VM Guest's Shared Folders

Many OS' support this package as pre-installed rather than the VMware Tools or installing the VirtualBox Guest Toolkit.

CentOS VIRTUALBOX

For VirtualBox Guests, they require kernel development and a bunch of other packages.

yum install -y gcc make perl bzip2 tar elfutils-libelf-devel kernel-headers kernel-devel
yum update -y
[reboot]
[select Insert Guest Additions CD Image from Devices menu]
mount /dev/cdrom /mnt
cd /mnt
/mnt/VBoxLinuxAdditions.run install
umount /mnt
mkdir /mnt/<mount-point>
mount -t vboxsf <mount-point> /mnt/<mount-point>

And add the following to /etc/fstab

/<mount-point> /mnt/<mount-point> vboxsf defaults 0 0

[https://www.virtualbox.org/manual/ch04.html#additions-linux]

CentOS and Fedora VMWARE

CentOS 8.1's open-vm-tools does not work. You must remove the package and install VMware tools.

dnf remove -y open-vm-tools open-vm-tools-desktop
dnf install -y tar perl
mkdir /mnt/hgfs

Then install the VMware Tools from the client's GUI, which will make the CD available for mounting.

[configure VM to have shared folder]
yum uninstall open-vm-tools
[select VMware Tools Installation from Virtual Machine menu]
mount /dev/cdrom /mnt
tar -xvzf /mnt/VMwareTools-x.y.z-nnnnnnn.tar.gz -C /tmp
/tmp/vmware-tools-distrib/vmware-install.pl
[do you still want to proceed with this installation? [no] YES]
[take the defaults for the rest of the choices]
[reboot and mount points will appear /mnt/hgfs/<mount-point>]

[https://linuxconfig.org/how-to-install-vmware-tools-on-rhel-8-centos-8]

In RockyLinux 9.2, you must install open-vm-tools

sudo dnf install -y open-vm-tools

In CentOS 7.x and 8.2's minimal install, open-vm-tools is already installed and just needs to be started. This also works for Fedora 33.

mkdir /mnt/hgfs
systemctl restart vmtoolsd

[https://www.virtualbox.org/manual/ch02.html#externalkernelmodules]

To mount all the shared folders configured with the VM, type the following as root:

mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other

To ensure the /mnt/hgfs mount points at boot, insert the following into /etc/fstab:

.host:/<mount-point> /mnt/hgfs fuse.vmhgfs-fuse allow_other,defaults 0 0

[https://unix.stackexchange.com/questions/310458/vmhgfs-fuse-permission-denied-issue]

Debian VIRTUALBOX

As root (sudo isn't installed on Debian 9 by default), install the following:

sed -i "s/^deb cdrom/#deb cdrom/" /etc/apt/sources.list
apt-get update -y
apt-get install -y sudo gcc make perl bzip2 tar build-essential dkms linux-headers-$(uname -r)
[reboot]
[select Insert Guest Additions CD Image from Devices menu]
mount /dev/cdrom /mnt
/mnt/VBoxLinuxAdditions.run install
umount /mnt
[reboot]
mount -t vboxsf <mount-point> /mnt/<mount-point>

And add the following to /etc/fstab

/<mount-point> /mnt/<mount-point> vboxsf defaults 0 0

[https://linuxize.com/post/how-to-install-virtualbox-guest-additions-on-debian-10/]

Debian VMWARE

As root with su (sudo isn't installed on Debian by default), install the following:

sed -i "s/^deb cdrom/#deb cdrom/" /etc/apt/sources.list
apt-get install -y sudo make git perl bzip2 tar open-vm-tools

On Debian 9, this will automatically start the open-vm-tools service on the host. /mnt/hgfs will contain all the mount point defined in the Guest's configuration.

On Debian 10, you have to create the mount point and restart the service,

mkdir /mnt/hgfs
systemctl restart open-vm-tools
mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other
echo ".host:/ /mnt/hgfs fuse.vmhgfs-fuse defaults,allow_other 0 0" >> /etc/fstab

Debian 10's VMware Guest works best with 2 cores and 4096MB of memory. It als doesn't allow for setting static IP address through standard boot off of ISO. So do the following:

• modify /etc/network/interfaces to have the following:

allow-hotplug ens33
#iface ens33 inet dhcp
iface ens33 inet static
  address 192.168.x.xxx
  netmask 255.255.255.0
  gateway 192.168.x.xxx
  dns-nameservers 8.8.8.8 8.8.4.4

• modify /etc/resolve.config and reboot

domain local.net
search local.net
nameserver 8.8.8.8
nameserver 8.8.4.4

Ubuntu VIRTUALBOX

For Ubuntu 16.04 and 14.04, install a minimal system using the entire disk with the LVM. If you upgrade the OS, the upgrade scripts make changes to the volume groups and will fail if you don't use the volume manager.

This procedure has been tested with Ubuntu 14.04, 16.04, 18.04, and 20.04

[minimal Ubuntu Server install with security updates]
apt-get update -y
apt-get install -y virtualbox-guest-dkms
[reboot]
[select Insert Guest Additions CD Image from Devices menu]
mount /dev/cdrom /mnt
/mnt/VBoxLinuxAdditions.run install
[reboot]
mkdir /mnt/<mount-point>
lsmod | grep vbox # [you should see the VBox additions]
mount -t vboxsf <mount-point> /mnt/<mount-point>

And add the following to /etc/fstab

/<mount-point> /mnt/<mount-point> vboxsf defaults 0 0

Ubuntu VMWARE

For Ubuntu 14.04, 16.04, and 18.04, open-vm-tools doesn't work, so do the following:

[minimal Ubuntu Server install with security updates]
[configure VM to have shared folder]
apt-get install -y make
apt-get purge open-vm-tools # on 16.04, remove the broken package
[select VMware Tools Installation from Virtual Machine menu]
mount /dev/cdrom /mnt
tar -xvzf /mnt/VMwareTools-x.y.z-nnnnnnn.tar.gz -C /tmp
/tmp/vmware-tools-distrib/vmware-install.pl
[do you still want to proceed with this installation? [no] YES]
[take the defaults for the rest of the choices]
[reboot and mount points will appear /mnt/hgfs/<mount-point>]

For Ubuntu 20.04, do the following:

[minimal Ubuntu Server install with the old installer]
[configure VM to have shared folder]
apt-get update -y
apt-get install -y open-vm-tools
[reboot]
mkdir /mnt/hgfs
mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other

Add the following to /etc/fstab

.host:/ /mnt/hgfs fuse.vmhgfs-fuse defaults,allow_other 0 0_

APPENDIX

adding submodule to git

This creates a HEADless snapshot of the submodule in the main repo.

cd ./macos
git submodule add https://github.com/mvilain/mac-dev-playbook.git

When you update the submodule and push it, the snapshot must be refreshed with the changes.

git submodule update
git submodule update --remote
git commit -a -m "submodule update"

removing submodules from git

Here's how to remove submodules (from How to delete a submodule)

• Delete the relevant section from the .gitmodules file.
• Stage the .gitmodules changes git add .gitmodules
• Delete the relevant section from .git/config.
• Run git rm --cached path_to_submodule (no trailing slash).
• Run rm -rf .git/modules/path_to_submodule (no trailing slash).
• Delete the now untracked submodule files rm -rf path_to_submodule
• Commit git commit -m "Removed submodule"
