Hello,

I am trying to install and configure vdsm in a newly created centos 7.3.The packages that I have installed is vdsm, vdsm-cli and libvirtd.

Now when I am trying to start the vdsm service I am getting this error.

[root@localhost ~]# systemctl start vdsmd

Job for vdsmd.service failed because the control process exited with error code. See "systemctl status vdsmd.service" and "journalctl -xe" for details.
