VNC into Nutanix VM python

Hi there,I hope you all are having a wonderful day!I have a Django application running. I want to integrate a feature which allows users to connect to their specific VM remotely (via VNC). I did find a lot of help related to APIs, but nothing related to something like this. I’d really appreciate if someone can help me out with this one, as I’m absolutely lost here.Thanks in advance.

APC Powershute Network Shutdown - AHV Migrate VMs support

HiWe are currently putting up a new environment with AHV and APC UPSs and thought that the ‘Nutanix Ready’ was suppose to cover all areas of the software from APC. Looking deeper it seems only vmware has the support to migrate VMs over a cluster if UPS power fails on one side. Does anyone know when APC plan on releasing a version that covers this also for Nutanix AHV?ThanksOscar

How to Grant Prism Administrators Access to CVMs through SSH ?

Currently we are working on a project that requires couple of Admins to SSH into a CVM to execute some commands.  The problem we are running into is that only the Nutanix\Admin default account can actually SSH  into CVMs. Other non-default admin accounts (Cluster Admin) can do everything in Prism but are denied access when they try to SSH. Do The non-default admins need additional permissions\configurations to be able to SSH into CVMs ?
