Iv just got myself a nice dual core 4 GB RAM laptop, and i`m like to start playing round with different servers and stuff in a virtual environment using the laptop. Is it possible to create that kind of thing in vmware player or ms virtual PC or is there any other freeware solution, my laptop is windows 7 which I cant really change.

It is quite possible indeed. Just create the virtual machines and set them up on the same virtual network; it will be as though they are all on the same virtual switch.

If you set all the VMs to "host-only" network, they will only be able to communicate with each other and with the laptop (they won't have direct connectivity to the outside world).

If you need external connectivity, you can set the VMs to a NAT network, which means the laptop will function as a NAT router (using the VMWare NAT service), giving them access to the outside. Alternatively, you can keep the host-only network and configure your laptop to act as a router; that would give you more control over what can go where.

You can achieve all this using VMWare, or its free (and open source) competitor VirtualBox. You can most likely do it in MS Virtual PC too, but I don't really use that.

I dont think virtualbox is Win7 compatible unless someone can tell me otherwise.

also which VMware should I go for Server or workstation, I cant find much on the website about the networking side of things.

Virtualbox is Windows 7 compatible, I have it on both of my 7 machines. VMWare is nice, but not free. I have used trial versions of it and Virtualbox is just as good. I have version 3.2.12 on my desktop and 4.0.* on my laptop. No problems with either.
I have also used PFSense (open source also) in a VM as a GUI to control the network.

Thanx Guys,

DHay13, I have looked on the FPsense site and its a router/firewall although you already knew that.

How do you use FPsense to control the network, it reads as though all it does is route and firewalls.

I honestly don't recall the details. We used it about a year ago in a class I was taking. We only used it as an interface to the routers and switches. I'm not sure what else it is capable of. It worked very well for what we did.

After thinking about it you might be right. We might have only used it for firewall control. I don't even have the setup configured any more.

I would go for VirtualBox but I wonder how productive you can be with a laptop of limited storage space!
