Quick Emulator (QEMU) is a generic and open source machine emulator and virtualizer. QEMU itself is launched by entering a simple command of the same name via a character user interface (CUI) in Linux operating system. For example, if the process status (ps) command is entered while a guest system is running, the status of QEMU execution is displayed. The command options “-m 1024” and “-smp 1” indicate the memory capacity and the number of CPUs, respectively, of the guest system. It is not necessarily easy to specify all of these options directly with the QEMU command. For this reason, a graphical user interface (GUI), referred to as “virt-manager,” has been prepared for Red Hat Enterprise Linux (RHEL) as well as for other operating systems to enable the user to operate and manage one or more guest systems.

In the absence of a hardware environment, QEMU simulators can be used to virtualize the hardware environment. QEMU is a virtual machine that supports cross-platform virtualization and can virtualize many hardware environments. RT-Thread provides an ARM vexpress A9 BSP simulated by QEMU. Developers can run RT-Thread based on this BSP. Virtual hardware environments can assist in application development and debugging, reduce development costs, and improve efficiency. To learn how to use QEMU please refer to the appendix “Getting Started with QEMU (Ubuntu).”
A new approach to software vulnerability detection based on CPG analysis
Published in Cogent Engineering, 2023
The main datasets used for experimentation and evaluation are FFmpeg and Qemu (https://ffmpeg.org/download.html). Qemu is a collection of software programs that enable the creation, management, and administration of virtual machines and the operation of virtualized environments on physical servers. The main vulnerability types in this dataset are Dos, buffer overflow error, etc. FFmpeg includes software programs and libraries for processing video, audio, and other multimedia streams. Both datasets are program source codes written in C/C++ language. Table 3 below lists the main components of these two datasets.
