Hey guys,
I'm running the stock plan9 kernel in VirtualBox and I am expecting to see two /dev/etherX entries but there is only one.
When I first installed it it had only one network card present, which worked with no issues. I added a new one (host only network) with the same model (Intel PRO/1000 MT Server) giving me two adapters (the first one is NAT).
However, the /dev/ether0 entry has now changed its Ethernet address and is referring to the 2nd Ethernet card. The first one seems to have vanished. I searched the archives and didn't find anything, however I found one saying to check /dev/kmesg. There seems to be two relevant entries in there which I've put in below.
