Updated

What is virt-who?


The virt-who tool is used to collect information about virtual guests for presentation to [Subscription Management](https://access.redhat.com/site/articles/143253).

What does it do?


virt-who is run from a RHEL host, be it a virtual or physical machine. It connects to a hypervisor and asks for information about the virtual machines running there for the purposes of reporting that information to [Subscription Management](https://access.redhat.com/site/articles/143253). The tool supports a number of different methods for interrogating the hypervisor, with the default being libvirt.

  • RHEL KVM
  • RHEV
