user1234567 wrote we need to set up a network and assign IP addresses to Host Win 7 and Guest Win XP and Linux as below:
Host Windows 7: 192.168.56.1
Guest Windows XP: 192.168.56.101
Guest Oracle Linux 5: 192.168.56.102
Set the Network Adapter to Bridged in the VM's Settings and then configure the Network Adapter from within the OSes for the Static IP Address, Subnet, Gateway and DNS Servers, etc.
