XCI progress in VGA passthrough

XCI progress in VGA passthrough

[Christian Tramnitz]

Is there any place (other than the ML of course) that keeps tracks of 
the progress in passing through VGA cards in XCI?

Would it be hard to get the necessary changes incorporated into 
"vanilla" Xen? I don't really want mess around with the whole XCI build 
environment just to get to VGA passthrough patches.


Thanks,
    Christian

I've been trying to extract the parts relevant to VGA passthrough to Xen
 unstable. See

That doesn't include any of the ioemu or dom0 kernel changes that are
present in XCI. Also the changes required to actually load the BIOS (as
mentioned by Akio Takebe) are missing.

My main question is, why are those fundamental features being developed
in XCI (with its completely different build environment) and not in
parallel to core Xen?

@Keir, now that 3.4 is released couldn't you start a 3.5 branch where
experimental stuff can be merged? A lot of people have been asking for
VGA passthrough but those hurdles make it really hard for interested
folks to give it a try and deliver feedback...



Best regards,
