Apparently, starting with 10.9 (Mavericks), the built-in Intel e1000 driver (AppleIntel8254XEthernet.kext) no longer works with the default e1000 "flavor" (DEVICE_ID) emulated by QEMU (E1000_DEV_ID_82540EM). It seems to work great with E1000_DEV_ID_82545EM_COPPER, though. E1000_DEV_ID_82545EM_COPPER, however, does not work with Windows (I tried XP and 7). So there isn't currently one e1000 DEVIE_ID that could "rule them all", so to speak... Linux works fine with whatever, but then we already expected that :) So, I think it would be nice to be able to select the specific "flavor" of e1000 at run time, along the lines of what this patch does. Thanks, --Gabriel
