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.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
