Test your Virtualbox Installation

This page helps you to test if your VirtualBox install is ok.

Install VirtualBox

If not already done, install VirtualBox on your computer. You can follow the instructions given here by the DISI.

Test your installation

For testing VirtualBox, we have developed a small virtual image that should run smoothly on your computer. Follow the following steps:

  • Download TestVM.ova from this link.

  • Import TestVM.ova: Menu File > import appliance, then select TestVM.ova and hit next and finalize hitting "Import" - (help)

Import the VM

  • You now see the TestVM virtual image on the left
  • Select it and hit the "Start" button

Start the VM

  • Wait and look at the screen: when the virtual machine has finished to boot, you should obtain the following result:

The result that should be obtained

If some tests fail, please find your problem below and a possible solution.

  • Shutdown the VM

Shutdown the VM

You are now ready with your VirtualBox installation :)

Problems and solutions

The VM does not start and Virtualbox displays an error

VT-X is missing

VT-X is missing

You should enable the intel VT-x instructions in your BIOS.

In windows 10, you should:

  • go to the update screen of Windows
  • reboot into the BIOS
  • activate intel VT-x

This page should help you.

Error: vboxnet0 (adapter 2)

vboxnet0 missing

The VM does not start because the private network vboxnet0 have not been created.

  • Go to File > Host network manager
  • Create the vboxnet0 network using the Create button

create vboxnet0

Error: Failed to create a host network interface

error creating vboxnet0

It seems that the installation of VirtualBox was done with wrong options. Try to uninstall VirtualBox and install it again. It should solve this problem.

USB problem

You should install the extension pack. Go on this page and click the VirtualBox X.Y.Z Oracle VM VirtualBox Extension Pack and follow the instructions.

The VM starts and it shows an error

Pinging 8.8.8.8 fails

Your VM cannot access internet. It is probably due to your computer that is not connected to internet or your traffic is filtered. Try to reconnect to internet or change of network provider and recheck.

DNS resolution fails

If you can ping 8.8.8.8 is ok and the DNS resolution fails, it is a strange problem. It means that the DNS server embedded in VirtualBox cannot send DNS request outside. It should not happen. Try to change of network provider.

DHCP is blocked and the test does not continue

dhcm is blocked

This is because your virtual network card has been disabled or misconfigured. Go to "Paramètres", then "Réseau" and activate the network card in NAT mode:

eth0

There is an error about eth1

eth1 is not there

Probably, you have misconfigured the second network card: this network card is connected to the private host vboxnet0. You should configure it as follows (Paramètres > Réseau):

eth1

If vboxnet0 is missing go to the previous error "vboxnet0 is missing".

Other problems

Cannot exit the mouse from the VM

By default the key "Ctrl" on the right, asks Virtualbox to exit from the VirtualBox window. If your keyboard has no right Ctrl key, you should customize the key in the preferences of Virtualbox.

The screen of the VM is very small

It is really difficult to read the screen !

You can increase the screen size by going into the menu:

Screen > Virtual screen number 1 > Resize to 125%
