[vfio-users] [FEEDBACK NEEDED] Rewriting the Arch wiki article

[Garland Key]

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.

Best,
Garland
