Can i run a virtual server on my server and use the other network ports, or does that require black magic?

I have one big ol' server with quad core processor, RAID 5 and all that which makes it a powerfull (enough) server.

I now need to run 'Untangle' which is a linux based gateway software that basically needs its own machine to do what it does.

here's my thinking:

I only use 1 of the 4 network connections on my server, and have plenty of capacity to use.
Could I install 'Untangle' on a virtual machine on my server, and tell it to use two of the network ports without screwing up anything on the server (which acts DC, DNS, DHCP and file server).

Is it possible?
Would one of the free virtual machine softwares do the trick?

you may be able to use an run Oracle Virtualbox 4.0, and create your Linux VM.

as long as each of the virtual machines bind to a separate physical network card , you should corss any problems

Correction "you shouldn't corss any problems"
Depending on your hardware and OS will depend on what you can do.

You say you have a 'big ole server' - what sort of 'big ole server' as it may not support virtualisation (it needs either Intel VTx or AMD-V built into the BIOS and a supporting CPU).  Make and model would help here :)

Also, what version of 2008 you are running can have a bearing on how to virtualise - you could run HYPER-V which is Microsofts offereing and it works very well and effectively.  Alternatively, you can use Virtualbox, VMware Server, VMware Workstation etc.

I know, but it feels like it's either that or buy another $4,000 server Ii work in an extremely expensive and hard-to-find-hardware kind of place) that does something that requires the same amount of power an intel atom could do. It just feels like it shouldn't have an impact. They have been touting Virtual COmputing for years now, just kind of felt that the worst that could happen is that it does not work an dthen i uninstall it?


@35777692
Yeah, I may...


@35777702
And which VM software would you recommend to do just that very thing? Do you have experience in doing this and can hand-on-your-heart say that doing what you suggest would not impact the DNS, DHCP or any of the other duties of the server?

hi,
your server supports virtualization. (specs here http://www.dell.com/downloads/global/products/pedge/en/server-poweredge-t610-specs-en.pdf)
i run my dc, dhcp and dns on a virtual environment. separate nics for VMs will ensure that no issues srop up, but that again depends on number of users. with around 150 users, i run all VMs with a single nic, and i've never had problems (running over a year now)
i suggest vmware esxi over hyper-v (both free versions) anyday because of better memory management by esxi. i daresay you will be able to run an extra VM on esxi without letting go of performance compared to hyper-v. i am sure others will agree.

You can install the Hyper-V role and then create your VM under Hyper-V. When you create the two virtual networks, they need to be external and attached to your unused NICs. After you create the virtual networks unbind everything from the NICs used for the virtual networks except for the virtual switch protocol. As long as you don't attach the currently in-use NIC to a virtual network your current DHCP won't be affected. Installing Hyper-V requires a reboot, and there are a significant number of hotfixes that you need to request from Microsoft. They are not available via Windows Update. A Google search for "Hyper-v hotfixes" will return a TechNet page with all of the hotfixes.  

I run Hyper-V on several domain controllers. It isn't a problem at all if you don't share NICs like in your case. If you do share NICs there can be a minor issue with DHCP services.
We have a DC running HyperV, DNS And DHCP with no problems at all

HyperV is worth a look, but download, read and understand this first or there may be consequences

which one of the VM software do you gentlemen suggest for running a linux distro?

I read that Hyper V seems not to love Lunux, so I am a bit worried...
If you can run ClearOS as your Linux distro, Hyper-V loves it (as much as an MS product can love Linux)

You could use Hyper-V, VMware Player, VMware Workstation, but as am VMware fan, I'm going to recommend Oracle Virtualbox.

I don;t really get a choice of distro. It is the one that comes with untangle (www.untangle.com)

I'll try the oracle virtualbox then, thanks...

I recommend Oracle Virtualbox 4.0, which you are going to use, and I get no points. No other poster recommended this.
