Error Virtualizing AMD-V/RVI on Certain Platforms with VMware Workstation Pro 17.5.1
VMware Workstation Pro 17.5.1 is a powerful virtualization platform that allows users to run multiple operating systems on a single physical machine. However, some users have encountered an issue where they cannot start a virtual machine without the "Virtualize Intel VT-x/EPT or AMD-V/RVI" option checked, even on systems with AMD processors.
Understanding Virtualization Technologies
To understand the issue, it is important to first understand the virtualization technologies involved. Intel VT-x and AMD-V are hardware virtualization technologies that allow virtual machines to access and use the underlying physical hardware directly. EPT (Extended Page Tables) and RVI (Rapid Virtualization Indexing) are memory management features that improve the performance of virtualized systems.
VMware Workstation Pro supports both Intel and AMD virtualization technologies, allowing users to create and run virtual machines on a wide range of hardware platforms. However, some users have reported issues with virtualizing AMD-V/RVI on certain systems, even when the hardware supports these technologies.
Identifying the Problem
The error message "Cannot start the virtual machine because the AMD-V feature is disabled in the system BIOS (or by the host operating system)" typically indicates that the system BIOS or operating system is not configured to support virtualization. However, some users have reported seeing this message even when the system is configured correctly.
Another possible cause of the issue is a conflict between VMware Workstation Pro and other software or drivers on the system. For example, some security software may disable virtualization to prevent malicious code from using virtual machines to bypass security measures.
Solving the Problem
The first step in solving the problem is to ensure that virtualization is enabled in the system BIOS. To do this, restart the system and enter the BIOS setup menu. Look for a setting related to virtualization, such as "AMD-V" or "SVM", and ensure that it is enabled.
If virtualization is already enabled in the BIOS, try disabling and re-enabling it. Some users have reported that this resolves the issue.
If the issue persists, try disabling any security software that may be conflicting with VMware Workstation Pro. Some security software includes options to disable virtualization or sandboxing features, which can cause conflicts with virtual machines.
If none of these solutions work, try updating the system BIOS or chipset drivers. Some users have reported that this resolves the issue, particularly on older systems.
The error message "Cannot start the virtual machine because the AMD-V feature is disabled in the system BIOS (or by the host operating system)" can be caused by a variety of issues, including incorrect BIOS settings, software conflicts, and outdated drivers. By following the steps outlined above, users can troubleshoot the issue and get their virtual machines up and running again.

// Example code block: Disabling and re-enabling virtualization in the BIOS
1. Restart the system and enter the BIOS setup menu
2. Look for a setting related to virtualization (e.g. "AMD-V" or "SVM")
3. Disable the virtualization setting
4. Save changes and restart the system
5. Repeat steps 1-3 to re-enable virtualization
