QEMU features and specs

• Open Source
  QEMU is completely open-source, meaning it is free to use and its source code is available for modification and improvement by the community.
• Platform Support
  QEMU supports a wide range of architectures and platforms, allowing users to emulate systems from x86 to ARM and beyond.
• Performance
  When used with KVM (Kernel-based Virtual Machine), QEMU offers near-native performance for virtual machines on x86 hardware.
• Flexibility
  QEMU can be used for a variety of tasks, such as running virtual machines, debugging, or even virtualization for embedded systems.
• Integration
  QEMU integrates well with other systems and tools, making it a versatile component in large, complex setups (e.g., OpenStack).

Possible disadvantages of QEMU

• Complexity
  The vast array of features and configuration options can make QEMU overwhelming and difficult to set up for beginners.
• Performance Overhead
  Without the use of KVM or other hardware acceleration, QEMU's performance can be significantly slower compared to other hypervisors.
• Limited GUI
  QEMU primarily operates via command-line interface, which might not be user-friendly for individuals who prefer graphical user interfaces.
• Sparse Documentation
  While improving, some parts of QEMU's documentation remain sparse or difficult to understand, which can pose challenges during advanced configurations or troubleshooting.
• Resource Intensive
  Running multiple instances of QEMU can be resource-intensive on the host system, which may affect overall performance.
