Bug 1247928

There is planned change in virt-who that it will only send host/guest association when it's changed (mostly to reduce the load it generates to the candlepin server). Since this issue is not critical, I suggest we wait for this feature as it will also address this bug. Moving to 7.3.

Upstream virt-who (that will get to 7.3 by rebase) is now sending host/guest association only when it changes.

Fixed in virt-who-0.17-1.el7.

Verified it on virt-who-0.17-2.el7.noarch since virt-who can refresh host/guest association every 1 hour. Therefore, verify it.

Verified version:
subscription-manager-1.17.6-1.el7.x86_64
python-rhsm-1.17.2-1.el7.x86_64
python-rhsm-1.17.2-1.el7.x86_64

Verified process:
1. register system to satellite6.2
2. Configure virt-who run at esx mode and refresh interval is 3600s
[root@dell-per920-02 ~]# cat /etc/sysconfig/virt-who  | grep -v ^# | grep -v ^$
VIRTWHO_DEBUG=1
VIRTWHO_INTERVAL=3600

[root@dell-per920-02 ~]# cat /etc/virt-who.d/virt 
[test-esx1]
type=esx
server=10.73.2.95
username=Administrator
password=Welcome1!
owner=ACME_Corporation
env=Library
3. Restart virt-who service and check virt-who's log after 1h.
