Re: [Xen-users] Xen 4.2 Windows 8 Issues

[Shane Johnson <sdj@xxxxxxxxxxxxxxxxxxxxxx>]

John,
Some other things I have thought of while reviewing your problem.  I
don't remember where I read it but I remember reading that someone
couldn't get passthrough working during install and only by waiting
till Windows 7 I believe it was was fully installed then they
installed the driver and then enabled passthrough.  Another thing you
might want to try is reducing the amount of RAM you are throwing at
the DomU to below 4G I think it is.  I know there are some posts on
the forums about people having issues with this and if I remember
right there is a solution for running more memory but I don't know
exactly what it is.
