AFAICT, AMD A6-4400M supports hardware virtualization (aka KVM in the Linux world). I'd recommend you to try using qemu-kvm instead of qemy-system-x86. That should improve the performance noticeably. In addition, the SL image you've downloaded is 64 bits. I don't know if you try to run that via qemu-system-i386 or qemu-system-x86_64. The former is 32bit /emulation/, the latter 64bit. But only qemu-kvm uses virtualization. Try also to kick off your images using virt-manager. It's usually fairly simple to configure new VMs that way, and just point it to your images. This way, virt-manager/libvirtd will take care of setting up the proper arguments to qemu-kvm, for better performance. Also try to use the virtio drivers wherever possible, as they don't require the complete hardware emulation layer. -- kind regards, David Sommerseth
