AMD’s virtualization technology is known as AMD-V, or Secure Virtual Machine. When attempting to launch a virtual machine (VM). You will receive the AMD-V Is Deactivated in the BIOS issue if this feature is disabled in the system’s firmware.
Virtual Machines can still be used if AMD-V is not enabled. There are significant restrictions if you decide to go down this road, though.
Since 64-bit guest OSes are incompatible and more CPU cores cannot be assigned to the VM, performance will be poor.
If your motherboard and CPU are up to date, they should already support AMD-V, so you can skip the hassle and just turn it on in the BIOS. In the following sections, we’ve laid out in full the steps you need to take to do this.
3 Ways to Fix “AMD-V Is Disabled in the BIOS” Error [Partition Manager]
Users have reported that while trying to launch a virtual machine in VM VirtualBox, they receive the error message “AMD-V is deactivated in the BIOS (or by the host OS)” (VERR SVM DISABLED).
This is a widespread problem across all versions of Windows 10, 8, and 7. The research indicates that Linux is where you will most frequently see this issue.
Solution 1: Enable Secure Virtual Machine Mode on the BIOS
The VERR SVM DISABLE error number indicates that your PC is capable of running AMD-V.
But the feature has been disabled in the BIOS. Simply power on the machine to enter the BIOS setup screen.
Security Virtual Machine Mode is a feature available on AMD-compatible motherboards.
To discover the Advanced CPU options in our AORUS x570 board’s Tweak tab, for instance, we would need to switch to the expert mode.
Then, turn on the feature called “Secure Virtual Machine Mode” by searching for it.
Once the changes have been saved and the machine has been rebooted, virtualization should be up and running, especially on brand new PCs.
If your virtual machine still won’t boot after you’ve tried the above, move on to the next fix.
Solution 2: Disable Windows Hyper-V
Recent releases of Windows all come equipped with Microsoft’s own virtualization technology, known as Hyper-V.
It’s possible that AMD-V technology will be disabled as soon as Microsoft Hyper-V is enabled.
The Microsoft Hyper-V service must be turned off in this instance. Take a look at this manual for assistance:
Step 1: Launch the Run dialogue by pressing the Windows key + R, then enter “cpl” and hit Enter.
Step 2: Click the Turn Windows features on or off link on the left side of the Programs and Features window.
Step 3: Click OK on the Windows Features dialogue to disable Hyper-V.
Solution 3: Change the Number of CPU Cores to 1
Forcing VirtualBox to produce a virtual machine with more than one CPU core will necessitate the use of hardware virtualizations.
The virtualization process will fail with the message “AMD-V is disabled in the BIOS” if your system configuration does not support the AMD-V technology.
To fix this problem, reduce the number of CPU cores to 1. Take a look at this manual for assistance:
Step 1: To change the settings for the machine throwing the problem, launch Oracle VM VirtualBox and right-click on it.
Step 2: Navigate to your virtual machine’s Settings > System > Processortab. Set the Processor(s) slider to 1, and then click OK.
Step 3: Exit the configuration menu and reboot the virtual machine.
In order to enable virtual technology in a BIOS, specific steps may need to be taken, which may differ from one motherboard and BIOS version to the next.
However, you can check the Virtualization Technology option in the BIOS menus, enable virtualization support in the operating system, and update any required software by following these steps:.
