virtualbox.org

First sorry if my thread is in wrong place
I have VBox running on a Windows Server 2008 Standard host with a Windows Server 2003 guest in it. I would like to give the Guest OS (Win2003) a dedicated IP
I have 3 IPs given by the ISP (provider). How may I use/install one of them into VBox for the Guest OS?

This is needed for me because my software doesn't support multiple cores but i can run it in multiple instances this gives me advantage to use more than one cpu core.

Thank you in advance

Have a look at the networking chapter of the Vbox manual.
You need bridged networking.
Setting the ip address inside the guest works exactly the same as in any other PC.

thanks for the answer i will try
