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.

Description Kenny Tordeurs 2018-03-16 11:40:29 UTC 
Description of problem:

When a line that is commented out is prefixed with a tab space the line is taken into account by virt-who

# cat esx.conf 
~~~~
[vcenter]
type=esx
server=vmware.sat6.example.redhat.com
username=administrator
password=xxxxx
owner=xxxxx
env=Library
	#filter_hosts=lab-esx-2.example.redhat.com
~~~

Looking at the output we can sse it's using the filter hosts:

# virt-who -od

Key point is that two lines are being treated as one key/value pair.

Dev: let's try to look for instances of the line feed (seen above as %0A), and warn if we detect this is any config values.
