Yep, the ioctl part virtualizes "too much" away, this was fixed in
2.1.1-rc7 IIRC. The relevant patch is here:
http://www.13thfloor.at/~doener/vserver/patches/diff-2.6.16.5-vs2.0.2-rc16-devinet_ioctl.diff
Should apply without any problems.

ifconfig also uses the ioctl interface and thus cannot show the
vserver's ip address either.
