Build vagrant box from an existing one

cd homestead
vagrant package --output ../boxes/homestead.box
vagrant box add homestead_100gb ../boxes/homestead.box
cd ..
mkdir homestead_100gb
vagrant init # or copy VagrantFile from somewhere else and change config.vm.box to "homestead_100gb"
vagrant up # to confirm that it works
vagrant destroy

Resize the .vmdk image

cd ~/.vagrant.d/boxes/homestead_100gb/0/virtualbox
VBoxManage clonehd "box-disk1.vmdk" "clone-disk1.vdi" --format vdi
VBoxManage modifyhd "clone-disk1.vdi" --resize 102400
VBoxManage showhdinfo "clone-disk1.vdi"
VBoxManage clonehd "clone-disk1.vdi" "box-disk1.vmdk" --format vmdk
mv box-disk2.vmdk box-disk1.vmdk
rm clone-disk1.vdi
