We are saving the password in the user_vm_details explicitly. We are not
checking if ssh key pair is set for this vm or not.
I agree that ideally we should sync the password between the master and
backup, For any kind of sync to work we need to know if the password was read
from one of the VRs and In cases when one of the Vr is Stopped we will have to
clear the password from db when it is read from the other one. These type of
changes add complexity to the simple task of setting a password. The next best
thing is to make sure we save the same password in both the routers. This will
fix will at least solve the problem of sending the correct password even if the
master and backup change state before the VM starts.
Yes like you pointed out this will lead to the problem that the user might
receive the old password when he stop starts the VM, In this case the user will
get a notification in the UI that his password will be changed. So he at least
knows what the password is and so he can log into the VM.
