Why do you want to run it on a VM? I personally wouldnt run it on a VM seeing as they are slower than the host. If you really want it seperate and dont want to pay for it, I would use fedora but if it doesnt matter just put another 2008 server on there to make it easier on you.

We reached the point years and years ago were hardware outpaced the software, and it was beneficial to take a <5% performance hit to run the server in a virtualized environment (and receive a number of benefits). For a simple web server the performance difference will be extremely minimal (only a few percent loss really at the most).

With modern hardware (heck even 3 year old Core 2's) a quad core chip can easily handle a couple of standard VM's. As long as they are mostly idle VM's like FTP, DHCP, AD DC's, web servers etc.. the performance isn't much of an issue.

and on a 'proper' hypervisor like Hyper-V or ESX, for most uses the VM will add less than 5% overhead - it's effectively negligible.

Why not just let 2008 R2 do it?



What my Dad does, he has XenServer running on a bare metal machine. Then he installed a VM of 2008 r2..


But just pick one, server 2003? You don't really need one cause 2008 is already installed and not on a VM. But I suppose you could do a VM of 2008 on Hyper-V, but why? Just to practice with it?

Yes that is correct.

Generally if the VM is primarily CPU intensive then the performance hit will be very minimal (1-2%), if the VM is I/O intensive then you might be looking at a 15-30% performance hit, and it might be best to install the server to a physical box and not virtualize it.

2008 R2 is certainly more secure then 2003, but some consider a linux distro like CentOS to be more secure.

Xenserver is also a "Bare metal hypervisor" like Hyper-V or ESXi, personally I find ESXi to be the preferable option.

There are a number of reasons to run it as a VM, you could consolidate your infrastructure to a couple of boxes and have things like your DC's, file servers, and such as VM's just connected via iSCSI to your storage SAN/NAS without the need to have a server for each, or cramming all services on one box. You could also have your firewall/UTM security appliance be a virtual appliance too to save on hardware/power costs.
