NOTE 2019 Update:

• <any> Guard

• Containers

• Hyper-V

• Virtual Machine Platform

• Windows Sandbox

• Windows Subsystem for Linux (WSL)

ERROR # 1: Failed to Import Appliance

If you get the following error:

1. Move the .vmdk file to your second (bigger) disk. To do this click on "Global tools", choose the correct vmdk file and select move. It requires few minutes to do it.

2. Create a new virtual machine clicking on the new button.

3. Select Linux -> Ubuntu 64 bit.

4. Choose either 8192 or 4096 megabytes of RAM. Rule of thumb is half of your installed RAM.

5. On the next screen choose "Use an existing fixed virtual disk" and selected the just created .vmdk file

If for some reason this doesn't work. Try this:

1. Go the properties:

2. Click on remove to delete your virtual hard disk

3. Do the procedure of importing the virtual machine again from the start (only once) and you will get the error again. 

4. Then try the above procedure again

Alternative option:

• Import OVA using VMWare

ERROR # 2: Failed to open a session for the virtual machine Deep Learning CV Ubuntu

Implementation of the USB 2.0 controller not found!

Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 2.0 support in the VM settings.

Note! This error could also mean that an incompatible version of the 'Oracle VM VirtualBox Extension Pack' is installed (VERR_NOT_FOUND).

SOLUTION HERE - https://www.virtualbox.org/ticket/8182

Simply:

• Right click on the vm image > USB > USB 1.1

ERROR # 3 - Broken links to shared folder

Ignore those messages and if needed setup your own shared folder (see Lecture 9).

ERROR # 4 - On Macs it's advised you install the feature the feature pack for virtualbox

ERROR # 5 (Common) - VirtualBox fails with “Implementation of the USB 2.0 controller not found” after upgrading

Disable USB Controller when first loading if USB Error. Uncheck the Enable USB Controller box.

Then after loaded up, install the Guest Additions by finding it here from the top toolbar menu.
