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-2017:0675 0 normal SHIPPED_LIVE virt-who bug fix update 2017-03-21 12:35:57 UTC

Description Liushihui 2016-03-24 06:12:18 UTC 
Description of problem:
When virt-who work at local libvirt mode, although no changes in host/guests , virt-who still send mapping info to server periodically.

Version-Release number of selected component (if applicable):
virt-who-0.16-7.el6
subscription-manager-1.16.8-7.el6.x86_64
python-rhsm-1.16.6-1.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. Register system to satellite, make virt-who run at local libvirt mode and enable debug option
[root@dell-pem600-01 ~]# cat /etc/sysconfig/virt-who  | grep -v ^# | grep -v ^$
VIRTWHO_DEBUG=1
2. restart virt-who service and check rhsm.log.
# /etc/init.d/virt-who restart
# tail -f /var/log/rhsm/rhsm.log
3. Make sure no host/guests changes, wait for over 120s.

Actual results:
Virt-who send host/guest mapping info to server side every refresh interval(60s)

Expected results:
Virt-who should show notice info if no host/guest mapping info change in local libvirt mode. for example:
"No change in report gathered using config: "env/cmdline", report not sent."

Additional info:
Comment 1 Liushihui 2016-03-25 02:03:25 UTC 
It has the same problem when virt-who run at vdsm mode.
