This feature is quite complex and needs more time to do it for all the backends in virt-who, moving to 7.2.

There is now support for reporting state of guests for all hypervisors in the upstream repository. It will be part of virt-who rebase in RHEL-7.2.

Fixed in virt-who-0.14-1.el7.

verified it on virt-who-0.14-1.el7.noarch since virt-who can report guest's attribute and state on all supported hypervisors. Therefore, verify it.

virt-who-0.14-1.el7.noarch
subscription-manager-1.15.5-1.el7.x86_64
python-rhsm-1.15.3-1.el7.x86_64
