[ovirt-users] Re: oVirt 4.4.1 HCI single server deployment failed nested-kvm

Hi, This is not my first time, I have installed ovirt, ovirt-hci, rhv and rhv-hci on top of a kvm host many times to test some functionality or to test a new version til this latest version of ovirt 4.4.1 On my first test there was a problem with HCI deployment the gluster part. Now that part works with the new ovirt-node version but not the vm manager deployment part. Regards.
