Introspection of QEMU emulator peripherals configuration

Abstract
QEMU is a widely used and fairly accurate emulator capable of emulating dozens of guest systems. Emulation of the system involves the configuration of virtual devices, which are supported in large numbers in QEMU, which entails a very long and complicated command line to start the emulator. When using deterministic replay, the situation is complicated not only by additional and not quite obvious parameters, but also by the need to synchronize recording and retrace launch command lines. Machines can have a different set of devices depending on the platform and even the version of the emulator. The article describes obtaining information about the devices of the QEMU emulator through the QEMU Machine Protocol for using this data in a graphical interface. The QemuGUI graphical interface supports the full cycle of work with the emulator: creating and configuring a virtual machine, starting in normal mode and in deterministic replay mode, interacting with the machine through a QEMU monitor.
