You can technically be fine with just: qemu-system-x86_64 foobar.qcow2 but I always add `-enable-kvm` and use `-monitor stdio` or `-nographic` depending if I want a graphic display from the vm or not. `-nographic` is all I need to give me access to a serial console in the guest (besides configuring the guest kernel with the paramater `console=ttyS0`). I also add `-m` because the default amount of memory is just 128 MiB, which is typically not enough for my use. Sometimes I add network related arguments, but we're going beyond minimal then.
