  #   # Display the VirtualBox GUI when booting the machine
      vb.gui = false
      vb.name = "VM-1"
  #   # Customize the amount of memory on the VM:
     vb.memory = "2048"

Since atlas.hashicorp.com is down, Vagrant file must be updated with the following line to download box from vagrantcloud.com :
```
Vagrant::DEFAULT_SERVER_URL.replace('https://vagrantcloud.com')
Vagrant.configure("2") do |config|
...
```

Resize disk (as root not vagrant sudo) :

# find process currently using /home
fuser -m /home

# kill processes (if any)
kill-9 XX

# unmount /home
umount /home

# Resize "/dev/mapper/VolGroup-lv_home" from 30Go to 5Go
fsck -f /dev/mapper/VolGroup-lv_home
lvresize -r -L1G /dev/mapper/VolGroup-lv_home

# Add 25Go to Resize "/dev/mapper/VolGroup-lv_root"
lvresize -r -L+29G /dev/mapper/VolGroup-lv_root

for centos, fuser is part of “psmisc” package

for Centos/RHEL >= 7

# find process currently using /home
fuser -m /home

# kill processes (if any)
kill-9 XX

#Backup folder
xfsdump -f /tmp/home.dmp /home

# unmount 
umount /home

# remove LV
lvremove /dev/mapper/centos-home

# recreate LV
lvcreate -l 800 -n home centos

# Format LV (XFS)
mkfs.xfs /dev/mapper/centos-home

# remount
mount -a

# restore backup
xfsrestore -f /tmp/home.dmp /home

# extend main LV to take 100%
lvextend -l +100%FREE /dev/mapper/centos-root

# Grow FS
xfs_growfs /dev/mapper/centos-root

# check result
df -h

Virtualbox CPU customization :

  config.vm.provider "virtualbox" do |vb|
    # Display the VirtualBox GUI when booting the machine
    vb.gui = false
    vb.name = "My New VM"
    #  # Customize the amount of memory on the VM:
    vb.memory = "20480"
    vb.cpus = 2
    # set video memory to 12M to avoid a VB warning message
    vb.customize ["modifyvm", :id, "--vram", "12"]
    vb.customize ["modifyvm", :id, "--cpuexecutioncap", "75"]
  end
