How to open a .VDI Virtual MachineSometimes someone share with us one Virtual machine with extension .VDI, after that we can wonder how and what with?Well the answer is... It is a VirtualBox - Virtual Machine.

Open the Virtual File Manager. 2. Click on Actions ? Add and select the .VDI fileClick "Ok"3. A new Virtual machine will be displayed, (in this Case, an OEL5 32GB Virtual Machine is available.)4. This step is important. Once you have open the settings, under General option click the advanced settings. Here you must change the default directory to save your Snapshots; my recommendation set it to the same directory where the .Vdi file is. Otherwise you can have the same Virtual Machine and its snapshots in different paths.5. Now Click on System, and proceed to assign the correct memory and define the processors for the Virtual machine. Note: Enable "Enable IO APIC" if you are planning to assign more than one CPU to the Virtual Machine.6. Associated the storage disk to the Virtual machineThe disk must be selected as IDE Primary Master. 7. Well you can verify the other options, but with these changes you will be able to start the VM. Note: Sometime the VM owner may share some instructions, if so follow his instructions.8. Click Ok and Push Start Button, and enjoy your Virtual Machine
