  3. The boot ISO. Set -cdrom isofile to define the CD-ROM or DVD image file.
  4. Memory.
  5. Boot order.

Is QEMU easy to use?

QEMU is a fast processor emulator using dynamic translation to achieve good emulation speed. It is a free open-source alternative to VMware. As QEMU requires no host kernel patches to run, it is very safe and easy to use.

Does QEMU work on Linux?
