Previously, when there was a failed network configuration, the VDSM would not correctly roll back to the most recent successful configuration. This caused the Red Hat Enterprise Virtualization Manager to lose its connection to the VDSM host. Now, if a network configuration is incorrect, the previous settings will automatically be restored.

vdsm log for the rollback error
Description of problem:
When connectivity check fails after incorrect setupNetwork configuration and the rolling back step in, the host stays in Non responsive state.
The host performs network rollback, the ifcfg-"xxx" shows the correct (rolled back)configuration for the Network, but ifconfig shows incorect (not rolled back)configuration
How reproducible:
always
Steps to Reproduce:
1. Create VM Network and attach it to the host's NIC
2. Change the IP of the Network to the static (in the same subnet as rhevm Manager) and press ok button
3. Wait for about 2 minutes(the rolling back time)
Actual results:
The rollback is executed, but the IP on the interface is not rolled back and as a result there is no connectivity between the manager and the host
Expected results:
The ip on the interface should be the correct (rolled back ip)
