Description Liushihui 2016-09-01 05:47:12 UTC

Description of problem:
During the process of registering rhel host to rhevm4.0, virt-who will show "AttributeError: 'NoneType' object has no attribute 'text'" when virt-who run at rhevm mode

Version-Release number of selected component (if applicable):
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

How reproducible:
Always

Steps to Reproduce:
1.Register system to Satellite

2.Configure virt-who run at rhevm mode and restart virt-who service
[root@hp-z220-05 virt-who.d]# vim /etc/sysconfig/virt-who
VIRTWHO_BACKGROUND=1
VIRTWHO_DEBUG=1
[root@hp-z220-05 virt-who.d]# cat rhevm
[test-rhevm1]
type=rhevm
server=https://tyan-gt24-04.rhts.eng.bos.redhat.com:443/ovirt-engine/
username=admin@internal
password=red2015
owner=ACME_Corporation
env=Library

3. In rhevm webUI, add a rhel host to rhevm, check virt-who's log.
[root@hp-z220-05 virt-who.d]# tail -f /var/log/rhsm/rhsm.log

Actual results:
It will show "AttributeError" every interval(60s) until registered to rhevm successfully

Expected results:
It shouldn't show any error info during register rhel hosts.

Comment 1 Chris Snyder 2016-12-22 16:45:44 UTC

The fix here should be to detect when a system is not registered and we are using a rhevm backend and output a better log message saying that the cause of the failure is a lack of registration.

Comment 2 Chris Snyder 2017-05-12 18:21:24 UTC

Where is there a rhevm instance to test against during development?

I would like to request the configuration used for reproduction of this bug.
The config given in comment 0 does not work for me today. (I wonder if the rhevm instance specified exists any longer?)


Thanks for your help!

Comment 3 Liushihui 2017-05-23 03:26:14 UTC

It hasn't reproduced on latest virt-who-0.19-4.el7.noarch. Therefore, close it. Thanks.
