Hi, any leads on this please?

[davidt99]

Remove the boot diagnostics option, there is no point to add enable: no.

[Fred-sun]

@Akasurde Thank you very much for submitting this problem. We will investigate. Until the problem is fixed, if you want to create boot_diagno=no, you can create the VM without specifying boot_, which defaults to False. Thank you very much!
