Xen PCI passthrough wiki page created

Xen PCI passthrough wiki page created

[Pasi Kärkkäinen]

Hello,

I've added Xen PCI passthrough wiki page (with help from others):
http://wiki.xensource.com/xenwiki/XenPCIpassthrough

Please verify the content, and add/edit/fix!

btw. Does someone know why Xen wiki doesn't create links to other pages anymore
when I add [SomeOtherPage] to the editor? There are at least a couple of
broken VTdHowTo and XenVGAPassthrough links on that page now..

Hi,

I didnt find any information about that.
Is possible to passthrough a PCI card in a HVM with PV drivers domU without
Intel VT-d ?

Thanks.

Pasi,

MoinMoin doesn't always recognize mixed case words. I changed the
VTdHowTo link to read [:VTdHowTo:] instead, which Moin does recognize.
That is one of a few different ways to link pages -- the other methods
are explained on the HelpOnLinking page.

Unfortunately no.
HVM guest even with PV-on-HVM drivers is still HVM guest and thus required an IOMMU (VT-d).

There's unofficial hack (extra patch) that allows Xen PCI passthrough to *first* started HVM guest,
and only to that guest.. you're on your own with that patch.. it can be found from xen-devel archives.

You can use the AMD IOMMU.
