Description

On a CloudStack 4.10 setup running with Basic Networking we noticed VMs being in the "Starting" state.

After investigating in the VR we show the "ip rule show" command run for ever and never end. This causes Python scripts to wait and thus never start the Instance.

This seems to be a issue in CsHelper.py where it uses p.wait() which might block in certain situations.
