Hi All,

I did began a very big project, I've started upgrade a cluster from 3.5 to 4.3...

It was a mistake:(

Since upgrade, I can't start the host. The UI seems to working fine.

[root@virt ~]# service vdsm-network start

Redirecting to /bin/systemctl start vdsm-network.service

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

[root@virt ~]# service vdsm-network status

Redirecting to /bin/systemctl status vdsm-network.service

Also, I upgraded to until 4.0 , but it seems to same. I cant reinstall, and reactivate the host.

Originally it was an AIO installation.

Please help me solve this problem.

Thanks in advance,
