Hello everybody,

i tried to setup OpenNebula in a fully virtual environment, but when i try to enable new Hosts, they end up with an error. In /var/log/one/monitor.log i can see the following:

```auto
Thu Mar 2 15:00:42 2023 [Z0][HMM][D]: Monitoring host 10.0.0.18(11) 
Thu Mar 2 15:00:42 2023 [Z0][MDP][I]: Command execution failed (exit code: 255): mkdir -p /var/tmp/one 
Thu Mar 2 15:00:42 2023 [Z0][MDP][I]: Permission denied, please try again. 
Thu Mar 2 15:00:42 2023 [Z0][MDP][I]: Permission denied, please try again. 
Thu Mar 2 15:00:42 2023 [Z0][MDP][I]: oneadmin@10.0.0.18: Permission denied (publickey,password). 
Thu Mar 2 15:00:42 2023 [Z0][MDP][W]: Start monitor failed for host 11: Could not update remotes

```

Does anybody know how to fix this issue? I would really appreciate any help.

Regards
