如果您 在 Hyper-V 中安装了 Windows 11(installed Windows 11 in Hyper-V)，但 虚拟机启动速度很慢(virtual machine is very slow to start)，这里有一些调整可能会加快速度。虽然有几件事是造成这种缓慢的原因，但这些常见的更改可能对您很方便。无论您安装的是Windows 11还是Windows 10，您都可以在两个版本中应用这些调整。
无论您使用 Hyper-V 还是VirtualBox或任何其他虚拟机软件，它们都取决于您已经拥有的硬件。如果您的计算机没有良好的处理器或足够的RAM，那么您在部署虚拟机时可能会遇到此类问题。假设您有一台不错的计算机，则可以遵循这些提示和技巧。
Hyper-V 虚拟机启动很慢
如果您的 Hyper-V 虚拟机启动速度很慢，请按照以下步骤加快速度。
- 添加更多内存
- 添加更多虚拟处理器
- 禁用 Windows 搜索服务
- SSD代替HDD
- 启用访客服务
- 检查硬盘健康
要了解有关这些解决方案的更多信息，请继续阅读。
如何加速 Hyper-V 虚拟机？
1]添加更多内存
(RAM)无论您安装的Windows版本如何， (Windows)RAM都是使启动更顺畅的原因。话虽如此，如前所述，使用少量RAM可能会导致速度变慢。(RAM)因此，最好提供至少 1/3 的原始RAM以使其运行顺畅。例如，如果您有 16GB 的内存，则应至少提供 5GB。如果您还没有这样做，请执行以下操作：
- 右键单击(Right-click)虚拟机并选择 Settings。
- 切换到 左侧的内存 选项卡。(Memory )
- 在相应的框中设置 RAM。
- 单击 确定 (OK )按钮。
现在，检查它是否解决了您的问题。
2]添加更多虚拟处理器
像RAM一样，它需要为您的虚拟机提供充足的处理能力。始终拥有一两个虚拟处理器内核可能还不够——尤其是当您使用Windows 11时。因此，最好提高处理能力并检查它是否解决了您的问题。为此，请执行以下操作：
- 在您的计算机上打开Hyper-V 管理器。(Hyper-V Manager)
- 右键单击(Right-click)虚拟机并选择“ 设置” (Settings )选项。
- 转到 处理器 (Processor )选项卡。
- 增加虚拟处理器的数量。
- 单击 确定 (OK )按钮。
- 重新启动您的虚拟机。
3]禁用Windows搜索服务
这里的目标是通过禁用一些功能强大的服务和应用程序来改善您的CPU资源。(CPU)Windows Search是在后台连续运行的服务之一。因此，您可以停止此服务并检查是否有任何改进。
- 在任务栏(Taskbar)搜索框中搜索 服务(services)，然后单击结果。
- 双击 Windows 搜索 (Windows Search )设置。
- 单击 停止 (Stop )按钮。
- 单击 确定 (OK )按钮。
现在检查问题是否仍然存在。
4] SSD代替HDD
您应该将 Windows 与 SSD 一起使用有几个原因 ，而且在速度方面， SSD(SSD outranks HDD) 每次都超过 HDD。因此，如果您已将主机操作系统安装在HDD上，则最好切换到SSD。可以 将您的操作系统从 HDD 迁移到 SSD(migrate your OS from HDD to SSD) ，而不会丢失数据或重新安装操作系统。
5]启用访客服务
在加速Hyper-V虚拟机时，启用访客服务非常方便。(Guest)默认情况下，Hyper-V不启用它，以下是打开它的步骤：
- 右键单击(Right-click)Hyper-V中的虚拟机。
- 选择 设置 (Settings )选项。
- 转到 集成服务 (Integration Services )选项卡。
- 勾选 访客服务 (Guest services )复选框。
- 单击 确定 (OK )按钮。
现在，检查您是否可以比以前更快地启动虚拟机。
6]检查硬盘健康
如果您的硬盘健康状况不佳，perforce 将反映在Hyper-V虚拟机上。因此，最好先 使用 HDD Expert 应用程序检查 HDD 健康状况(check the HDD health using HDD Expert) 。如果它显示任何错误或问题，您必须采取相应的步骤。
阅读(Read)：应用程序在尝试更改状态时遇到错误(The application encountered an error while attempting to change the state)– Hyper-V 错误。
以下是您可能遇到的一些问题的答案。
为什么我的虚拟机运行这么慢？
有几件事可以使您的计算机上的虚拟机变慢。您可以分配至少 1/3 的RAM、两个核心虚拟处理器等。另一方面，不要忘记检查硬盘驱动器的健康状况并在Hyper-V中启用(Hyper-V)访客(Guest)服务。
我应该给虚拟机多少内存？(RAM)
建议为您的 Hyper-V 虚拟机提供至少 1/3 的物理RAM。如果您有 16GB 的RAM，则应为虚拟机分配至少 5GB 的内存。无论您安装 Windows 10 还是 11，此计算都不会发生显着变化。
(Does)运行虚拟机会减慢您的计算机速度吗？
部分，是的。运行虚拟机可能会降低主机速度，因为虚拟机一直在消耗CPU资源。但是，如果您可以调整上述设置，您可能不会发现性能下降幅度很大。
虚拟机有多慢？
与主机相比，虚拟机总是较慢。换句话说，如果您提供相同的CPU资源来安装虚拟机和本地安装操作系统，您会发现虚拟机存在一些性能滞后。没有具体的百分比，因为它取决于硬件的质量。
就这样！
Hyper-V virtual machine very slow to start? Speed up Hyper-V!
If you have installed Windows 11 in Hyper-V, but the virtual machine is very slow to start, here are some tweaks that might speed it up. Although several things are responsible for this slowness, these common changes might be handy for you. Whether you have installed Windows 11 or Windows 10, you can apply these tweaks across both versions.
Whether you use Hyper-V or VirtualBox, or any other virtual machine software, they all depend on the hardware you already have. If your computer doesn’t have a good processor or enough RAM, you might get such issues while deploying a virtual machine. Assuming that you have a decent computer, you can follow these tips and tricks.
Hyper-V virtual machine very slow to start
If your Hyper-V virtual machine is very slow to start, follow these steps to speed it up.
- Add more RAM
- Add more virtual processor
- Disable Windows Search service
- SSD instead of HDD
- Enable Guest services
- Check hard disk health
To learn more about these solutions, continue reading.
How to speed-up Hyper-V virtual machine?
1] Add more RAM
RAM is what makes the startup smoother irrespective of the Windows version you have installed. Having said that, employing a low amount of RAM might cause slowness, as mentioned. Therefore, it is better to provide at least 1/3 of your original RAM so that it runs smoothly. For instance, if you have 16GB of Memory, you should provide at least 5GB. If you haven’t done that yet, do the following:
- Right-click on the virtual machine and select Settings.
- Switch to the Memory tab on the left side.
- Set the RAM in the respective box.
- Click the OK button.
Now, check if it resolves your issue or not.
2] Add more virtual processor
Like RAM, it is required to provide your virtual machine with an ample amount of processing power. Having one or two virtual processor cores might not be enough all the time – especially when you are using Windows 11. Therefore, it is better to improve the processing power and check if it solves your issue or not. For that, do the following:
- Open Hyper-V Manager on your computer.
- Right-click on the virtual machine and choose the Settings option.
- Go to the Processor tab.
- Increase the number of virtual processors.
- Click the OK button.
- Restart your virtual machine.
3] Disable Windows Search service
The goal here is to improve your CPU resources by disabling some highly functional services and apps. Windows Search is one of the services that run in the background continuously. Therefore, you can stop this service and check if you get any improvement or not.
- Search for services in the Taskbar search box and click on the result.
- Double-click on the Windows Search setting.
- Click on the Stop button.
- Click the OK button.
Now check if the problem still remains or not.
4] SSD instead of HDD
There are several reasons why you should use Windows with SSD, and when it comes to speed, SSD outranks HDD every time. Therefore, if you have installed your host operating system on HDD, it is better to switch to an SSD. It is possible to migrate your OS from HDD to SSD without losing data or reinstalling the OS.
5] Enable Guest services
Enabling Guest service is handy when it comes to speeding up the Hyper-V virtual machine. By default, Hyper-V doesn’t enable it, and here are the steps to turn it on:
- Right-click on the virtual machine in Hyper-V.
- Select the Settings option.
- Go to the Integration Services tab.
- Tick the Guest services checkbox.
- Click the OK button.
Now, check if you can start the virtual machine quicker than earlier or not.
6] Check hard disk health
If your hard disk has poor health, the perforce will reflect on the Hyper-V virtual machine. Therefore, it is better to check the HDD health using HDD Expert app first. If it shows any error or problem, you have to take the steps accordingly.

Here are answers to some questions you may have.
Why is my virtual machine running so slow?
Several things can make the virtual machine slow on your computer. You can assign at least 1/3 of your RAM, two core virtual processors, etc. On the other hand, don’t forget to check the hard drive health and enable Guest services in Hyper-V.
How much RAM should I give to virtual machine?
It is recommended to provide your Hyper-V virtual machine at least 1/3 of your physical RAM. If you have 16GB of RAM, you should assign at least 5GB to the virtual machine. Whether you install Windows 10 or 11, this calculation doesn’t change significantly.
Does running a virtual machine slow down your computer?
Partially, yes. Running a virtual machine may slow down your host computer because the virtual machine consumes the CPU resources all the time. However, if you can tweak the aforementioned settings, you might not find a very high decrease in performance.
How much slower is a virtual machine?
A virtual machine is always slower as compared to the host computer. In other words, if you provide the same CPU resources to install a virtual machine and install an OS natively, you can find some performance lag in the virtual machine. There is no specific percentage as it depends on the quality of the hardware.
That’s all!
