They should not be rebooted automatically, but you might need to do this yourself, see below. > > I have 5 hosts + 1 completely fresh.

What died (storage? hosts? data?), what are you going to restore, how, etc. Which hosts are hosted-engine hosts. Do they have running VMs. We are working on updating the documentation, but it will take some time. For now, you should assume that the safest way is to pass during restore, to engine-backup, '--he-remove-storage-vm' and '--he-remove-hosts'. This will remove from the engine all the hosted-engine hosts and storage. So when you add the hosts back, you'll have to somehow power off the VMs there - the engine will refuse to add them with running VMs. If you do not want to use these options, you should plan carefully and test.
