Creation CLI Template

# 1. Create a new empty VM
qm create 101 --name ubuntu-test --memory 2048 --cores 2 --net0 virtio,bridge=vmbr0 --ostype l26 --scsihw virtio-scsi-pci

# 2. Attach an ISO (install image)
qm set 101 --cdrom local:iso/ubuntu-22.04.iso

# 3. Add a virtual hard disk
qm set 101 --scsi0 local-lvm:32   # 32GB disk on storage 'local-lvm'

# 4. Enable boot from ISO
qm set 101 --boot order=scsi0,cdrom

# 5. (Optional) Enable QEMU Guest Agent (if OS supports it)
qm set 101 --agent enabled=1

# 6. Start the VM
