Hyper-V and Network Cards

I'm starting to play around with Microsoft Hyper-V and before I start my first dummy build, I have a question.

First, I want to install Server 2008R2 HyperV on the system then run SBS2010, Server 2008 R2 and Server 2003 in Client sessions.

Will this work?  And do I need seperate NIC's for each OS?

    That will work fine. You can use just 1 NIC for the host and all VMs, or you can use 1 NIC for host management and 1 more NIC for all of the VMs assuming that everything will be connected to the same switch and IP subnet. If you are going to connect things to different networks, it's easier to use 1 NIC per network.

    OK great.  I'm guessing I'm going to need a 'boatload' of memory to do this?

    Add up the amount of RAM you want each VM o have, add 512 MB forthe host, and then another 24 GB for all of the MVs you haven't planned for, and you should have the total RAM needed.  ;-)

    RAM is fairly cheap these days. SBS 2011 needs 8 GB, wants 10+ GB, and can go to 32 GB. The other two VMs probably need 1+ GB of RAM, depending on what you will use them for. Add it all up and I would start at 24 GB if you can on a single processor host.

    I would use 8 GB DIMMs if possible so that you have free memory slots available to add more RAM. The cost per GB for 8 and 4 GB DIMMs is about the same.
