How to resize/convert a Vagrant VMDK volume to VDI

Using Vagrant and Virtual box is very easy, but most boxes have very little space provisioned for the root volume, these steps will show how to covert your storage from a VMDK (Virtual Machine Disk) to a VDI (Virtual Disk Image), then expand that disk to a more appropriate size.


-make certain you have available space on your host machine prior to starting this exercise.


$ cd VirtualBox\ VMs/
$ ls
vagrants_oraclelinux1_testdb

$ cd vagrants_oraclelinux1_testdb/

$ ls

$ VBoxManage clonehd box-disk1.vmdk box-disk1.vdi -format VDI

$ ls

--note
at this point you can remove/release the vmdk volume from your Virtual Machine. either delete the file on the OS or remove it from your VM console.
