Mouse integration not working in Guest OS which is Centos 7.

My Host OS is Window 7.

I have installed guest additions and also I ticked sharing bidirectional.

  • Looks like your guest is CentOS Minimal. Suspect you cannot have mouse integration if your guest has no GUI – fpmurphy Dec 8 '16 at 15:47
  • The problem is not at the guest side. It's VirtualBox that's refusing to attach the iso to the guest. – Johnson Steward Dec 8 '16 at 17:14

Right-click the VM from the list, click Settings, click System on the left menu, and change Pointing Device to "USB Tablet" instead of "PS/2 Mouse".

Try, this in Guest. eject /dev/sr0 no errors? As root or with sudo mkdir /media/cdrom with extended rights too mount /dev/sr0 /media/cdrom

`yum install dkms kernel-devel` 

yum groupinstall "Development Tools" if not installt.
