VirtualBox: how to resize a virtual (dynamic) disk

The existing disk should be dynamic and not fixed.
Resize the existing virtual disk to ~50GB:

$ VBoxManage modifyhd disk_foo.vdi --resize 50000

Use GParted to allocated the free space to the existing partition: download the cd iso version of GParted, create a new virtual machine with virtual cd rom the GParted iso and set its disk the disk_foo.vdi. GParted linux distribution will boot, will recognize the disk disk_foo.vdi. Then from the GParted program allocate the free space to the existing partition.

VirtualBox: Resize vdi

Assume the hard disk of the existing vm old_small.vdi is full and we want to resize it.


Create a new vm with the hard disk size you want. Call it new_big (the output is called new_big.vdi).




Then execute the following cmd:

$ VBoxManage clonehd --existing old_small.vdi new_big.vdi

That's it ;)

VirtualBox: How to create a shared folder between Linux (Ubuntu) host os and Windows 7 or Linux (Ubuntu) guest os

Requirements: install Guest Additions and shutdown the vm

assume name of vm is WindowsVM and you want to share folder home/micharg/SharedVMFolder

on Linux (Ubuntu) Host OS:

$ mkdir /home/micharg/SharedVMFolder

$ VBoxManage sharedfolder add "WindowsVM" --name "SharedVMFolder" --hostpath "/home/micharg/SharedVMFolder"

$ VBoxManage startvm WindowsVM

on Linux (Ubuntu) Guest OS:

$ mkdir /home/vmuser/SharedVMFolder
$ sudo mount -t vboxsf -o uid=aromero SharedVMFolder /home/vmuser/SharedVMFolder

on Windows 7 Guest OS:

Nothing more to do ;) Just go to Network and you will see the shared the new shared folder SharedVMFolder in pc VBOXSRV

Resize a virtual machine (vdi)

Assume we want to resize small.vdi into big.vdi. Then create a new virtual machine (with gui or shell) with name big.vdi with the disk size of our will and execute the following command:

$ VBoxManage clonehd --existing /path/to/small.vdi /path/to/big.vdi

VirtualBox common shell commands

list all registered virtual machines:

$ VBoxManage list vms

Connect remotely to VM (RDP)

Enable RDP (Remote Desktop Protocol) for the vm you want to connect to:

$ sudo VBoxManage modifyvm vmName --vrde on

Connect to running vm:

$ rdesktop -a 16 192.168.0.100
