QEMU: A proper guide!

Denshi decides to make the QEMU guide that everyone else was scared of making. A Proper guide. QEMU: https://www.qemu.org/ Commands in the video: Installation: Arch: sudo pacman -S qemu (optionally "qemu-arch-extra" for more architectures) Debian/Ubuntu: sudo apt install qemu Fedora: sudo dnf install qemu To create a virtual image use: qemu-img create -f qcow2 Image.img 10G (create is to create an image, -f qcow2 sets the format to qcow2, Image.img is our final file and 10G is it's size) Launching the VM: qemu-system-x86_64 -enable-kvm -cdrom OS_ISO.iso -boot menu=on -drive file=Image.img -m 2G (-enable-kvm enables KVM, -cdrom selects an iso to load as a cd, -boot menu=on enables a boot menu, -drive file= selects a file for the drive, -m sets the amount of dedicated RAM) (Remember! Ctrl + Alt + G to exit capture, Ctrl + Alt + F to fullscreen!) That doesn't run so good, what can we do to improve it? Basic performance options -cpu host (sets the CPU to the hosts' CPU) -smp 2 (sets the numbers of cores) Basic Graphics Acceleration the -vga option can be used to specify one of various vga card emulators: "qxl" offers 2D acceleration but requires kernel modules "qxl" and "bochs_drm" to be enabled: -vga qxl "virtio" works much better and supports some 3D emulation: -vga virtio -display sdl,gl=on •Site: https://denshi.org
