Cannot Run Nested Virtualization on Windows 11 | "Virtualized AMD-V/RVI is not supported on this platform"

Recently I use upgraded both my mini pc to Windows 11. Everything running smoothly including Vmware Workstation with a few VMs running. However, I found an issue when want to run nested virtualization - Hyper-V.

Error message:

"Virtualized AMD-V/RVI is not supported on this platform"


Here is my tweak to make it work:

1. Uninstall Windows Hypervisor Platform

Go to Control Panel | Programs and Features | Click Turn Windows features on or off

Uncheck the Windows Hypervisor Platform



2. Edit Local Group Policy

Type mmc | Add Group Policy Object | Local Computer

Go to Computer Configuration | Administrative Templates | System | Device Guard | Click on Turn on virtualization Based security | Set to Disable 

Then restart your machine and test run nested virtualization.

That should do the trick!

How to Reduce Memory Usage on Windows 11?

I just upgraded my both machines from Windows 10 to Windows 11. I find out that initial memory after boot up has used around 6GB memory. You can view it from Task Manager.

Here is my fine-tuning and success to reduce around 3GB of memory.

1. Disable start-up program. Microsoft runs a few applications in the background.

-> Use Task Manager | Start up | Disable unwanted programs such as Cortana, MS Team, Onedrive

2. Go to System Properties | Advanced Tab | Settings

-> Under Visual Effect, set Adjust for best performance

3. Modify the registry key

-> Type Regedit

-> Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

Set ClearPageFileAtShutDown to 1

Restart the machine

Check again the memory usage using Task Manager. Do you get from 6GB to around 3GB? 

Hope this trick helps to reduce your memory usage when upgrading to Windows 11.

Note: These settings are applicable after the upgrade to Windows 11 or the initial setup. Not apply when you install more program and run more on start up application.

Unable to Connect to Google Cloud SQL

 You've just created a MySQL on Google Cloud. However, was not able to access it via MySQL Workbench.


Tried to enable Private IP and use VPC and Public IP, but still failed.

Workaround is

1. Go to Connections > Networking > Public IP

2. Add Network | Put a name

3. Put CIDR of your public network. Example: 34.124.242.59.

Enter:

34.124.242.0/24


4. Save

5. Try accessing again using MySQL Workbench.

Another trick.

1. Go to Connection > Security

2. Check Allow only SSL Connection

Wait for changes to apply

3. Set again root password

Wait for changes to apply

4. Uncheck Allow only SSL Connection

Wait for changes to apply


5. Test access again
