Dear Klaus, OK, I see -vga vmware, etc. are kvm options. What options do you use? I tried (in K670): $ kvm -m 1024 -cdrom ...KNOPPIX_V6.7.0DVD...iso -vga vmware open /dev/kvm: No such file or directory Could not initialize KVM, will disable KVM support and the resulting emulator is running terribly slowly. Regards, Andrew
