I need help. My virtualbox always has the hardware acceleration problem.

[qqqqqqqqq]

The error message is this:
VT-x/AMD-V hardware acceleration is not available on your system. Certain guests (e.g. OS/2 and QNX) require this feature and will fail to boot without it.

I know that some common fixes include turning off Hyper-V and enabling virtualization, however, I don't see Hyper-V in windows features, and I already enabled IOMMU in my Gigabyte UEFI.
After enabling IOMMU, I still encounter the hardware acceleration error. When I press continue, it just freezes with a windows logo. I can't turn off Hyper-V for an easy fix because I simply don't see it. When I uncheck the box for hardware acceleration in the acceleration tab of the system settings for my virtual environment, I still get this error message and the OS doesn't boot.

This is what the logs say:

00:00:07.983660 GIM: HyperV: Resetting MMIO2 regions and MSRs
00:00:07.984847 Changing the VM state from 'DESTROYING' to 'TERMINATED'
00:00:07.986287 Console: Machine state changed to 'PoweredOff'

Hyper-V is mentioned in the logs, so I think that Hyper-V might be hidden somewhere in the computer.

Please help me I've been spending hours on this.

Please zip and attach the full log, this will help us figure out what may be going on.

Also consider this info from viewtopic.php?f=6&t=93341#p449871

Look in the "Control Panel" » "Programs and Features" » "Turn Windows features on or off", and make sure that the none of the following are active:

• Application Guard
• Credential Guard
• Device Guard
• <any> * Guard
• Containers
• Hyper-V
• Virtual Machine Platform
• Windows Hypervisor Platform
• Windows Sandbox

If that doesn't work, enter the following command:

• 
  bcdedit /set hypervisorlaunchtype off

followed by a cold boot, i.e. shut down the computer, pull the power plug for 10", reboot.

After enabling IOMMU, I still encounter the hardware acceleration error

That's because the IOMMU has nothing to do with hardware acceleration.

Does it have anything to do with the virtualization? I have a gigabyte uefi and I can't find the hardware acceleration setting and the virtualization setting.

The setting you are looking for in the BIOS setup will be something like "Hardware virtualisation", "Virtualisation" or something mentioning VT-x (for Intel CPU based systems) or AMD-V for AMD systems.

If you want us to give a more in depth diagnosis of the issue you are having then zip the full log file and attach it to the thread rather than just posting a random few lines.

The logs seem straightforward: AMD-v (since you have an AMD processor) is disabled in the host BIOS. The BIOS option will be called AMD-v, or "Virtualization technology", or something of that nature. It'll probably be in the security settings in the BIOS, but that's just a guess.

I managed to find this out in three steps...

1. VBox.log states - DMI Product Name: AB350M-DS3H

2. Google AB350M-DS3H tells me it is a Gigabyte GA-AB350M-DS3H

3. Three clicks takes me to the user manual which states:

SVM Mode
Virtualization enhanced by Virtualization Technology will allow a platform to run multiple operating systems
and applications in independent partitions. With virtualization, one computer systemcan function asmultiple
virtual systems. (Default: Disabled)
