Version-Release number of selected component (if applicable):
vdsm-4.18.0-16.git51df339.el7.centos.x86_64
4.0.0-0.7.master.el7ev

How reproducible:
Not clear, every second reboot on puma22.scl.lab.tlv.redhat.com HW for example.

Steps to Reproduce:
1. Install host 4.0 in engine 4.0(latest downstream)
2. Reboot server


Actual results:
Failed rollback transaction last known good network
unified restoration failed
vdsmd is nor running and host stays in non-responsive state in the engine

Expected results:
Should work as expected, restore-net should work and vdsmd must run after reboots
