Attaching guy line to loops on tent

I need to fit some guy lines to a tent and am not sure what type of knot to use to secure it.

It needs to be a secure knot under load as well as not working loose when under no load, which seems to rule out the bowline knot. I don't need to remove the guy lines once they're attached.

Would I be best to use a double dragon loop, broach loop, or something else entirely?
