Hello!
Error code description Service startup failed (usually showing switch driver failure).
Possible reasons - There is a problem with the virtual machine display driver.
- Virtual machine memory exception
Approach - Restart the virtual machine.
- If the problem persists after the restart, log in to the VM (VNC or RDP) and check if there is a problem with the display driver of the VM. Under normal circumstances, the display driver of a normal virtual machine is as follows:

- If the display driver has an exclamation mark or is disabled, fix the display driver (restart enable drive or reinstall HAD software).
- Confirm whether there is a corresponding driver file under the file path.
C:\Windows\System32\huawei_display_driver.dll; C:\Windows\System32\drivers\huawei_display_driver.sys
- If you do not have these two files, the possible reason is that the HDA installation package is not installed successfully; the anti-virus software mistakenly believes that the virus deletes the file. It is recommended to uninstall the HDA installation package before reinstalling.
- Check whether the server and client software version time is very different. If the time varies greatly, it is recommended to update.
