The final operation you can do to remove the error is to ensure the hypervisor is configured to run automatically at computer startup. In order to make this configuration, you need to add an entry to the Boot Configuration Data (BCD) in Command Prompt.
Please pay attention to the item hypervisorlaunchtype. The status showing beside this item should be Auto, which means that hypervisor has been set to run at computer startup.
The two optional features you need to enable are Virtual Machine Platform and Windows Hypervisor Platform. These tools enable platform support for virtual machines and provide the necessary API to run virtualization software on Windows.
Although Windows Sandbox is a disposable environment, it functions just like any other virtual machine. Which means that the hypervisor on which it supposedly runs on fails to work if CPU Virtualization is disabled.
The final course of action that you have to take is to ensure that the hypervisor is configured to run at computer startup automatically. To do that, you must add an entry to the Boot Configuration Data (BCD) of your computer with the aid of the Command Prompt.
Restart your computer. Once again, launch an elevated Command Prompt console, type in BCDEDIT into the console, and then press Enter. On the list that shows up, the status next to hypervisorlaunchtype should read as Auto. That means the hypervisor is successfully configured to run at startup.
If you are still facing issues, try removing any third-party virtual machines from your computer (such as VirtualBox or VMWare), and then check again. The hypervisors used by these platforms can cause conflicts with the one used by Windows Sandbox, and is something you must take into consideration.
If Virtualization is shown as disabled here, go ahead to enable it in BIOS or UEFI setting.You also need to enable Hyper-V on your computer. Also, make sure that you have the SLAT or Second Level Address Translation support enabled on your CPU.2] Turn on Windows FeaturesWindows Sandbox can run successfully with the help of some operating system-based features.Do the following:Type Windows Feature in the search box.Choose Turn Windows features on or off among the listed apps to open it.Locate the features labeled Virtual Machine Platform and Windows Hypervisor Platform, and select the check boxes beside them.Click OK button to save changes.Reboot your computer to see if the No hypervisor was found with error code 0xc0351000 issue has been resolved.3] Ensure hypervisor is configured to run automatically at computer startupThis solution requires you to ensure the hypervisor is configured to run automatically at computer startup. In order to make this configuration, you need to add an entry to the Boot Configuration Data (BCD) in Command Prompt.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'thewindowsclub_com-banner-1','ezslot_7',819,'0','0']);__ez_fad_position('div-gpt-ad-thewindowsclub_com-banner-1-0');Do the following:Press Windows key + R to invoke the Run dialog.In the Run dialog box, type cmd and then press CTRL + SHIFT + ENTER to open Command Prompt as admin.In the command prompt window, type the command below and press Enter.BCDEDIT /Set current hypervisorlaunchtype autoReboot your computer and run Command Prompt again as above.Now type the command below and press Enter.bcdeditIn the output, ensure the item hypervisorlaunchtype status is showing Auto.

What had happened:I had to start an android emulator and Android Studio said that "Emulator is incompatible With Hyper-V" so it ran this command to disable hyper-v bcdedit /set hypervisorlaunchtype off
Nested Virtualization is supported both Azure and on-premises. However, if using a non-Microsoft hypervisor such as KVM, Microsoft can not provide end-to-end support. Please ensure your vendor supports this scenario.
The diagram below shows Hyper-V without nesting. The Hyper-V hypervisor takes full control of the hardware virtualization capabilities (orange arrow), and does not expose them to the guest operating system.
In contrast, the diagram below shows Hyper-V with nested virtualization enabled. In this case, Hyper-V exposes the hardware virtualization extensions to its virtual machines. With nesting enabled, a guest virtual machine can install its own hypervisor and run its own guest VMs.
The most commonly deployed type of hypervisor is the type 1 or bare-metal hypervisor, where virtualization software is installed directly on the hardware where the operating system is normally installed. Because bare-metal hypervisors are isolated from the attack-prone operating system, they are extremely secure. In addition, they generally perform better and more efficiently than hosted hypervisors. For these reasons, most enterprise companies choose bare-metal hypervisors for data center computing needs.
While bare-metal hypervisors run directly on the computing hardware, hosted hypervisors run on top of the operating system (OS) of the host machine. Although hosted hypervisors run within the OS, additional (and different) operating systems can be installed on top of the hypervisor. The downside of hosted hypervisors is that latency is higher than bare-metal hypervisors. This is because communication between the hardware and the hypervisor must pass through the extra layer of the OS. Hosted hypervisors are sometimes known as client hypervisors because they are most often used with end users and software testing, where higher latency is less of a concern.
Hardware acceleration technology can create and manage virtual resources faster by boosting processing speed for both bare-metal and hosted hypervisors. A type of hardware accelerator known as a virtual Dedicated Graphics Accelerator (vDGA) takes care of sending and refreshing high-end 3-D graphics. This frees up the main system for other tasks and greatly increases the display speed of images. For industries such as oil and gas exploration, where there is a need to quickly visualize complex data, this technology can be very useful.
A hypervisor is a crucial piece of software that makes virtualization possible. It creates a virtualization layer that separates the actual hardware components - processors, RAM, and other physical resources - from the virtual machines and the operating systems they run.
From a VM's standpoint, there is no difference between the physical and virtualized environment. Guest machines do not know that the hypervisor created them in a virtual environment or that they share available computing power.
A Type 1 hypervisor is a layer of software installed directly on top of a physical server and its underlying hardware. Since no other software runs between the hardware and the hypervisor, it is also called the bare-metal hypervisor.
This hypervisor type provides excellent performance and stability since it does not run inside Windows or any other operating system. Instead, it is a simple operating system designed to run virtual machines. The physical machine the hypervisor runs on serves virtualization purposes only.
Once you boot up a physical server with a bare-metal hypervisor installed, it displays a command prompt-like screen with some of the hardware and network details. They include the CPU type, the amount of memory, the IP address, and the MAC address.
Note: The hypervisor allocates only the amount of necessary resources for the instance to be fully functional. This is one of the reasons all modern enterprise data centers, such as phoenixNAP, use type 1 hypervisors.
VMware is an industry-leading virtualization technology vendor, and many large data centers run on their products. It may not be the most cost-effective solution for smaller IT environments. If you do not need all the advanced features VMware vSphere offers, there is a free version of this hypervisor and multiple commercial editions.
KVM is built into Linux as an added functionality that makes it possible to convert the Linux kernel into a hypervisor. It is sometimes confused with a type 2 hypervisor. However, it has direct access to hardware along with virtual machines it hosts.
This hypervisor has open-source Xen at its core and is free. Advanced features are only available in paid versions. Even though Oracle VM is a stable product, it is not as robust as vSphere, KVM, or Hyper-V.
Type 2 hypervisors run inside the physical host machine's operating system, which is why they are called hosted hypervisors. Unlike bare-metal hypervisors that run directly on the hardware, hosted hypervisors have one software layer in between. The system with a hosted hypervisor contains:
What makes them convenient is that they do not need a management console on another system to set up and manage virtual machines. Everything is performed on the server with the hypervisor installed, and virtual machines launch in a standard OS window.
Hosted hypervisors also act as management consoles for virtual machines. Any task can be performed using the built-in functionalities. Below is one example of a type 2 hypervisor interface (VirtualBox by Oracle):
As with bare-metal hypervisors, numerous vendors and products are available on the market. Conveniently, many type 2 hypervisors are free in their basic versions and provide sufficient functionalities. 2ff7e9595c
