I have fresh installed opennebula 6.6.0. I want to create host. but always have the same error after initializing it. Password-less ssh for oneadmin user to host was added.  
monitor.log file shows:  
Sat Sep 23 07:13:37 2023 [Z0][HMM][D]: Monitoring host localhost(4)  
Sat Sep 23 07:13:38 2023 [Z0][MDP][I]: Command execution failed (exit code: 23): exec 2\>/dev/null; rsync -Laz --delete ‘/var/lib/one/remotes’/ ‘localhost’:‘/var/tmp/one’/

That command is failing. Try to run it manually as oneadmin and you’ll see the error. Note that since the target is localhost, you need to make sure oneadmin can access the same host it is running without a password.

Thanks for the help in advance  
I am trying to configure shared storage in opennebula through nfs but when I created nfs server and mounted the storage to it now , my hosts are getting monitoring error regardless of it that passwordless ssh configuration is working fine.
