How do I setup virt-who on a Microsoft Hyper-V host?
I am following How to configure virt-who service to use Virtual Data Center subscriptions, I want to apply the same to a Microsoft Hyper-V Hypervisor?

Resolution

Configure virt-who on any Virtual System running on any Hypervisors on the environment.

Note: One Virt-who configuration is sufficient to perform the host-guest mapping for the entire environment.

Configure virt-who (for virt-who version 0.14+): On the RHEL guest, edit the /etc/virt-who.d/ file to identify the location of the Microsoft Management Console(HyperV):

 # vi /etc/virt-who.d/virt-who.conf
 
      [hyperv]
      type=hyperv
      server=hyperv.domain.com
      username=administrator  (Local administrator account and password)
      password=administrator_password
      owner=org ID (From the Command # subscription-manager identity)
      hypervisor_id=hostname

Note: Avoid changing the parameters [hyperv], type=hyperv, and hypervisor_id=hostname, because they are the default values which is to be used.

Do not provide hypervisor details in the template.conf file present in the "/etc/virt-who.d" directory because when the virt-who package is updated, it will clear all the data present in it.

After Configuring start and enable the virt-who service.
```
 # systemctl start virt-who
```
Once done, the Hyper-V hypervisors will be available on the This content is not included.Red Hat Hybrid Cloud Console inventory.

```
Track the subscription usage in This content is not included.Subscription Watch service available in Hybrid Cloud Console.
HyperV uses 5985 and 5986 ports for virt-who configuration.
