It's pretty much a testing tool only, and much > of the point is to have message about it's internal state? I do use it as a development tool. I find it very convenient to always have a bunch of libvirt-managed LXC containers, some running hostapd instances with various access point configurations and some used for NetworkManager development and a mac80211_hwsim radio in each of them. An unfortunate side-effect is that my dmesg becomes next to useless due to the overwhelming amount of mac80211_hwsim logging. > johannes Lubo
