- Make sure you have the administrative rights to execute certain commands.
- VirtualBox Extension Pack must be installed to access network features.
Essential commands to control your VMs
Once prepared, it’s time to use the command line to run and manage your virtual machines. Here are some key commands:
| 🔍 | Orders |
| ▶️ | VBoxManage startvm “VM_Name” –type headless |
| ⏸️ | VBoxManage controlvm “VM_Name” pause |
| 🔄 | VBoxManage controlvm “VM_Name” resume |
| 💻 | VBoxManage controlvm “VM_Name” poweroff |
| 🗑️ | VBoxManage unregistervm “VM_Name” –delete |
Create a new virtual machine via CLI
To go further, creating a new virtual machine can also be done via the command line. Here is an overview of the steps to follow:
- Create the virtual machine: VBoxManage createvm –name “VM_Name” –register
- Configure memory: VBoxManage modifyvm “VM_Name” –memory 2048
- Add a hard drive: VBoxManage createhd –filename “/path/to/disk.vdi” –size 50000
- Connect the disk and ISO: VBoxManage storageattach “VM_Name” –storagectl “SATA Controller” –port 0 –device 0 –type hdd –medium “/path/to/disk.vdi”
- Start the machine: VBoxManage startvm “VM_Name” –type headless
Complete the installation via RDP
To access your newly created VM once started, configure access RDP :
- Enable RDP: VBoxManage modifyvm “VM_Name” –vrde on
- Specify the port used: VBoxManage modifyvm “VM_Name” –vrdeport 3389
- Connect through your favorite RDP client with the IP address of your host machine.
