Hi,
I don't have power management devices on the Intel NUC. You probably missed the message where I posted this because of https://lists.ovirt.org/archives/list/users@ovirt.org/thread/4WRVQKDASO7YORTR24UINCHVGAWWXU4T/.
For production you will need hardware that supports power management (either the servers or external device, like UPS). In case you need just to test ovirt with power management, you can setup software power management on the hypervisor, where the ovirt nodes will be hosted as nested. I had luck with following approach:
Assumption:
Baremetal: the host where nested KVM is setup.
Ovirt VMs: CentOS7-ovirt0, CentOS7-ovirt1
[root@baremetal ~]# yum install python-pip -y
[root@baremetal ~]# yum install -y zeromq-devel
[root@baremetal ~]# yum install -y gcc python-devel libvirt-devel
[root@baremetal ~]# firewall-cmd --permanent --zone=public --add-port=623-624/udp
[root@baremetal ~]# firewall-cmd --reload
[root@baremetal ~]# vbmc add CentOS7-ovirt0 --username root --password yourpass --port 623
[root@baremetal ~]# vbmc add CentOS7-ovirt1 --username root --password yourpass --port 624
[root@baremetal ~]# vbmc list

at node0 host (VM) check:
ipmitool -I lanplus -U root -P yourpass -H <hardware host IP> power status (default port is 623)
ipmitool -I lanplus -U root -P yourpass -H <hardware host IP> power status -p 624
at ovirt GUI you need lanplus=1,-p623 and lanplus=1,-p624 options for each host.
