I actually got it to work. The reason behind this is that I did not
configure qemu correctly, and did not also include -enable-kvm in the
command line.

sudo qemu-system-x86_64 -name vm -m 1g -enable-kvm -hda
/home/jinho/virt/vms/vm1.img -device
e1000,netdev=net0,mac=00:0c:29:f0:bc:33 -netdev tap,id=net0 -vnc :1
