Description of problem:
If delete hypervisor on Satellite webUI, then virt-who send this hypervisor to satellite again, it can't show on WebUI.

Version-Release number of selected component (if applicable):
virt-who-0.20.2-1.el7sat.noarch
subscription-manager-1.17.15-1.el7.x86_64
python-rhsm-1.17.10-1.el7_3.x86_64

How reproducible:
50%

Steps to Reproduce:
1.Register system to satellite, make virt-who run at esx mode,then restart virt-who ,virt-who send two esx hypervisors("bootp-73-131-104.rhts.eng.pek2.redhat.com" and "bootp-73-131-168.rhts.eng.pek2.redhat.com") to satellite
[root@esx-rhel7 virt-who.d]# cat /etc/sysconfig/virt-who  | grep -v ^# | grep -v ^$
VIRTWHO_DEBUG=1
VIRTWHO_ESX=1
VIRTWHO_ESX_OWNER=Default_Organization
VIRTWHO_ESX_ENV=Default_Organization
VIRTWHO_ESX_SERVER=10.73.131.114
VIRTWHO_ESX_USERNAME=administrator
VIRTWHO_ESX_PASSWORD=Welcome1!
[root@esx-rhel7 virt-who.d]# service virt-who restart

2. In satellite webUI, delete one esx hypervisor1(bootp-73-131-104.rhts.eng.pek2.redhat.com)

3. Disable esx mode in /etc/sysconfig/virt-who, make virt-who run at fake mode which has the same data as previous esx mode. virt-who can send fake mapping info(two esx hypervisors as previous) to satellite.

4. In satellite webUI, go to hosts--> Content hosts, check the esx hypervisor1(bootp-73-131-104.rhts.eng.pek2.redhat.com) which deleted in step2 

Actual results:
Although virt-who has send the esx hypervisors to server, it still can't show on satellite webUI.

Expected results:
The deleted esx hypervisor should show on webUI again since virt-who has send it to server.

Additional info:
If it can't reproduce after step4, please delete the esx hypervisor again on satellite webUI, then restart virt-who, it should reproduce.
If it still can't reproduce, do the same test once again, it should reproduce.
