kvm-vm-tune is a CLI tool using libvirtwrap-go.

Features

• Check if a VM is running
• Set CPU count for a VM
• Set memory size for a VM
• Resize and expand VM disks
• Get a list of all defined VMs
• Get disk paths for a specific VM
• Verify if a disk belongs to a specific VM
• Attach disks to a VM
• Attach network interfaces to a VM

	"github.com/zinrai/libvirtwrap-go/pkg/vm"
)

func main() {
	myVM := vm.New("my-vm-name")

	running, err := myVM.IsRunning()
	if err != nil {
		log.Fatalf("Error checking VM status: %v", err)
	}

	fmt.Printf("VM is running: %v\n", running)

	err = myVM.SetCPUCount(2)
	if err != nil {
		log.Fatalf("Error setting CPU count: %v", err)
	}

	err = myVM.SetMemorySize("4G")
	if err != nil {
		log.Fatalf("Error setting memory size: %v", err)
	}

	fmt.Println("VM configuration updated successfully")
