[ovirt-users] hosted-engine : how to shutdown hosts?

Hi, just a minor problem I guess: I have a small test environment with 2 hosts and a hosted engine on a separate NFS3 share, all running CentOS7. The VMs are running from an iSCSI storage. When I want to shutdown the environment I: - shutdown VMs - enable global maintenance mode - "shutdown -h now" on the hosted engine vm - "shutdown -h now" on the hosts The problem: instead of shutting down, the hosts perform a reboot after a short while. Is this the expected behaviour or a known bug? How can I cleanly shutdown my OVirt-environment? Thank you, Uwe
