No VirtualBox Guest Additions installation found

[geerlingguy]

Unless using this box with the vagrant-vbguest Vagrant plugin, you won't end up with Guest Additions being found (and even then, it looks like the installation fails. Something may be breaking during the installation.

When I started up box version 1.0.1, I got the following message:

See above issue, upstream. Testing if that's the fix.

[geerlingguy]

I keep getting the same problem, not sure why.

[geerlingguy]

Trying a manual install:

$ vagrant upload /Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso /tmp/VBoxGuestAdditions.iso
$ vagrant ssh

Inside the VM:

$ sudo su
# mkdir /mnt/vbguest
# mount -t iso9660 -o loop /tmp/VBoxGuestAdditions.iso /mnt/vbguest/
# cd /mnt/vbguest
# sh VBoxLinuxAdditions.run
...

Ended up with the same error.

So tried:

# yum install -y elfutils-libelf-devel
# sh VBoxLinuxAdditions.run

And... the install seems to get through the kernel mods, but still errors out at:

ValueError: File context for /opt/VBoxGuestAdditions-6.0.12/other/mount.vboxsf already defined

I'm wondering if the sh context in the Packer build is different than the sh context me in an interactive session? I'm going to debug the packer_rhel role to see if that package is showing up in yum list installed right before attempting the additions installation.

[geerlingguy]

It's definitely there during install:

elfutils-libelf-devel.x86_64                0.174-6.el8                           @BaseOS

[geerlingguy]

Weird. It looks like the install succeeds in the build:

    virtualbox-iso:     stdout_lines:
    virtualbox-iso:     - Verifying archive integrity... All good.
    virtualbox-iso:     - Uncompressing VirtualBox 6.0.12 Guest Additions for Linux........

    virtualbox-iso:     - 'VirtualBox Guest Additions: Building the VirtualBox Guest Additions kernel '
    virtualbox-iso:     - modules.  This may take a while.

    virtualbox-iso:     - 4.18.0-80.7.1.el8_0.x86_64.

Maybe Vagrant's guest additions detection doesn't work with CentOS 8 yet, and I've burned more than half a day on a ghost chase?

[geerlingguy]

Actually, the check for Guest Additions happens inside Vagrant, and vagrant-vbguest just uses that flag to determine whether to install... so maybe it's a Vagrant issue?

[geerlingguy]

Looks like they're not installed:

# lsmod | grep vboxguest
(no output)
# modprobe vboxadd
modprobe: FATAL: Module vboxadd not found in directory /lib/modules/4.18.0-80.7.1.el8_0.x86_64

Checking if /sbin/rcvboxadd quicksetup all might help ... nope.

[geerlingguy]

Going to have to give up on this for now. It seems to install without error, but it ain't working.

[ifurther]

Maybe VirtualBox 6.0.12 fixed this.

[MedUnes]

@ifurther still experiencing the error under VBox 6 (ubuntu 18)

Closing as all development work for my packer boxes is moving into a central repository, see: geerlingguy/packer-boxes#45
