-drive - Advanced configuration of a virtual hard drive:.-hda IMAGE.img - Set a virtual hard drive and use the specified image file for it.For instance: -m 256M ( M stands for Megabyte, G for Gigabyte). -m MEMORY - Specify the amount of memory (default: 128 MB).Use -smp $(nproc) to use all currently available cores. The number can be higher than the available cores on the host system. -smp - Specify the number of cores the guest is permitted to use.-cpu host - (Recommended) Emulate the host processor.To see a list of supported architectures, run: qemu-system-x86_64 -cpu ? -cpu - Specify a processor architecture to emulate.-object rng-random,id=rng0,filename=/dev/urandom -device virtio-rng-pci,rng=rng0 - Pass-through for host random number generator.) and hardware virtualization acceleration -machine type=q35,accel=kvm - Modern chipset (PCIe, AHCI.
Substitute X for the number of the display (0 will then listen on 5900, 1 on 5901, etc).įor example to have QEMU send the display to a GTK window add the following option to the list:
This is probably the option most users are looking for. -display gtk - Display video output in a GTK window.This option is different than the -nographic option. -display none - Do not display video output.-display curses - Displays video output via curses.-display sdl - Display video output via SDL (usually in a separate graphics window).There are a few available options to specify the kind of display to use in QEMU. 8.1 Guest screen resolutions greater than 1920x1024.
