steps:
1. boot vm with the command:
/usr/libexec/qemu-kvm -drive file=~/share/images/rhel5.4-32,if=virtio,boot=on -no-hpet -rtc-td-hack -smp 2 -m 2G -uuid `uuidgen` -net  nic,model=virtio,macaddr=00:A6:78:FA:DD:55,vlan=0 -net tap,vlan=0,script=/etc/qemu-ifup -cpu qemu64,+sse2 -boot c -vnc :8 -name 5.4-32 -monitor stdio
2. migrate vm with file.
(qemu) migrate "exec:gzip -c > ~/test.gz"
