[ELDK] RE : RE : How can I build agin the toolchain ? (ELDK)

Hi Detlev and Wolfgang,

--------------------------------------------------------------------------------------------------------------------------------------------
***********************************************SOLUTION N°1**************************************************************************
--------------------------------------------------------------------------------------------------------------------------------------------

I followed the steps on this link http://www.denx.de/wiki/DULG/AN2009_02_EldkReleaseBuildEnvironment with QEMU.
when launching QEMU as told in the link :

# qemu -m 1024 -net nic,model=rtl8139 -net tap,script=/etc/ifup-build -hda root-rh-7.3.img -hdc /dev/vg0/eldk_build

I got these errors :
/etc/ifup-build: could not launch network script
Could not initialize device 'tap'

The ifup-build file exists and I have not done modifications in it. Concerning the device tap : I tried before launching QEMU :
# tunctl -d tap0
Set 'tap0' nonpersistent
# tunctl -u alberix -t tap0
Set 'tap0' persistent and owned by uid 1000

and then :
qemu -m 1024 -net nic,model=rtl8139 -net tap,fd=tap0,script=/etc/ifup-build -hda root-rh-7.3.img -hdc /dev/vg0/eldk_build

The next steps worked pretty well (I have done exactly what it's told in the link above) till I tried to access the VBH from the host with this command line as explain on the link : 
$ cd /net/eldk-build/opt/eldk/
It says No such file or directory
On my envirronment host, I use Ubuntu : there is not directory /net so it's normal. How can I reach /opt/ ? Is there any command to do from the host to make him being able to see /opt/ ? (When I look for /opt/, it doesn't fing anything)

I  thought it may comes from tap0.
after this command line :
ifconfig tap0 10.100.0.1 netmask 255.255.255.252

I have this network configuration on the host :

And this network configuration on the VBH :

I should be able to ping the VBH from the host (the same in the inverse way) but I don't. 
PING 10.100.0.2 (10.100.0.2) 56(84) bytes of data.
