Q: Create a private network between virtual machines running in multiple hosts using Virtualbox I want to create a private network between virtual machines running in multiple hosts using Virtualbox. Linux will be used as guest operating system, and Windows in the hosts.
How do I set this up using Virtualbox?

A: Option 1: Hardware


*

*Purchase a dedicated NIC for each machine (or use VLANs if your NICs support them).

*Attach these NIC to the virtual machines only

*Connect these NICs together with an isolated physical switch or use VLANs on your switch if it is supported


This should give you a private network between hosts
Option 2: Software


*

*Configure an OpenVPN server on a guest VM

*Have each Linux machine VPN to the OpenVPN server on a network that only exists on the OpenVPN guest VM


By connecting the machines using virtual private networking, you should be able to create a private LAN that only those machines exist on.

A: Logmein Hamachi is a free VPN solution which supports Windows, Linux and OS X. Quite easy to install. It may be a little overpowered for your situation but should work.
Edit: Another, similar option is wippien.com, look at their Mini Wippien option. Quote: Unlike Wippien that combines two worlds together, miniVPN is small appliation that will give you benefit of having VPN without instant messaging capabilities.

A: If the host machines are all on the same network, you may be able to configure DHCP to assign the MAC addresses used by VirtualBox (or VMWare) VMs to a different virtual network.
For example, say all your host machines run on 192.168.0.0.  You could configure DHCP to assign all computers with MAC addresses beginning with 80:00:27 to the 192.168.99.0 network.
Hope this helps.
