'How to set options in qemu

I am following the steps given here. The page asks to set options in qemu for using usbredir.

When I install qemu on fedora there are bunch of qemu related commands like qemu-alpha qemu-ppc qemu-system-mipsel but not a command qemu itself.I do have the Virtual Machine Manager which shows up QEMU/KVM and some xml in the details of the same.

How to configure the options in qemu? I have no previous knowledge of how to configure an option in qemu.
