You mean a Windows VMWare, right? XP?

I have been watching this for some time, as I use an application that crashes for this reason -- unless an Ethernet cable is plugged in, gethostbyname(gethostname()) returns NULL on Wine (which the native Linux version of gethostbyname also does, for that matter). I haven't dug into ws2_32 enough to be able to fix this, but if there is to be a Definitive Fix(TM) for this function, this behavior should probably be looked at.

There is still things missing in our current knowledge, for example we
have a Win 2008 test VM with 2 network adapters and it returns the
default route as second IP instead of first in gethostbyname.
