I have now resolved the cause of the lack of NAT Internet connection on 

a Virtual Box MS Win 7 guest.  After I installed SL 7.2 on my wife's new 

laptop,

I restored (via a cp from an external USB hard drive that held all of 

the files that were not SL installed, including all of the Virtual Box 

guest files) the Virtual Box

guest files from her previous laptop to the new machine.  I installed 

the Virtual Box EL7 RPM, configured VirtualBox to recognize the restored 

guest files, and the

NAT network functioned over the 802.11 WNIC controlled by SL 7 Network 

Manager -- everything worked (indeed, any statements that NAT would not 

work with 802.11 in

"new" kernels were indeed red herrings).  When I then restored her guest 

machine (MS Win 7 Pro as well) to my SL 7 laptop, again, NAT worked.  

Thus, I have determined that

(somehow) the MS Win device NIC device driver that Virtual Box uses to 

connect to the NIC supplied by Virtual Box to the MS Win 7 guest was 

"broken".



I have created a second virtual disk and have attached this to the MS 

Win 7 system that "works", and am in the process of doing a MS Win 7 

backup (not a Linux backup) to this additional

virtual disk that the MS Win 7 guest "sees" now as drive E: .  I do not 

know MS Win very well at all, using it as an appliance, and real source 

code and OS architectural details are not readily available (several of 

my students who worked in MS Win "shops" have access to material 

licensed only to such "shops", not to persons such as myself, and even 

these have large limitations according to my students.)



  I know that I may remove said virtual disk from the working MS Win guest

and attach it, via Virtual Box, to the non-working MS Win guest.  I am 

not asking for a response to the SL list, but if anyone on this list 

knows how I can use this "backup" virtual hard drive to restore

just the MS Win systems files (specifically, just this NIC driver and 

whatever associated MS Win 7 systems files it "needs"), I would greatly 

appreciate off-list (via my private email, [log in to unmask]

if possible) as to what to do -- or a URL with the necessary 

instructions.  Any help greatly would be appreciated.



All of the guests in question are MS Win 7 Pro SP 1, and all have the 

necessary MS Win

license.  If at all possible, I do *NOT* want to "smash" the 

applications installed into the MS Win guest when I restore just the MS 

Win OS files.
