QEMU is a generic and open source machine emulator and virtualizer
QEMU can use other hypervisors like Xen or KVM to use CPU extensions (HVM) for virtualization
the target architecture matches the host CPU, this mode may still benefit from a significant speedup by using a hypervisor like KVM or Xen
When running QEMU in headless mode, it starts a local VNC server on port 5900 per default. You can use TigerVNC to connect to the guest OS: vncviewer :5900
