Hyper-V or ESXi PCI-E passthrough?

I know, this should be obvious, but i'm just starting to dabble in virtualization and ran into a roadblock and need some advice.

I'm looking at trying to consolidate some boxes into one and virtualize most of it.

Windows home server
Random services OS - torrent, ftp, apache, mediaservers
HTPC

Ideally it would be awesome to be able to put the HTPC on the same hardware as the other two, but I've not been able to verify one way or the other whether or not you can pass through the graphics card to a guest OS. Need the HTPC to be able to directly access the video card for 1080p and audio output over hdmi.

Is the above possible? or is the only solution to run hyper-V in server 2008 R2 and have the HTPC native to that OS so it has direct access and then virtualize the WHS and Services OS?

Thanks for the help, getting excited about taking nerdery to the next level
 
You can passthrough up to two PCI-E devices using VMDirectPath I/O which is a VMware technology enabled by the newest processors from Intel (vt-d) or AMD (IOMMU). So you need to have a RECENT CPU. I think the video card could potentially be passed through that way, but you better make sure you have more than one video card in the server :). Otherwise you'll see the guest OS output on the monitor and you won't have any ability to see your ESXi configuration, etc. You might get some funky-ness in the VM too because of the built in video controller.. you're not going to be able to get rid of that. If it works you'd have to come back here and spill it, because I looked everywhere to see if anyone else tried using VMDirectPath I/O to do what you're doing and found nothing. You've got me really curious. For sure, what you're doing is totally NOT SUPPORTED.
 
You only need a lil atom nettop for the htpc - virtualise the server stuff :)
