I have “Internal networking” functioning with Windows XP SP2 using a Network
Bridge with a static IP of 192.168.0.1.

The only thing that trouble with was getting my host NIC to be in the
Promiscuous mode because it did not automatically do so.

 

This is for Windows, and it worked for me:
<http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q302348&ID=KB;EN-US
;Q302348>
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q302348&ID=KB;EN-US;
Q302348 

I ran the netsh command after setting up the bridge. The steps from that
article are copied below: 

1. At a command prompt, type netsh bridge show adapter. 

2. Locate the identification number of the NIC that is not responding. 

3. If the NIC is not in Compatibility mode, you can change it manually if
you type the following command, where 1 is the number of the NIC that is
displayed in the first step: 

netsh bridge set adapter 1 forcecompatmode=enable 

4. Run the netsh bridge show adapter command again to verify that the
ForceCompatabilityMode?
<http://www.virtualbox.org/wiki/ForceCompatabilityMode>  field for the NIC
is displayed as Enabled. 

 

I have the Network card within the VM set to “Obtain an IP address
automatically”, of course this means that the XP host system has a DHCP
server to provide IP address to the installed VM’s.

 

I have Windows 98, Windows 2000 PRO, Windows Server 2003 and SUSE 10.2
installed as VM’s and I am able to communicate with them all over the
internal network.

 

 

I hope this helps.

Subject: [vbox-users] Internal networking on windows

 

-- repost from forum -- 

Hi,

I'm trying to get "Internal networking" to work between two XP virtual
machines on a same host but had no luck so far.
I'm sure I'm missing something stupid but I just don't see what. Some
insights would be great 

My configuration is 

Host system :
- Windows XP, wireless card, static ip 10.0.0.10, mask 255.255.255.0,
gateway 10.0.0.254

VM1 ("XP1") :
- Windows XP, static ip 192.168.0.1, mask 255.255.255.0, no gateway

VM2 ("XP2") :
- Windows XP, static ip 192.168.0.2, mask 255.255.255.0, no gateway


Following the docs, this is how I tried to set up the internal network
(named "faraday") : 

> VBoxManage modifyvm XP1 -nic1 intnet

> VBoxManage modifyvm XP1 -intnet1 faraday

> VBoxManage modifyvm XP2 -nic1 intnet

> VBoxManage modifyvm XP2 -intnet1 faraday

So the two vms should now be able to ping themselves, right ? At least
that's what I understood. 

The doc makes it clear (at least to me) that VirtualBox takes care of the
wiring between the two vms and that no changes need 
to be appliedto the host network configuration (no extra virtual nic
needed). 
Using the same network id ("faraday") should be enough to make it happen. 

Obviously it doesn't, the vms don't see each other (no ping response). 

What am I missing ?? 

I also tried to use ips from the same subnet as the host (10.0.0.x) for the
vms but didn't get better results. 

Thanks, 

Cedric
