RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2016:2387 0 normal SHIPPED_LIVE virt-who bug fix and enhancement update 2016-11-03 13:53:39 UTC

Description Liushihui 2016-08-15 08:45:34 UTC 
Description of problem:
When virt-who work at xen mode, virt-who will generate redundant info when no updating info in xenserver.

Version-Release number of selected component (if applicable):
virt-who-0.17-8.el7.noarch
subscription-manager-1.17.10-1.el7.x86_64
python-rhsm-1.17.6-1.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Register system to satellite5.7.
2. Configure virt-who run at xen mode and restart virt-who service.
[root@hp-z220-03 virt-who.d]# cat /etc/virt-who.d/xen 
[test-xen]
type=xen
server=10.73.5.232
username=root
password=Welcome1
owner=ACME_Corporation
env=Library
sat_server=10.73.3.209
sat_username=admin
sat_password=redhat
[root@hp-z220-03 virt-who.d]# cat /etc/sysconfig/virt-who  | grep -v ^# | grep -v ^$
VIRTWHO_DEBUG=1
VIRTWHO_INTERVAL=120
[root@hp-z220-03 virt-who.d]# service virt-who restart

3. Make sure it hasn't any updating in xenserver. After refresh interval(120s), check virt-who's log
[root@hp-z220-03 ~]# tail -f /var/log/rhsm/rhsm.log

Actual results:
Virt-who will generate the same remind info twice when it up to refresh interval.

Expected results:
1. Virt-who should show remind info once.

2. The following info needn't to show when it up to refresh interval.

Additional info:
In rhevm mode, virt-who only show remind info once at the same situation.

Comment 2 Radek Novacek 2016-08-16 16:49:51 UTC 
Fixed in virt-who-0.17-10.el7.
Comment 4 Liushihui 2016-08-31 02:57:10 UTC 
Verified it on virt-who-0.17-10.el7 since virt-who won't generate redundant info in the log. Therefore, verify it.

Verified version:
virt-who-0.17-10.el7.noarch
subscription-manager-1.17.10-1.el7.x86_64
python-rhsm-1.17.6-1.el7.x86_64 

Verified process:
1. Register system to satellite5.7.
2. Configure virt-who run at xen mode and restart virt-who service.
[root@ibm-hs21-12 ~]# cat /etc/virt-who.d/xen 
[test-xen]
