Well, this idea came to me after I tried to use an OpenGL program that I wrote in Win7 running on KVM with a local SDL display interface. The experience was so bad, and to give it a shot, I ran it on VirtualBox, with the same guest image (but with VirtualBox WDDM drivers) and there was a night and day difference in experience. Also, frankly, IMHO, adding a new card to KVM (regardless of the features it brings to the table) will only provide more choices for the end KVM user!. -Sriram > > -Sriram > > > > ----- Original Message ----- > From: Peter Maydell <peter.mayd...@linaro.org> > To: Sriram Murthy <srira...@yahoo.com> > Cc: Stefan Hajnoczi <stefa...@gmail.com>; qemu list <qemu-devel@nongnu.org>; > "k...@vger.kernel.org" <k...@vger.kernel.org> > Sent: Monday, April 8, 2013 8:11 AM > Subject: Re: [Qemu-devel] Virtualbox svga card in KVM > > On 6 April 2013 00:52, Sriram Murthy <srira...@yahoo.com> wrote: >> (actually, the virtualbox SVGA card is based off of the KVM VGA card) > > Is it possible to implement it as an extension to the VGA > card device, or has it diverged incompatibly such that it > has to be its own separate device model? > > thanks > -- PMM -- SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg
