Global maintenance mode turns off high availability for the hosted engine
vm. You should either cancel global maintenance or start vm manually with
hosted-engine --vm-start

Global maintenance was added to allow manual maintenance of the engine VM,
so in that mode state of the engine VM and engine itself is not managed and
you a free to stop engine or vm or both, do whatever you like and hosted
engine tools will not interfere. Obviously when engine VM just dies while
cluster is in global maintenance (or all nodes reboot, as in your case)
there is no one to restart it :)
