Steps to Reproduce:
1. Register orig host, guest and dest host to Satellite 
2. On orig host, Migrate guest to dest host
[root@hp-z220-05 rhsm]# virsh migrate --live 7.1_Server_x86_64 qemu+ssh://10.66.144.4/system
root.144.4's password: 
3. On orig host,Start virt-who serice, virt-who's run at libvirt mode and interval is 10s
[root@hp-z220-05 rhsm]# service virt-who restart
Stopping virt-who:                                         [FAILED]
Starting virt-who:                                         [  OK  ]
[root@hp-z220-05 rhsm]# virsh undefine 7.1_Server_x86_64
Domain 7.1_Server_x86_64 has been undefined
4. on dest host, start virt-who service , virt-who with default configure
[root@hp-z220-06 ~]# service virt-who restart
Stopping virt-who:                                         [FAILED]
Starting virt-who:                                         [  OK  ]
[root@hp-z220-06 ~]# service virt-who status
virt-who (pid  15792) is running...
5. On dest host, Check virt-who's log
