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 Amar Huchchanavar 2017-05-01 08:57:43 UTC 
Description of problem:
Virt-who could not read the guest-host mappings if 'hypervisor_id=hostname' and 'filter_host_uuids' are present in the configuration file.

'filter_host_uuids' is not compatible with 'hypervisor_id=hostname' option. We need to use 'filter_hosts=' to filter hosts.

Version-Release number of selected component (if applicable):
virt-who-0.17-11.el7_3.noarch

How reproducible:
Always

Steps to Reproduce:
1.Configure virt-who with below settings.
[howst-vcspv01]
type=esx
[all other details]
hypervisor_id=hostname
filter_host_uuids="446e2e7d-825a-5ca0-8cee-13ae9f56c903","4a9d7c0f-7058-4afd-8d06-42661872b48c","118f4087-7535-4187-8bc2-8e07fc676156"
2.Try to report the mappings.#virt-who -o -d


Actual results:
It fails to read the mappings,
~~~
017-04-21 15:07:53,606 [virtwho.main INFO] MainProcess(3074):MainThread @subscriptionmanager.py:hypervisorCheckIn:195 - Sending update in hosts-to-guests mapping for config "vcenter1": 0 hypervisors and 0 guests found
~~~

Expected results:
It should throw syntax error.

If  'hypervisor_id=hostname' option is present in the file, 
then force to use below two options:

filter_hosts="host1.example.com","host2.example.com","host3.example.com"  `OR`
exclude_hosts=host1.example.com,host2.example.com,host3.example.com

[filter_hosts - If provided, only hosts with hostnames in this list will be reported,
exclude_hosts - If provided, do not report hosts with hostnames in this list.]
Comment 2 Kevin Howell 2017-05-04 14:28:29 UTC 
filter_hosts should work with hypervisor_id=hostname.
Comment 3 Kevin Howell 2017-05-04 14:29:11 UTC 
we'll try to address as part of upcoming config linting changes
