virt-who is agent for reporting virtual guest IDs to subscription manager (SAM or Satellite). It works either locally or via remote hypervisor. It obtains list of UUIDs on specified hypervisor (or local system) and then it sends the list of UUIDs (or host/guest association) to the subscription manager (SAM, Satellite). Installation ------------ To just install it use: # make DESTDIR=/usr install You can also create rpm package with: $ make rpm and then install the package Configuration ------------- SAM: It uses rhsm configuration (usually in /etc/rhsm/rhsm.conf). The system needs to be registered in subscription-manager server before running the agent. Satellite: Configuration is stored in virt-who configuration file: /etc/sysconfig/virt-who Usage ----- See the manual page
