Hi. New to Nutanix for only a month, doing testing as a VMware replacement. One we thing currently do in vCenter is have very granular permissions. Only Linux engineers have access to Linux VM, and Windows engineers to windows. And Linux and Windows templates already have pre-defined category attached. I can build an authorization policy based on the “virtual machine admin” role and apply the scope to only AHV with category of linux and apply it to a linux user. However they cannot seem to build any new VMs, etc. Only manage what current VM has that category. I have tried to all other entity types as full access, but that doesn't seem to work, they can manage both sets of VMs. I am probably doing a terrible job explaining this, but if someone can tell me this can be done and give some hints, I can keep trying. I am certain I must be able to duplicate these permissions we already have.Thank you!

We're currently running low on available storage in our Nutanix environment, and I’d like to ask for your advice on how we can free up space effectively. If there are recommended steps or best practices we should follow, I’d really appreciate your guidance 

When physically configuring the DR center, we plan to set it up through migration. Would it suffice if only the Prism VIP has network connectivity? Or should communication also be established between each node?

Hello community. I am new to Nutanix, we just got a 3-node POC to evaluate a move off of VMware. Regarding Nutanix tools, it appears unlike VMware which the clone from template will keep a functional tools, Nutanix does not work that way. You have to install Nutanix tools after the clone or during the deployment. Is there a good KB or blog on this? We are very well versed in Red Had. We use Ansible and Satellite for our Red Hat management. I found a gzip for the Tools you can install, but how do you get it registered to the cluster? Is there a json file or something that we need to include in our clone that has the cluster ip, etc. Any help to get me started on this is appreciated. I will need to tackle Windows later, but I am not versed in Windows very well.Thank you!
