Answer 1

Downgrade to Virtual Box 5.1.14 from 5.1.16 works fine.

Answer 2

vagrant plugin install vagrant-vbguest

This didn't work for me, it seems to be incompatible with vagrant 1.9.2, I uninstalled the latest version of virtual box (5.1.16) and installed version 5.1.12 with the latest version of vagrant 1.9.2 and homestead and it works for me.

Answer 3

I have similar issue, check header if it's not match then run below command

CentOS: sudo yum update && sudo yum -y install kernel-headers kernel-devel

vagrant reload

it works for me.

Answer 4

I am using Vagrant 1.9.4 and VirtualBox 5.1.20. No solution here helped me.

I finally got around the problem by disabling auto updates for the guest additions:

Vagrant.configure("2") do |config|
    config.vbguest.auto_update = false
    [...]
end

It's more of a hacky workaround than a solution. I still don't really know what the actual issue is, but I assume it is connected to this: https://www.virtualbox.org/ticket/16670

Answer 5

It is bug in Vbox. There is an solution to fix.

Login to Vbox guestos: By default password is (vagrant/vagrant)

su
ln -sf /opt/VBoxGuestAdditions-5.1.20/lib/VBoxGuestAdditions/mount.vboxsf /sbin/mount.vboxsf
mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant

shutdown

run cmd in from local machine cmd prompt:

vagrant up

It will work.
