Hi Everyone I''m very interested at Xen and i want to use it on a new Intel core2 computer with VT-x support ( which I hope will be under my hands soon ). I want to install both Linux and Windows XP using Xen. I was wonder if: First, Is it matter what are the kernel parameters of the Linux OS ( dom0 ). I mean do I need to tune the kernel for best performance ? ( like /proc/sys/kernel/shmmax ). Second, what kind of drivers will the XP require. the hardware drivers or something else. I''m asking this because beside coding I also love to play demanding 3D games. and I wondered is it possible to install NVIDIA / ATI drivers on a virtualized XP.

If you want the longer answer, please look for "3D Graphics" in the archives of this mailing list, as I''ve written the answer at least 6 times by now... -- Mats> > > Thanks > > > -- > > -------------------------------------------------- > Michael Ben-Nes - Internet Consultant and Director. > http://www.epoch.co.il - weaving the Net. > Cellular: 054-4848113 > -------------------------------------------------- > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Mats,> If you want the longer answer, please look for "3D Graphics" in the > archives of this mailing list, as I''ve written the answer at least 6 > times by now...I read your new FAQ item. Now i think about the use of two graphics cards. Most of the new boards come with two PCI-E Slots. Card 1 Memory Area 0 - 256M Card 2 Memory Area 256 - 512M The main Dom0 use only the memory area from 0 - 256MB. The DomU use the memory area above the 256MB and could access the second graphic card. Under HVM / Windows i disable the second card, and the first under windows one use the memory from the second from the pci. If this possible? Today two cards are cheap. Maybe we could simple patch the main System to reroute the access?

What you describe is an IOMMU implementation, where the address generated by the card is translated to another physical address. But we have yet to see (desktop) machines with IOMMU implemented in them.> > If this possible? Today two cards are cheap.
