Proxmox Virtual Machines

Creating a Virtual Machine (VM)

Steps:

  1. Upload ISO to local or local-lvm storage.

  2. Go to Create VM in the Proxmox Web GUI.

  • General: - Name: e.g.:ubuntu-server

  • OS: - Select the uploaded ISO image

  • System: - Use default (UEFI or BIOS)

  • Hard Disk:

  • Choose local-lvm

  • Set desired disk size

  • CPU & Memory: - e.g.: 2 cores, 4GB RAM

  • Network: - Select vmbr0 (bridge to LAN)

  • Confirm and finish the VM creation wizard.

Post-VM Setup:

  1. Start the VM.

  2. Install your chosen OS (e.g., Ubuntu, Debian, Windows).

  3. Inside the guest OS:

    • Set a static IP address
    • Install the Proxmox guest agent:
apt update && apt install qemu-guest-agent -y
systemctl enable --now qemu-guest-agent

VM Templates

Using and Creating Templates

Creating VM templates allows you to rapidly deploy new virtual machines based on a pre-configured image.

Steps to create a VM template:

  1. Create and configure a VM

    • Install the desired OS (e.g., Ubuntu minimal)
    • Configure the VM settings, install software, and perform updates as needed

  2. Shutdown the VM

    • Ensure the VM is powered off before proceeding

  3. Convert the VM to a template

    • In the Proxmox Web GUI, right-click the VM
    • Select Convert to Template

Note

You can also use Proxmox Shell to comvert a VM to a template: 

qm template <vmid>

Using VM Templates

  • When creating a new VM, select Clone and choose the template as the source
  • You can create either a full clone or a linked clone depending on your storage and performance needs

✅ Using templates streamlines VM deployment and maintains consistency across your virtual infrastructure.
