Sheng Yang commented on CLOUDSTACK-4184:
----------------------------------------
It's possible due to the script using in the VM template. Please refer to my
mail for the location of template I used.
Without the guest script, it's hard for me to guess what's wrong. VR seems
doing the thing right, so what we need is tracing down guest script to see why
it didn't received the password.
> VM password reset works inconsistently
