VNC password can't be changed or at least discovered

Hello again, I apologize if I create bugs which I should not but I work as a programmer and I am used to this process. So here is another thing: When I create new KVM machine from some prepared image (Created by Virtualmin) I can set password there and this password is set as VNC password too. The problem is when I create new (empty) machine from some other image, VNC password is random. I can connect to VNC console within Cloudmin without problem, but when I use some other application (for example TightVNC) it requires VNC password. I find out it is in password configuration file as "kvm_vnc_passwd".

I think it would be good to - show this password in "System Details" (and maybe let user change it) - or set it as system owner password (and update it properly when changing owner or owner's password)
