Creating a Test VM

1. Run the following command on the VirtualBox host to download the TinyCore Linux .iso
   sudo wget -O /home/vboxadmin/TinyCore-12.0.iso http://tinycorelinux.net/12.x/x86/release/TinyCore-12.0.iso
2. In the phpVirtualBox web UI, click New
3. Set the Name to TinyCore Linux, Type to Linux and Version to Other Linux (32-bit) > Click Next
4. Leave the memory at 256 MB > Click Next
5. Select Do not add a virtual hard disk > Click Create
6. Click Continue to confirm creating the VM with no virtual hard disk
7. Right click the TinyCore Linux VM > Settings...
8. Select Storage from the left navigation menu
9. Click on the empty optical drive
10. Click the choose disk image dropdown > Choose a virtual disk file...
11. Navigate to /home/vboxadmin/TinyCore-12.0.iso and select it
