Hi, I''m tying to configure Xen such that the HVM guests do not see the VGA. I''m setting up HVM guests which will only have interaction with the network and am trying to get rid of any excess functionality and overheads. Ideally, is it possible to configure Xen (or edit Xen code) such that the VGA is not even announced on the virtual PCI bus? Right now it''s announced as 00:02.0 inside the HVM guest (checked using /sbin/lspci command). Maybe you have some tips about Xen configuration or a place in Xen code where such change could be made? I''ve browsed much of xen/arch/x86/hvm/* as well as other directories, but have no luck yet. Thanks in advance for any help, ~ Jakub _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You''d get much less overhead when using PV domUs. If the domU/guest OS is not PV-capable, installing PV drivers should help reduce the emulation overhead.> > Ideally, is it possible to configure Xen (or edit Xen code) such that > the VGA is not even announced on the virtual PCI bus?You could probably try these combination on domU config file: nographic=yes serial=pty -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
