Fix VMware Workstation Unrecoverable Error (vcpu-0)!

Here's how to Fix VMware Workstation Unrecoverable Error (vcpu-0).

VMware Workstation Unrecoverable Error (vcpu-0) is an error that occurs when you try to run a virtual machine in VMware Workstation or VMware Player. This error prevents you from starting or accessing your virtual machine. Some of the possible causes and solutions for this error are:

- **Another virtualization software is running at the same time**: This error can occur if you have another virtualization software, such as VirtualBox, running in the background. You need to close all other virtualization programs before opening a virtual machine in VMware Workstation or VMware Player. You can also check the Task Manager and see if any process related to other virtualization software is running. If so, you need to end it.
- **Secure Virtual Machine (SVM) is disabled from BIOS/UEFI**: This error can occur if Secure Virtual Machine (SVM) is disabled from your BIOS or UEFI settings. SVM is a feature that enables hardware virtualization and allows you to run multiple operating systems on the same processor. You need to enable SVM from your BIOS or UEFI settings before running a virtual machine in VMware Workstation or VMware Player.
- **Simultaneous Multithreading (SMT) is enabled from BIOS/UEFI**: This error can occur if Simultaneous Multithreading (SMT) is enabled from your BIOS or UEFI settings. SMT is a feature that allows a processor to execute multiple threads at the same time. However, SMT can cause conflicts with some virtualization software, such as VMware Workstation or VMware Player. You need to disable SMT from your BIOS or UEFI settings after enabling SVM in order to avoid any conflicts.
- **CPU or other component is overclocked**: This error can occur if your CPU or other component is overclocked. Overclocking is a process of increasing the clock speed of a component beyond its factory settings in order to improve its performance. However, overclocking can also cause instability and errors in some applications, such as VMware Workstation or VMware Player. You need to stop overclocking your CPU or other component or lower the clock speed to its default value before running a virtual machine in VMware Workstation or VMware Player.
- **VMware bug**: This error can also occur due to a bug in VMware Workstation or VMware Player. This bug was supposedly fixed with version 12.5, so you need to update your VMware software to the latest version available. You can check for updates by opening VMware Workstation or VMware Player and clicking Help - Software Updates. After installing the updates, you need to restart your system and then try running your virtual machine again.

i. There are a few things you can do to fix the VMware "the host does not support virtualizing real mode" error.

1. *Check your CPU's virtualization capabilities.* The error message "the host does not support virtualizing real mode" means that your CPU does not support the Intel VT-x or AMD-V virtualization technologies. To check your CPU's virtualization capabilities, open the Task Manager and go to the Performance tab. Under the "Processor" section, look for the "Virtualization" entry. If it says "Enabled," then your CPU supports virtualization. If it says "Disabled," then you will need to upgrade your CPU or use a different virtualization software that does not require virtualization support.
2. *Update your VMware software.* If your CPU supports virtualization, then the problem may be that your VMware software is out of date. To update your VMware software, go to the VMware website and download the latest version. Once you have downloaded the latest version, install it and try to create your virtual machine again.
3. *Use a different virtualization software.* If you have tried the above steps and you are still getting the error message, then you may need to use a different virtualization software. There are a number of free and open-source virtualization software options available, such as VirtualBox and QEMU.

Here are some additional tips for fixing the VMware "the host does not support virtualizing real mode" error:

* Make sure that you are using a supported version of VMware software.
* Make sure that your CPU supports virtualization.
* Update your BIOS or UEFI firmware.
* Disable any security software that may be interfering with VMware.
* Try creating the virtual machine on a different computer.

If you are still having trouble fixing the error, you can contact VMware support for help.
