Hi,

Please, ensure that you have not forgot to install zun dashboard to the horizon and enable it accordingly, as it's provided by a separate package that should be installed to the same env where horizon runs.

Please refer zun-ui docs for more details:

After I successfully installed the zun service, I logged in to the dashboard, but I could not see the zun entry

I've rebooted all the machines,but invalid.

thanks you !
