    All required parameters must be populated in order to send to Azure.

    :param os_type: This property allows you to specify the type of the OS
     that is included in the disk if creating a VM from user-image or a
     specialized VHD. <br><br> Possible values are: <br><br> **Windows**
     <br><br> **Linux**. Possible values include: 'Windows', 'Linux'

    :type vhd: ~azure.mgmt.compute.v2018_04_01.models.VirtualHardDisk
    :param image: The source user image virtual hard disk. The virtual hard
     disk will be copied before being attached to the virtual machine. If
     SourceImage is provided, the destination virtual hard drive must not
     exist.

    :param create_option: Required. Specifies how the virtual machine should
     be created.<br><br> Possible values are:<br><br> **Attach** \\u2013 This
     value is used when you are using a specialized disk to create the virtual
     machine.<br><br> **FromImage** \\u2013 This value is used when you are
     using an image to create the virtual machine. If you are using a platform
     image, you also use the imageReference element described above. If you are
