Something's off here:

Using machine: pc-0.14
/home/anthony/build/qemu/x86_64-softmmu/qemu-system-x86_64 -kernel 
bin/vmlinuz-3.0 -initrd .tmp-22118/initramfs-22118.img.gz -append console=ttyS0 
seed=64521 -nographic -enable-kvm -hda .tmp-22118/disk-22118.img -M pc-0.14 
-drive file=.tmp-22118/disk-22118.img,if=virtio,snapshot=on -device 
virtio-balloon-pci -device virtio-serial -net nic,model=virtio -net user 
-pidfile .tmp-22118/pidfile-22118.pid -qmp 
unix:.tmp-22118/qmpsock-22118.sock,server,nowait
qemu-system-x86_64: Invalid parameter 'lost_tick_policy'
