The login credentials being requested on the serial console of your virtual machine refer to the username and password that were set up for the operating system within the VHD (Virtual Hard Disk) image. When you create a VM from a VHD image, it carries over the OS and its settings, including the security credentials needed to access it. You’ll need to enter the correct credentials to gain access to the VM’s operating system. If you’re unsure of the credentials, you may need to check with the person or documentation that provided the VHD image, or consider resetting the password if the system allows it.
