    ok..

    But how does that effect the host OS? Do the NICs have to be accessible on the host level as well?

    Right now I'm looking at using my existing Server 2003 as the host OS in the interim but I'm aware that putting multiple NICs on it would create problems with multi-honing.. hence the question above.

    If you decide to pay out for something like VMWare ESX Starter then the virtualisation software is best thought of as a virtual network infrastructure that with virtual switches that your virtual machines connect to. The virtual switches connect to your physical switches via any physical NIC's on the host server.

    With this set up you can have a virtual switch that is the DMZ connected with the physical NICs to the out side world. You can then have a second virtual switch with no access to the physical NICs. You can then make a virtual machine as a firewall and connect it to both virtual switches.

    If you stick with the free VMWare Server product then, AFAIK, the NIC'sare always controlled by the host OS. There is no way of assigning a NIC only to be used by a guest OS. With this product this product the guest OS literally shares access to the NIC's with the host.

    Not so, at least with Linux, you can create per VLAN interfaces (see my HOWTO) and assign each logical vlan interface to a guest.

    Re: Starting out with VM: Opinions sought

    how is virtualisation with Server 2003 as the host and Gentoo linux as a virtual machine. Anyone had any problems?

    I am looking to implement at our school. I can decide whether I should use VMware or virtual server 2005. Any ideas would be great.

    thanks

    The bit above is now the big question I'd like answered as obviously I don't want to leave the server wide open to abuse.

    Having looked around it seems that the server would basically be as secure as the least secure OS, in particular the VMWare and host OS which makes sense and I guess leaves me somewhat wary of putting a vmware server on to the net without trying things out a bit first.

    If nothing else I'm thinking that two seperate servers is a good plan.. one in the DMZ with the other in the LAN.
    One nice thing about VMWare security I suppose is that it's 'footprint' is pretty small - which makes me happier than using say Hyper V.
    You can also setup 'virtual' switches on it to seperate you networks (maybe get some more NICS or use VLANS if you have managed switches?).
