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:	---

Description jalviso 2014-11-13 05:36:58 UTC

Description of problem:

virt-who is mapping all the host in Vmware Vcenter.

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

virt-who (all versions including latest)

How reproducible:

Steps to Reproduce:

1. Configure and run virt-who service of 1 of the virtual guest running on one of the Vmware host
2. All host in Vcenter are mapped to the Customer Portal
3. Customer apply Virtual Datacenter physical subscription to the host.

Actual results:

All host are mapped to the Customer Portal

Expected results:

Only required host will be mapped to the Customer Portal. 

Additional info:

If unwanted hosts are deleted, during the next run of virt-who, all the hosts will be mapped again (including the deleted ones). Cannot used one_shot in virt-who configuration as DRS Disaster Recovery System is implemented on the Vcenter.

Comment 3 Radek Novacek 2014-11-26 13:59:52 UTC

I'm not sure I understand proposed idea.

Customer wants some kind of blacklisting/whitelisting of which hosts will be reported to the SAM?

So lets say we have following "full" mapping that we can get from virt-who now:

{
    'host-1-uuid': [
        'guest-1-on-host-1-uuid',
        'guest-2-on-host-1-uuid'
    ],
    'host-2-uuid': [
        'guest-1-on-host-2-uuid',
        'guest-2-on-host-2-uuid'
    ]
}

And the customer wants to specify something like this in the configuration file for the given hypervisor:

report_hosts_only = ['host-2-uuid']

And then virt-who will then report this:

{
    'host-2-uuid': [
        'guest-1-on-host-2-uuid',
        'guest-2-on-host-2-uuid'
    ]
}

Is this what customer wants, do I understand it correctly?

Comment 5 Radek Novacek 2014-11-27 12:53:47 UTC

Ok, thanks for confirmation. Marking this bug as RFE for next release.

Comment 12 Radek Novacek 2015-05-07 09:22:18 UTC

This feature has been implemented upstream and will be fixed by virt-who rebase (bug #1200374).

Comment 13 Radek Novacek 2015-06-23 13:32:17 UTC

Fixed in virt-who-0.14-1.el7.

Comment 15 Liushihui 2015-07-16 07:26:25 UTC

Verify it on virt-who-0.14-1.el7.noarch since virt-who can filter out any host which configured in /etc/virt-who.d/XXX

Verified version:
virt-who-0.14-1.el7.noarch
subscription-manager-1.15.5-1.el7.x86_64
python-rhsm-1.15.3-1.el7.x86_64

Verified process:
Precondition:There are two esx hosts in this vcenter.
1.Register system to Satellite
2.Configure virt-who run at esx mode and configure a host which can be filtered.

Comment 17 Radek Novacek 2015-08-25 11:43:56 UTC

Yes, this can be backported to RHEL-6. Please open a tracking bug for that issue and I'll make sure it'll land in RHEL-6.8.
