[ovirt-users] Unable to Start the Hosted Engine and the WebUI

Hi there, I have tried to restart the Hosted Engine but I cannot ssh/ping the Hosted Engine after the restart. The oVirt webUI was down and I cannot start the VM in both GUI and CLI. I have used command "hosted-engine --console" to start a console but error message "Cannot find character device <null>" was prompted. I also checked the status of the Hosted Engine and the its state was "EngineStarting". However, the Hosted Engine will keep restarting in the same host automatically. Please help 1. Is there any commands that I can use to start the VM inside the Hosted Engine CLI. 2. Does anyone know why my Hosted Engine cannot be started successfully and accessed via CLI. Thank you for your help. KT
