Question: I am trying to install virtualbox5.2 on a RHEL 7 VM When I try to rebuild kernels modules I get the following error:

```
[root@myserver~]# /usr/lib/virtualbox/vboxdrv.sh setup
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is currently not set up to build kernel modules.
Please install the Linux kernel "header" files matching the current kernel
for adding new hardware support to the system.
The distribution packages containing the headers are probably:
    kernel-devel kernel-devel-3.10.0-693.11.1.el7.x86_64

```

I tried install kernet-devel and got success message

```
Installed:
  kernel-devel.x86_64 0:3.10.0-693.21.1.el7                                     

Complete!

```

But still the setup fails.

Any idea what is missing here?

Answer: 
First run in terminal: `uname -r` then you will get name and information about current kernel (CURRENT\_KERNEL).

Now you can install with command: `yum install kernel-devel-CURRENT_KERNEL`

Note: replace CURRENT\_KERNEL with string you get from `uname -r`.
`yum install kernel-devel-3.10.0-693.11.1.el7.x86_64` fixed the issue.
