I'm an intermediate Linux user, so this this stuff can be complicated to me sometimes. Right now I'm having trouble setting up a network bridge that virt-manager will recognize. I've arrived at the conclusion that this simply isn't possible on Arch. That said, I can't find any documentation on how to convince qemu to use an existing network bridge. If you're willing, please add this information as well. If you already know how, any pointers would be greatly appreciated.
