Dear Centos-Virt:
This is actually a second request for help on the same issue. I finally got to try what several months ago was replayed to me and no joy was to be had. I am afraid the original thread got stale and also had extra, unnecessary data in it.
Guest=XP Pro, SP2 Host=CentOS5; # uname -r; 2.6.18-8.1.15.el5
VirtualBox-1.5.0_24069_rhel5-2.i586.rpm http://www.virtualbox.org/download/1.5.0/VirtualBox-1.5.0_24069_rhel5-1.i586...
I have two nic: eth0 is the internal network; eth1 connects to a DSL modem.
I also have a fully functioning DHCP server on eth0 (works perfectly with Parallels for Linux).
The directions (from hell): http://www.virtualbox.org/download/UserManual.pdf
I am trying to set up a "host interface" network between my XP guest and my Linux host (eth0).
I do believe I FINALLY have it figured out. I wrote myself the following how to. Please feel free to clean it up and make it into an "Official CentOS 5 How To".
The only problem I have left is that the Guest XP can not browse the Host's Samba server by SMB name (IP works fine)

T's CentOS 5 -- Virtual Box "Host Networking" bridge setup:
Note: a lot of this is taken from (with lots of refinements): http://www.linuxweblog.com/virtualbox-host-networking
iptables: after creating br0 at etho's expense, you have to change all references to "eth0" in your firewall to "br0"
br0: will become the internal interface and have a "Fixed" (static) IP address of 192.168.255.10
Support software (required);
