bios关闭虚拟机(七彩虹主板怎么关闭虚拟化)

1. First open VMware, and then select a system whose CD needs to be booted, as shown below

2. After selecting the system, Click the small black triangle next to the green triangle in the picture above, and then choose to boot into BIOS, as shown below

3. In the Main option, change LegacyDisketteA : Set to "Disabled" to close the floppy drive

Press F10 to save and exit.

You can try the following solutions;
1. Have you installed the 360 ​​Security Guard - Core Crystal Protection function? Since 360 ​​Security Guard Core Crystal Protection uses the same virtualization technology as the virtual machine, resulting in The VT technology of the virtual machine cannot be used. Turn off the nuclear crystal protection function and it will be normal.
2. For win8 or above systems, the Hyper-V function needs to be turned off. The method of turning it off is as follows:
Quick entry: Control Panel-Programs and Features-Windows Functions, just uncheck Hyper-V

The reason why Intel virtualization technology is disabled in bios even after it is enabled in bios and the solution:

1. Whether the nucleation protection function is installed? The protection uses the same virtualization technology as the virtual machine, resulting in the VT technology of the virtual machine being unavailable.

Specific solution: Uninstall the corresponding nuclear crystal protection function to return to normal.

2. For win8 or above systems, the Hyper-V function needs to be turned off.

Specific solution: Hyper-V adopts a microkernel architecture, taking into account both security and performance requirements. The underlying Hypervisor of Hyper-V runs at the highest privilege level, which Microsoft calls ring-1 (and Intel calls it rootmode), while the OS kernel and driver of the virtual machine run in ring0, removing the Hyper-V function. .

Extended information:

The principle of intel virtualization technology:

A virtual machine is an abstraction and simulation of a real computing environment. VMM needs to allocate a set of data structures to each virtual machine to manage their status, including a full set of registers of the virtual processor, physical memory usage, virtual device status, etc. When the VMM schedules a virtual machine, it restores part of its state to the host system. Not all states need to be restored. For example, the host CR3 register stores the page table physical address set by the VMM, not the value set by the GuestOS.

The host processor directly runs the machine instructions of GuestOS. Since GuestOS runs at a low privilege level, when accessing the privileged state of the host system (such as writing the GDT register), insufficient permissions cause the host processor to generate an exception, which will The running rights are automatically returned to VMM. In addition, the arrival of external interrupts will also cause the VMM to run.
