Well, you could try mounting the share using the IP on the ethernet card (e.g. 
the lan IP) of the host.

Not sure. I do know that sometimes using 10.0.2.2 doesn't work but using the 
lan IP does. This is due to what may be a bug in the slirp code where the 
localhost ip (127.0.0.1) is not properly rewritten (into 10.0.2.2), but I'm not 
sure whether or not this is the cause of the issue that you are experiencing.
