While Linux kernel (and possibly Windows too) support many backends, in QEMU there's just 'acpi-erst' device so stick with that for now. The device must be attached to a PCI bus and needs two additional values (well, corresponding memory-backend-file needs them): size and path. Despite using memory-backend-file this does NOT add any additional RAM to the guest and thus I've decided to expose it as another device type instead of memory model.
