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).

Doc Text:	Filtering for hypervisors reported by virt-who The virt-who service introduces a filtering mechanism for the Subscription Manager reports. As a result, users can now choose which hosts virt-who should display according to the specified parameters. For example, they can filter out hosts that do not run any Red Hat Enterprise Linux guests, or hosts that run guests of a specified version of Red Hat Enterprise Linux.	Story Points:	---

Comment 3 Radek Novacek 2015-02-27 11:08:22 UTC

This feature is now implemented upstream like this: there are two options that affects which hosts are filtered:

filter_host_uuids - if provided, only hosts with uuid in this list will be reported,
exclude_host_uuids - do not report hosts with uuid in this list.

Is this acceptable?

Comment 4 Radek Novacek 2015-02-27 19:42:03 UTC

Fixed by rebase to virt-who-0.12-1.el6.

Comment 7 Stephen Gilson 2015-04-02 16:55:50 UTC

CCS has determined that this bug should be described in the RHEL 6.7 Release Notes. Please update the Doc Text field with a summary feature description.

Comment 8 Liushihui 2015-04-10 06:56:19 UTC

On the virt-who-0.12-2.el6.noarch, virt-who can filter out one host, but it's failed to filter out multi-hosts, Therefore, reopen it.

Checked version:
virt-who-0.12-2.el6.noarch
subscription-manager-1.14.1-1.el6.x86_64

Checked process:
Precondition:There are two esx hosts in this vcenter.
1.Register system to SAM server
2.Configure virt-who run at esx mode and configure a host which can be filtered.
[root@hp-z220-06 virt-who.d]# cat /etc/virt-who.d/vir

owner=ACME_Corporation
env=Library
filter_host_uuids="86b2bd00-8bad-11e2-87f4-6c3be514699d"
3. Restart virt-who service , check the virt-who log, it can filter out ""86b2bd00-8bad-11e2-87f4-6c3be514699d""

4. stop virt-who service, then configure virt-who filter out two esx hosts.

5. Restart virt-who service, check the virt-who's log

2015-04-10 14:50:36,061 [DEBUG]  @subscriptionmanager.py:76 - Authenticating with certificate: /etc/pki/consumer/cert.pem

Result: virt-who skipping two hosts, it send a null host/guest mapping when setting filter out two esx hosts. 

Expected result: virt-who should send the two host/guest's mapping info which specified in the configure file to SAM server

Comment 9 Liushihui 2015-04-10 07:08:41 UTC

If set "exclude_host_uuids="86b2bd00-8bad-11e2-87f4-6c3be514699d,aee4ff00-8c33-11e2-994a-6c3be51d959a"", it will send these two hosts to SAM server.Actually, it shouldn't send these host/guest info to SAM server at this time.
It seems the function of "exclude_host_uuids" and "filter_host_uuids" are totally reverse when there are mult-hosts in the configure file.

Comment 10 Liushihui 2015-04-10 07:45:34 UTC

Please ignore commend 8 and commend 9 which is result in the incorrect config. 

Radek, Could you help me to modify the bug status to ON_QA? I will verify it again, sorry for my mistake, thanks.

Comment 11 Radek Novacek 2015-04-14 05:37:45 UTC

Moving back to ON_QA.

Comment 12 Liushihui 2015-04-14 08:40:39 UTC
