[ovirt-users] oVirt hosted engine install error: Failed to verify Power Management configuration

Hello, i am new to ovirt and i am trying to install it on minimal-install centos 7. i have been able to iron out all the wrinkles to create the host-engine, except for this error: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The host has been set in non_operational status, deployment errors: code 505: Host ovirt.kdsplumbing.com installation failed. Failed to configure management network on the host., code 9000: Failed to verify Power Management configuration for Host ovirt.kdsplumbing.com., fix accordingly and re-deploy."} can someone layout what this issue is all about or point me in the right direction? i have been battling ith this for 2 days now, without any clue on what it is about. thanks
