To set the resolution for QEMU’s x86_64 virtual machine, you can use the -vga and -display options. Here’s an example command:
qemu-system-x86_64 -vga std -display sdl,1920x1080
In this command, we are using the “std” VGA driver and specifying the display using SDL with a resolution of 1920x1080. You can adjust the resolution to your desired value.
Alternatively, you can also specify the resolution directly with the -vga option if your QEMU version supports it:
qemu-system-x86_64 -vga qxl -device qxl-vga,xres=1920,yres=1080
In this case, we are using the “qxl” VGA driver and setting the resolution to 1920x1080 by providing xres and yres parameters.
Remember to adjust these commands based on your specific requirements and environment.
