Migrate RHEV guest from command line

Hi ,

1. Can  you advise if there is an option to run    guest  migration  task  from command line ?

2. Also , when  terminated specific  guest  process on a  Host server by default this guest is being restarted on the same host .How to make it will  reboot on alternate  host  ?

3. RHEV  manager host  looks as single  point of failure if not  taking care about its backup  and  possible hardware redundancy  solutions .

Apart of  backup tasks  using  pg _dump  ,  what is the best  practice to have RHEV Manager available as much as possible
