主题: [ovirt-users] Failed to execute stage 'Environment setup': Command'/bin/systemctl' failed to execute

Hey,

I'm desperately trying to install oVirt hosted engine on a fresh centos 7 system.
After the following steps:

[root@ Centos7 ~]# yum localinstall -y http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm
[root@ Centos7 ~]# yum install -y ovirt-hosted-engine-setup screen glusterfs-server nfs-utils vdsm-gluster system-storage-manager

[user@Centos7 ~]$ sudo su

[root@WesterOS ~]# screen
>hosted-engine --deploy

I get the following error log:

[ INFO  ] Stage: Initializing

          Continuing will configure this host for serving as hypervisor and create a VM where you have to install oVirt Engine afterwards.

          Are you sure you want to continue? (Yes, No)[Yes]:

I have neither firewalld nor networkmanager running and still get this error after a reboot.
Please help me.
