hi, I''m new to xen, and I use Fed 8 as the host and a Windows as guest, on a intel VT PC, with embedded graphic controller. I''d like to improve graphical perfomances on my windows VM. What is the best way to do so? Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You can also do rootless / seamless Windows virtualisation using remote desktop (see https://help.ubuntu.com/community/SeamlessVirtualization, http://www.cendio.com/seamlessrdp/). Improving the performance of the actual framebuffer device in Xen would require some performance optimisations which I''m not well placed to explain. If you actually want to hack on the code, then you could try asking for hints on the xen-devel list. Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat? And no pedals!

Most network based KVM''s and hardware provided management tools are actually VNC. You do need to be careful about password management and security with it. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

In any case, I guess running VNC within the guest may give better display performance than running it in dom0. Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat?

and what about giving to Windows HVM the entire access to the graphic card. It doesn''t matter if my dom0 is headless, all I want it to do is to emulate the network card. I want dom0 to work as a firewall for domU. 2007/12/9, Mark Williamson <mark.williamson@cl.cam.ac.uk>:> > > > If your Windows supports remote desktops (home Windows generally > doesn''t > > > but the more expensive versions do) then you may find that you can get > > > better graphics performance by connecting to it over the network using > > > rdesktop. > > > > > > You can also do rootless / seamless Windows virtualisation using > remote > > > desktop (see https://help.ubuntu.com/community/SeamlessVirtualization, > > > http://www.cendio.com/seamlessrdp/). > > > > > > Improving the performance of the actual framebuffer device in Xen > would > > > require some performance optimisations which I''m not well placed to > > > explain.
