If I start kvm-qemu with no CPU option everythign works and hte guest machine detects cpu as QEMU Virtual CPU version 0.9.1 iv I run qemu-kvm -cpu core2duo the guest hangs at boot time when it detects the CPU. I do not know how to fix it. I also do not know if using -cpu swtch can improve performances. thank you Rick
