Are you sure? Did you check with 'ps', searching qemu processes?

If it's still up, but still using a local IP address, you can find it
by searching the hosted-engine logs for 'local_vm_ip' and login there
from the host.

This probably indicates a problem, but I agree it's not very helpful.

Right - so please search inside it.

Also please check the hosted-engine deploy logs themselves.
