<p>Good point. I had the devil of a time getting the graphics drivers installed for my high end cards under CentOS non-virtual so I didn't even try doing so under Xen. From my experience I would not recommend it.</p>

motherboard, but I don't do any video editing.<br>
<br>
Modern hardware with virtual support has IOMMU, allowing passthrough<br>
of some peripheral devices to virtual machines with only a negligible<br>
performance hit. IOMMU is called "VT-d" by Intel. AMD was not yet<br>
shipping when I shopped early this year.<br>
<br>
I'm using IOMMU passthrough for other things, but not yet for video.<br>
Here's a snippet from Usenet newsgroup gmane.comp.emulators.xen.user<br>
last week that gives something of the current flavor of video<br>
passthrough with Xen:<br>
<br>
At present, Xen 4.0.1 only supports Intel integrated graphics (IGD)<br>
VGA passthrough. Add-on PCI Express x16 graphics cards are not<br>
supported yet. Patches, which are currently unavailable, have to<br>
be applied to Xen 4.0.1. You may wish to passthrough your onboard<br>
VGA instead of your NVIDIA GeForce GTS display card.<br>
<br>
Hope this helps.<br>
