无法启动虚拟化因为虚拟机管理程序未运行

原本虚拟机是能够运行的，突然一天发现不能运行了，提示：“无法启动虚拟化因为虚拟机管理程序未运行”

原本虚拟机是能够运行的，所以可以排除硬件等问题

运行这个后可以了：net start hvboot 说明这个服务没有自动运行

问题是之前都是可以自动运行的啊，

sc config hvboot start=auto

似乎也没有起作用直接修改注册表

1. Open the registry editor by typing “regedit” in the run window.

Locate the key,

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceshvboot and then set the start value of it to 2（自动）.

[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/hvboot]“Start”=dword:00000002

Start property can hold the following values.

Now you will have the hibernate and sleep facilities until you start the Hyper-V services in your machine.

2. Type the following command in a command prompt window with administrative rights.

sc config hvboot start= auto

Note that there needs to be a space between the = sign and the word demand.
