[ovirt-users] Overt-Engine Down | Host Unresponsive

Dear Team, I have one question, if Ovirt-engine goes down for some reason. Will it impact my host to go un-responsive and all VMs down? I just faced a situation where my host was in un-responsive status and all VMs were down. I restart the ovirt-engine service and host got activated. Can anyone let me know this situation? Thanks Vijay Sachdeva
