How to filter hypervisors by their hostnames using virt-who in Red Hat Satellite 6

Environment

• Red Hat Satellite 6.2.x
• Red hat Enterprise Linux 7.x
• Red hat Enterprise Linux 6.x
• virt-who-0.18-3.elx.noarch (or newer virt-who versions)

Issue

• How to filter the hypervisor hosts which are reported by virt-who, by their hostnames?
• How make sure that only the required hosts/hypervisors are reported on satellite 6 using virt-who?

Resolution

• Edit the virt-who configuration file /etc/sysconfig/virt-who and ensure that the below parameter have been enabled:

VIRTWHO_SATELLITE6=1

• For example, for VMware virtualization backend, create a new configuration file for virt-who inside /etc/virt-who.d/.

[root@localhost ~]# vi /etc/virt-who.d/esx.conf
[config]
type=<hypervisor_type>
server=<vcenter/esx host>
username=<vcenter/esx_username>
owner=<org_label>
env=Library
hypervisor_id=hostname
filter_hosts="host1.example.com","host2.example.com","host3.example.com"  `OR`
exclude_hosts=host1.example.com,host2.example.com,host3.example.com

NOTE: The org_label entry in the /etc/virt-who.d/ configuration file is provided by executing the below command on the Satellite 6.

 [root@localhost ~]# hammer organization list

• Identify which organization you want the virtual hosts to be assigned to, and use the matching entry in the LABEL column

NOTE: Use any one from filter_hosts or exclude_hosts
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.

Hypervisor Type:

- The hypervisor type can be libvirt, vdsm, esx, rhevm and hyperv.

Restart virt-who Service:

• Restart the virt-who service after the configuration change.

[root@localhost ~]# service virt-who restart

Note: For additional information regarding the virt-who configuration steps please see Virtual Instances Guide
