I'm not having much luck. I try creating a f7 and f9 vm. On both installs the installer runs slow. Much slower than equivalent vm in vmware under F7. Also both installs get stuck at prompt to initialize /dev/sda. When you answer 'yes' it takes almost 10 minutes for a prompt to come back and say it had some error and retry,ignore,cancel. I'm wondering if the speed issue is related to this being a quad-core machine? </pre> </blockquote> <pre>It's more likely down to your hardware either not supporting hardware virtualization, or supporting it really badly. Is the kvm-intel or kvm-amd module loaded into the kernel? Did 'dmesg' say anything when it was loaded? What is in /proc/cpuinfo flags?
