If you are unable to move mouse curser on full screen in your VirtualBox vm, this is the correct article to fix this issue. To fix this issue we need to install  gcc, make, perl, kernel-devel and  elfutils-libelf-devel  packages and after that guest addition has to be installed. I am considering that yum is configured on your system. So lets start with installation of packages. Step1: - Install mentioned packages using dnf/yum [root@localhost ~]# yum install gcc make perl -y [root@localhost ~]# yum install kernel-devel -y [root@localhost ~]# yum install elfutils-libelf-devel -y Step2: -  Insert Guest Additions CD image...

You can fix this issue in two way: - 1. Add " host_key_checking = false " in ansible.cfg( best practice ) [root@ansible ssh]# cat >> /etc/ansible/ansible.cfg host_key_checking = false Let's check if issue has been fixed, If I am getting "ping": "pong" response that mean the issue has been fixed. [root@ansible ssh]# ansible all -m ping 192.168.43.72 | SUCCESS => {     "ansible_facts": {         "discovered_interpreter_python": "/usr/libexec/platform-python"     },     "changed": false,     "ping": &qu
