Vagrant was unable to mount VirtualBox shared folders

Question

Current setup: Virtualbox 5.1.20 with Vagrant 1.9.3

Previous working setup: Virtualbox 5.1.18 with Vagrant 1.9

Answer 1

For those who land here with almost the same problem as me, below is the solution

TLDR

• VirtualBox guest fail because of system is currently not set up to build kernel modules
• Solution is uninstall kernel-headers.x86_64 0:3.10.0-862.9.1.el7
• Then install kernel-devel-3.10.0-327.el7.x86_64

Solution

1. vagrant ssh

2. sudo rpm -e kernel-devel-3.10.0-862.9.1.el7.x86_64

3. sudo wget ftp://mirror.switch.ch/pool/4/mirror/scientificlinux/7.0/x86_64/updates/security/kernel-devel-3.10.0-327.el7.x86_64.rpm //download the file

4. sudo rpm -Uvh kernel-devel-3.10.0-327.el7.x86_64.rpm //use the file downloaded on step 3

5. exit

6. vagrant reload

Details: Problem

1. Do vagrant up but fail with similar error except

The error output from the command was:

/sbin/mount.vboxsf: mounting failed with the error: No such device

2. Do further reading of the logs and I notice below key words

Installing Virtualbox Guest Additions 5.2.16 - guest version is 5.1.10

An error occurred during installation of VirtualBox Guest Additions

This system is currently not set up to build kernel modules.

Please install the Linux kernel "header" files matching the current kernel

packages containing the headers are probably: kernel-devel kernel-devel-3.10.0-327.el7.x86_64

3. Read logs further

Package kernel-headers.x86_64 0:3.10.0-862.9.1.el7 will be installed

No package kernel-devel-3.10.0-327.el7.x86_64 available.

4. My guest is I need kernel-devel-3.10.0-327.el7.x86_64 to works

Details: My environment

• bento/centos-7.2
• vagrant version: 2.0.4
• virtual box version: 5.2.16
