A. This is a known problem. A workaround is to change the start behavior of the service STORVSC from 3 to 0, which means the service will be started by the kernel loader.
- Start the registry editor (regedit.exe).
- Move to HKLM\SYSTEM\CurrentControlSet\Services\storvsc.
- Change Start value from 3 to 0 and click OK.
- Reboot the VM.
