Solutions of VT Problem

How to Enable Virtualization technology

#Why do you need to enable virtualization technology?#

MEmu App Player will have better performance if hardware virtualization technology (aka Intel-VT, vt-x, AMD-V) is enabled on your computer. Most of mainstream Intel and AMD CPUs support this feature.

#Check if your CPU supports VT (Virtualization Technology)#

If it’s not enabled properly, we recommend you to enable it by following steps:

1. Download a 3rd-party tool: LeoMoon CPU-V to detect your CPU’s capability.

2. If get the result as below, that means your CPU is too old… bad news ?

3. If get the result as below, you need to enable this feature in BIOS by yourself.

#How to enable VT (Virtualization Technology) in BIOS#

Step 1. Press a designated key repeatedly (depends on your machine vendor, e.g. F2 or Del works for most Dell) to enter into BIOS setup page when system powers up.

Note: For some Lenovo laptop (Idea), there is a NOVO button to enter into system configuration. More details: Introduction to NOVO button

Note: For Windows 8.1 or 10, you can also manage to enter into BIOS in another way. More details: How to enter into BIOS in Windows 10

Step 2. Look for virtualization technology (aka Intel VT or AMD-V) and enable it. In the end, save and restart the computer to apply the change.

Note: The BIOS settings for Intel VT or AMD-V are usually in the Chipset or Processor menus. The menu names may vary from this guide, the virtualization settings may be found in Security Settings or other nonstandard menu names.

4. If get the result as below, you are probably ready to go with hardware virtualization now.leomoon-2green

If you still get the warning, there could be some conflicts in system settings or 3rd party software. Therefore, you may need to manually disable the settings.

 

#Check if Hyper-v is disabled in Windows system#

If you have Windows Hyper-V (an optional feature of Windows), please turn it off and reboot the system. Sometimes, it will be turned on after a certain Windows update.

Windows 10 users please make sure the Memory Integrity feature is turned off as well.

 

#Check if Third-Party software conflicts on VT such as AVAST#

As some friends report, they will get a warning of hardware-assistant virtualization (VT) feature disabled when start MEmu, although they have already enabled it in BIOS and verified it with LeoMoon Tool.

If you by chance installed AVAST antivirus on your machine, please try to follow the steps below.

Go Settings->Troubleshooting, disable self-defense module.

  1. Search for the file “C:\ProgramData\AVAST Software\Avast\avast5.ini” and open it in Notepad as admin. In the section “[Common]”, add “VirtualizationMechanisms=0” without quotes.

Particularly, for some old version AVAST, you only need to disable hardware-assisted virtualization in Troubleshooting settings.

Many thanks to Pavel Blahout’s great sharing! 

Note: AVAST is not only one antivirus software that occupies hardware-assisted virtualization feature exclusively. So try to find a similar setting if you install some other antivirus software.
