Errors with virt-who

Hi,

In the foreman/production.log, there is errors with virt-who config for
VMware ESX :

[foreman-tasks/action] [E] Validation failed: Architecture can't be blank,
Operatingsystem can't be blank (ActiveRecord::RecordInvalid)

[katello/cp_proxy] [E] ForemanTasks::TaskError: Task
a3405662-d7ae-42f2-9074-b3d74414b61a: ActiveRecord::RecordInvalid:
Validation failed: Architecture can't be blank, Operatingsystem can't be
blank

Is it necessary to particular configuration for virt-who or katello ?

Thx.
