libc++abi: terminating due to uncaught exception error while creating VM

[BhautikChudasama]

I am trying to create a VM for fun using vz using below code

package main

import (
	"fmt"
	"log"
	"os"

	"github.com/Code-Hex/vz/v3"
)

func main() {
	imgPath := "/Users/bhautik/workspace/src/simple-virt/ubuntu-22.04.1-live-server-arm64.iso"

	efiVarPath := "/tmp/efi_vars.fd"

	if _, err := os.Stat(efiVarPath); os.IsNotExist(err) {
		file, err := os.Create(efiVarPath)
		if err != nil {
			log.Fatalf("Failed to create EFI variable store file: %v", err)
		}
		file.Close()
	}

	efiVariableStore, err := vz.NewEFIVariableStore(efiVarPath)
	if err != nil {
		log.Fatalf("Failed to create EFI variable store: %v", err)
	}

	bootLoader, err := vz.NewEFIBootLoader(vz.WithEFIVariableStore(efiVariableStore))
	if err != nil {
		log.Fatalf("Failed to create EFI boot loader: %v", err)
	}

	config, err := vz.NewVirtualMachineConfiguration(bootLoader, 2, 4*1024*1024*1024) // 4GB RAM
	if err != nil {
		log.Fatalf("Failed to create VM configuration: %v", err)
	}

	err = addStorageDevices(config, imgPath)
	if err != nil {
		log.Fatalf("Failed to add storage devices: %v", err)
	}

	valid, err := config.Validate()
	if err != nil {
		log.Fatalf("Configuration validation failed: %v", err)
	}
	if !valid {
		log.Fatal("Configuration is invalid")
	}

	vm, err := vz.NewVirtualMachine(config)
	if err != nil {
		log.Fatalf("Failed to create virtual machine: %v", err)
	}

	err = startVM(vm)
	if err != nil {
		log.Fatalf("Failed to start VM: %v", err)
	}
}

func startVM(vm *vz.VirtualMachine) error {
	err := vm.Start()
	if err != nil {
		return fmt.Errorf("failed to start VM: %w", err)
	}

	return nil
}

func addStorageDevices(config *vz.VirtualMachineConfiguration, imgPath string) error {
	var storageDevices []vz.StorageDeviceConfiguration

	bootDiskAttachment, err := vz.NewDiskImageStorageDeviceAttachment(imgPath, true) // false = read-write
	if err != nil {
		return err
	}

	bootDiskDevice, err := vz.NewVirtioBlockDeviceConfiguration(bootDiskAttachment)
	if err != nil {
		return err
	}

	storageDevices = append(storageDevices, bootDiskDevice)
	config.SetStorageDevicesVirtualMachineConfiguration(storageDevices)
	return nil
}

I am getting below error:

libc++abi: terminating due to uncaught exception of type Base::bad_expected_access<void>: std::exception

I am running on Mac 15.4.1 (24E263) & M1 architecture. Can someone help me what i am doing wrong? Thanks.

What version of Code-Hex/vz are you using? This should be visible in go.mod
Are there more details before/after the error messae you pasted?
