/proc/net/dev no such file or dir

[Hatte John]

 hi:

   I am trying to boot up my linux kerel from virtual machine
,everything goes fine .
   but when I typed 'ifconfig' command , it reports no such file :
/proc/net/dev  .

  What is the reason ? I have enable netcard for my virtual machine
,is this a problem of   software or hardware?

   Is  the file " /proc/net/dev" created at netcard initailize function ?

Thanks!
