QEMU:
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 10G
(create is to create an image, -f qcow2 sets the format to qcow2, is our final file and 10G is it’s size)
Launching the VM:
qemu-system-x86_64 -enable-kvm -cdrom -boot menu=on -drive file= -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 car
