First of all, thanks to Jernej Simon for the response which pointed out my mistake
regards qemu vs qemu-kvm, and the pointer to the correct version. This solved my problem. I have another question regards graphics driver for the Win7 client. I would like to use the VMware SVGA 3D (WDDM) driver on the client, which would give me Windows Aero and potentially better graphics performance, but when I install it in Windows I get the bang symbol in the device manager, and the message that the driver has been turned off. Is this driver supported in QEMU 0.15.1, and if so how do I get it to work? If not, is there some alternative with the capability I mention? Thx, Gus
