Installing Windows Server 2019 from a remotely mounted ISO

[阿桂]

That is kernel not support udf type ISO，maybe you can use software "UltraISO"  change  udf ISO to cdfs ISO, or modify you kernel source to support udf type ISO。
So, I modify local kernel source to support udf type ISO.
By the way jsnbd's state also need to change  "echo 1 > functions/mass_storage.usb0/lun.0/cdrom"
