15.6. Booting the Manager Virtual Machine in Rescue Mode

Connect to one of the hosted-engine nodes:

$ ssh root@host_address

Put the self-hosted engine in global maintenance mode:

# hosted-engine --set-maintenance --mode=global

Check if there is already a running instance of the Manager virtual machine:

# hosted-engine --vm-status

If a Manager virtual machine instance is running, connect to its host:

# ssh root@host_address

Shut down the virtual machine:

# hosted-engine --vm-shutdown

# hosted-engine --vm-poweroff

Start the Manager virtual machine in pause mode:

hosted-engine --vm-start-paused

Set a temporary VNC password:

hosted-engine --add-console-password

The command outputs the necessary information you need to log in to the Manger virtual machine with VNC.

Resume the Manager virtual machine with the following command on its host:

# /usr/bin/virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf resume HostedEngine

Disable global maintenance mode

# hosted-engine --set-maintenance --mode=none
