So one day you start you VM and this error came out:
Failed to mount folders in Linux guest. This is usually because
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:
mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3` vagrant /vagrant
mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant` vagrant /vagrant
The error output from the last command was:
/sbin/mount.vboxsf: mounting failed with the error: No such device
😭 😭 😭 😭 😭
So what is happening under the hood is your VM might did update (yum update) and things change, VirtualBox GuestAddition broken.
First of all let's update our kernel file.
❯ sudo yum install kernel-devel && sudo yum install gcc make
After new packages are installed:
❯ vagrant plugin install vagrant-vbguest
Installing the 'vagrant-vbguest' plugin. This can take a few minutes...
You might see error like
An error occurred during installation of VirtualBox Guest Additions 4.3.14. Some functionality may not work as intended.
In most cases it is OK that the "Window System drivers" installation failed.
But that is ok. After that
❯ vagrant vbguest --status
GuestAdditions 4.3.14 running --- OK.
Seems like our GuestAdditions is fixed. Ok let's reload
vagrant reload
Wohooo ~~~
