Doc Text:	virt-who supports cluster filtering With this update, the virt-who service introduces a filtering mechanism for the Subscription Manager reports. As a result, users can now choose which clusters virt-who should display according to the specified parameters. For example, 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 Rich Jerrido 2015-02-12 21:52:03 UTC

Description of problem:
As a user of virt-who, I would like the ability to limit the virtualization clusters that virt-who queries for host/guest mapping. 

Currently today, in large virtualization environments, virt-who reports all hypervisors to the subscription management system (SAM/Satellite). This becomes very messy in the UI as it shows systems that the end-user does not (and the user does not plan to) have RHEL guests running on. 

This RFE requests the ability to configure virt-who to support a subset of clusters, provided in a list format. 

Version-Release number of selected component (if applicable):
virt-who-0.10-8.el6.noarch

Expected results:

A new option, such as 

VIRTWHO_ESX_CLUSTERS=ClusterA,ClusterB,foo,bar,baz

Is what is desired.

Comment 2 Radek Novacek 2015-02-27 11:15:32 UTC

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

filter_host_parents - if provided, only hosts with parent name (usually ComputeResource) in this list will be reported,
exclude_host_parents - do not report hosts with parent name in this list.

There are also similar options for filtering by host uuids.

Is this acceptable?

Comment 3 Radek Novacek 2015-02-27 19:42:59 UTC

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

Comment 5 Liushihui 2015-04-10 08:02:35 UTC

Verified it on virt-who-0.12-2.el6.noarch, virt-who can filter out specific ComputeResource with "filter_host_parents" and "exclude_host_parents".

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

Verified process:
Precondition:There are two esx hosts under two datacenter in the vcenter.
1.Register system to SAM server
2.Configure virt-who run at esx mode and configure a computerResource which can be filtered.
[root@hp-z220-06 virt-who.d]# cat /etc/virt-who.d/vir 
[test-esx1]
type=esx
server=10.66.79.72
username=Administrator
password=qwer1234P!
owner=ACME_Corporation
env=Library
filter_host_parents="domain-s98"
3.Check the virt-who's log, virt-who can send the specific computerResource to SAM

5. Restart virt-who service can check the virt-who's log, virt-who can send the two specific computerResource to SAM
