I use an Asus motherboard that supports Vt-d and vt-x. The key thing here is to use vt-d support and was really tricky to find a board with this plus enough pci, supported networking and supported by VMware!. I also then carefully matched the processor to ensure it had vt-d support (they dont all have it). Checking intels website against processor models yeilded that information. <br>
<br>So in the end I went for a Pentium 4 core 2 duo (E8400 3.00ghz). Memory was normal branded but I made sure to have 6 gig of the stuff. I purchased a secondary 1gb network card which was pci xpress and used in the graphic card slot since there was no other available. I have two pci hauppauge cards which use 2/3 of the pci slots. I also have a standard sata hdd which was also supported.<br>
<br>I made sure VT-D was enabled in the bios. The OS installed was vmware esxi 4.1.0 build 260247 (free hypervisor). <br><br>I then installed opensuse 11.4 as a guest os on esx. In the configuration for the guest vm I used PCI Passthrough. Now the really important thing here is, esx will only allow 2 pci devices to be passed through to the guest. Each hauppauge card is registered as 3 pci devices, so 2 cards would be seen as 6 individual pci devices!!!!! However, a bit of trial and error highlighted the fact that you only need to pass through one device for each card, in my case this was the second pci device for each card. Once this was sorted I essentially have a virtual replica of a real box YAY.<br>
<br>In opensuse I can install mythtv, add the tv cards, scan for channels etc. Forget watching tv in a vm as the display adaptor isnt up to it, however so long as the front end works it doesnt matter. You can now connect your front end to the server (providing you set the firewall rules correctly).<br>
<br>In addition I mentioned I setup an iscsi device in vmware using the second network card as a dedicated connection through to my QNap storage device. This allows the traffic to be isolated to the storage and doesnt affect normal LAN traffic. It also allowed me to dynammically provision the size of tv storage.<br>
<br>So how does it perform. My virtual server has run like a dream on 512mb of virtual mem. I have a fedora 14 front end connecting to the server. I have a 54g wireless laptop also running. The only place I have noticed any kind of problem, is believe it or not mythweb. I have over 800 movies and it takes forever to load the thumbnails in on the webpage. TV viewing is faultless around my house, I have had multiple recordings going and watching tv. It doesnt fail, and Ive done several inplace upgrades from various releases of opensuse, so never lost any recordings now!<br>
<br>The best part is my server also runs, Splunk for logging, zoneminder for camera capture, Asterisk for voip calling and ossim for security testing. Its the best setup in my mind as it has totally flexibility.<br><br>Sorry Ive not listed all the hardware, if you drop me an email direct I can answer any more questions or propvide a shopping list or guide etc on the setup :-)<br>

<br>
would you be so kind to share some more details of how you have set this<br>
up, what hardware do you use? ESXI 4.x ?<br>
The new server I have is a Q57-chipset which provides AMT 6.0 with<br>
KVM/VNC which is nice but AFAIK is not fully supported by vSphere.<br>
<br>
Do you use VT-d? any issues or other notable things?<br>
Passthough of the USB-devices or the PCI-card/bus?<br>
<br>
Thanks<br>
