Description of problem: After unregister system, virt-who processes which PPID is not 1 can not be killed until 30s. it also won't show system has been unregistered in the rhsm.log. Version-Release number of selected component (if applicable): virt-who-0.16-1.el6.noarch subscription-manager-1.16.6-1.el6.x86_64 python-rhsm-1.16.4-1.el6.x86_64 How reproducible: 80% Steps to Reproduce: 1. Register system to Satellite6. make virt-who run at kvm mode, refresh interval is default. [root@hp-z220-05 tmp]# subscription-manager register --username=admin --password=admin Registering to: cisco-b200m1-04.rhts.eng.bos.redhat.com:443/rhsm The system has been registered with ID: b9f6ca8a-3ae8-4b66-b293-847e39481ce0 2. Start virt-who service [root@hp-z220-05 tmp]# service virt-who start [root@hp-z220-05 tmp]# ps -ef|grep virt-who root 10795 1 0 14:00 ? 00:00:00 /usr/bin/python /usr/share/virt-who/virtwho.py root 11055 10795 0 14:05 ? 00:00:00 /usr/bin/python /usr/share/virt-who/virtwho.py root 11060 9603 0 14:05 pts/0 00:00:00 grep virt-who 3. Unregister system. then check virt-who processes. [root@hp-z220-05 tmp]# subscription-manager unregister System has been unregistered.

After about 30s, check virt-who processes: [root@hp-z220-05 tmp]# ps -ef|grep virt-who root 10795 1 0 14:00 ? 00:00:00 /usr/bin/python /usr/share/virt-who/virtwho.py root 11062 9603 0 14:06 pts/0 00:00:00 grep virt-who Actual results: It still show two virt-who processes after unregister system.

Reopen it on virt-who-0.16-3.el6.noarch since virt-who dead after unregister system. please see the detail as the following: Checked version: virt-who-0.16-3.el6.noarch subscription-manager-1.16.8-1.el6.x86_64 python-rhsm-1.16.6-1.el6.x86_64 Checked processes: 1.Register system to satellite and run virt-who at libvirt mode.there are 2 virt-who threads.

Verified it on virt-who-0.16-4.el6.noarch since virt-who can work normally and system has been unregistered has shown on rhsm log immediately after unregister system. Therefore, verify it.
