Hello all (gordon will like this).<br><br>Seems Xen have finally got pcie pass through working with xen HVM domians in DOMu.<br><br>Unfortunately I don't the require chipset to allow me to test this (it needs intel vt-d )<br>

<br>What this basically means is, you'll be able to run Xen, with either a linux system in Dom0<br>or domU, and windows system in DomU and play direct X games, without rebooting. ;-)<br><br>It's got lots of other uses to, like improving a vm's IO prerformance , heheeheh<br>

<br>I'd say this is a interesting development. It's early days, so I guess it's not too stable.<br>Who can tell.<br><br>So if you have this
chipset, please give it a try...... <br><br>I've also heard some crazy talk about bios vendors building hypervisors into the bios's.<br>So, you can just parition your machine, without the aid additional software.<br>
