Introduction :

Hyper-V is a powerful virtualization platform built into Windows, allowing users to create and manage virtual machines (VMs) easily. However, during the process of creating a VM, users may encounter various errors that prevent successful deployment. One common issue is the error:

"Virtual machine could not be created. The operation failed."

Let’s explore why this happens and how to fix it step by step.

Common Error Message :

Causes of the Error :

  1. Hyper-V Services Not Running

  2. Corrupted Virtual Switch or Configuration

  3. Insufficient Permissions

  4. Conflicting Software (e.g., VMware, VirtualBox)

  5. Missing CPU Virtualization Support in BIOS

  6. Insufficient Disk Space

How to Fix the Error :

1. Ensure Hyper-V Services Are Running

Open PowerShell or Command Prompt as Administrator and run:

2. Restart Hyper-V Management Service

  • Find Hyper-V Virtual Machine Management

  • Right-click → Restart

3. Check Virtualization in BIOS

  • Reboot your system

  • Enter BIOS (usually Del, F2, or Esc)

  • Enable Intel VT-x or AMD-V

4. Run as Administrator

Always launch Hyper-V Manager as Administrator to avoid permission issues.

5. Delete and Recreate Virtual Switch

  • Open Virtual Switch Manager

  • Delete the current switch and create a new External Switch

6. Check Disk Space

Ensure the disk where you store VM files has enough space (at least 10–20 GB free).

Alternative Solution: Re-register Hyper-V Components

Open PowerShell as Admin and run:

Still Facing the Issue?

Try creating the VM using PowerShell:

New-VM -Name "TestVM" -MemoryStartupBytes 2GB -BootDevice VHD -NewVHDPath "C:\VMs\TestVM.vhdx" -NewVHDSizeBytes 20GB -Path "C:\VMs"

Final Tip: Check Event Viewer

Navigate to:

Event Viewer → Applications and Services Logs → Microsoft → Windows → Hyper-V-VMMS

Look for critical errors or failed tasks.

Conclusion

Hyper-V is robust, but errors during VM creation can be frustrating. By following these steps, you should be able to identify and resolve the issue efficiently.
