Mouse cursor disappers inside the VirtualBox VM when installing CentOS 7

Tried to create a VM using CentOS 7 ISO on VirtualBox 6. The VM booted fine and showed WELCOME TO CENTOS 7 screen, the issue is that clicking inside the VM would cause the mouse cursor to disapper. The VM is still usable but you have to use the keyboard to navigate the OS. To workaround the issue, shutdown the VM and change the settings System | Pointing Device to USB Tablet.

CentOS 7 networking not working on VirtualBox

It seems like this is by design (for security?) that CentOS 7 does not have networking working by default. Anyway, to fix this on VM running VirtualBox, edit /etc/sysconfig/network-scripts/ifcfg-enp0s3 and change the line that says ONBOOT=no to ONBOOT=yes and then reboot the machine.
