Satellite5.7

How reproducible:
Always

Steps to Reproduce:
1. Configure virt-who run at esx mode and send host/guest association to satellite5.7, virt-who send two esx hypervisor to satellite5.7
[root@hp-z220-05 virt-who]#  virt-who --satellite --satellite-server=satellite57jan3.redhat.com --satellite-username=admin --satellite-password=redhat --esx --esx-server=10.73.3.161 --esx-username=Administrator --esx-password=Welcome1! -o -d

2. Go to satellite5.7 webUI, it will show two different hypervisors under "system" tab

"9fea4d56-5ed5-ddfe-b806-e7872726c0d7"

3. Check the profiles under the /var/lib/virt-who
[root@hp-z220-05 virt-who]# ll /var/lib/virt-who/
total 8
-rw-rw-rw-. 1 root root 1678 Jan  4 22:40 hypervisor-systemid-58a14d56-558b-61d0-fbdf-b690cf7255df
-rw-rw-rw-. 1 root root 1678 Jan  4 22:40 hypervisor-systemid-9fea4d56-5ed5-ddfe-b806-e7872726c0d7

4. Delete the profiles under the /var/lib/virt-who
[root@hp-z220-05 virt-who]# rm -rf /var/lib/virt-who/*

5. Rerun virt-who again as step1. check virt-who's log, it has send host/guest mapping info to satellite5.7 successfully.
[root@hp-z220-05 virt-who]#  virt-who --satellite --satellite-server=satellite57jan3.redhat.com --satellite-username=admin --satellite-password=redhat --esx --esx-server=10.73.3.161 --esx-username=Administrator --esx-password=Welcome1! -o -d
