Using HashiCorp Packer to deploy a VM
Hello! I’m new to the Nutanix community. Loving the tech so far, but... Has anyone used Packer to deploy Windows from within AHV? I’ve seen plenty of how-to’s on how to create a VM image that can be uploaded to AHV. I want to do the entire process within the cluster. Packer has a QEMU builder but not sure how I can tell it to build it on another VM within the cluster. I’m trying to replace my MDT image deployment process with something that can do Windows and Linux and is more RCS/git friendly. I’m not married to Packer so I’ll take suggestions on other possibilities. And if more detail is needed on what I’m doing currently or desired outcome let me know. Thanks in advance!
DR Scenario and stop auto power on VM AHV

I need to power it manually.
Disk layout for Vmware SQL 2016 Guest Cluster
Hello all I'm trying to establish the optimal disk layout for a VMware MS SQL 2016 2 node guest failover cluster that will have a single SQL instance hosting multiple small to medium sized databases. Unfortunately we don't really have the funds for licensing to do the recommended approach of creating lot of small VMs to host these databases, so we need to consolidate where possible. I've been reading though the Nutanix SQL 2016 best practice guide and it's raised a few questions. I've decided to allocate multiple vdisks specifically for database files, so I'd have a few database files to each vdisk instead of one vdisk with all the database files on it. I'm assuming this approach might be better due to each vdisk having a 6GB Oplog allocation and so more vdisks would prevent a single oplog from quickly over filling? Is there any there real a benefit here to having more vdisks to spread the databases across or does this only really come into play when you split indi
Single larger drive or several smaller drives attached to VM?
We are in the process of setting up a new fileserver using AHV and Windows 2019. Our current physical server has one larger 2TB drive letter for all file storage with 3-4 various shares. My question is would it make any difference to keep this same setup with AHV, 2TB drive attached to the VM for storage for files, or would it be better to have 2-3 smaller attached storage drives?
Where's our storage space?
Hi, I just added a new storage disk onto a VM and copied data onto it then realize we'd rather just expand the current one so I deleted the new disk and when I go to expand the current disk it is showing that I have no more space to use to expand. Where is the space going after I delete disks? Thanks,
Foundation and Phoenix
Hi,I have a confusion between the role played by foundation and phoenix, during a LCM firmware upgrade, moreover I am not finding a deep dive article explaining this end to end:1. Once the phoenix iso is created and mounted to the host along with the upgrade bundle, Can phoenix run independently and complete the upgrades or needs help from foundation for performing some tasks like host reboot ?2. During LCM upgrade, since the node undergoing upgrades, will have all VMs powered off including the CVM, will it take help from a remote CVM foundation to orchestrate the upgrades on this host ?3. Putting host in maintenance mode is taken care by LCM or foundation service?4. Can you please give a high level working of the phoenix mechanism, since the hypervisor installer itself is a separate iso, which needs to be mounted, just wondering how phoenix handles multiple iso, does it mount simultaneously with the upgrade iso?
Is Hyper-V Generation 2 UEFI a showstopper for Production VMs?
I’m planning to move a Windows Server 2012 R2 Datacenter Edition VM from Hyper-V 2012 R2 to AHV on AOS 5.10.2 today. I have created a similar (but not cloned) test VM in the environment and migrated it yesterday with no issues. UEFI worked fine. Today in my final prep I’m seeing that in newer versions of the Nutanix documentation (AOS 5+) that this migration and VM type (AHV with UEFI) is listed as Limited Support and “Not recommended for Production”. [b]Is this a showstopper?[/b] Are other customers moving important production Gen 2 UEFI Hyper-V VMs to AHV?

What organizations lose when not chose Nutanix as the Hyper-Converged Infrastructure (HCI) Solution – Part 1
Technology landscape is changing rapidly, and IT teams in organizations should embrace the newer technology at the earliest as it would be refreshed in no time. Meanwhile, there are some technologies which are making their presence felt and getting enough attention that every other vendor is willing to launch or have a me-too product irrespective of its [b]Reliability, Availability, Serviceability,[/b] and[b] Scalability[/b] features. The technology is Hyper-Converged Infrastructure aka HCI. The organization coined and pioneered this is Nutanix Enterprise and a product initially good for running Virtual Desktop Infrastructure (VDI) Solutions has become de-facto standard for all kinds of virtualization workloads be it VDI, Remote Office Branch Office (ROBO), Business Critical Applications (BCA), or similar virtualized workloads. Nutanix is about to complete 10 Years in industry, lot of things have changed from its inception as a Hardware Appliance-based Solution to True Hybrid Cloud bas
AHV Deploying FortiAuthenticator

Running Red Hat Openshift on Nutanix AHV
The technical piece below found our way through our partner channels. Installation instructions for Red Hat OpenShift on Nutanix are detailed in the documentation below. Enjoy, and as always feel free to provide us with feedback. User Provisioned Installation of Red Hat OpenShift 4.3 on Nutanix AHV 5.15 This manual was created during a proof of concept environment using Nutanix AHV 5.15, the KVM-based hypervisor of Nutanix, with OpenShift 4.3 in combination with the Nutanix CSI driver. The Nutanix CSI driver provides scalable, persistent storage for stateful applications using Nutanix Files and Nutanix Volumes. Please note: At the time of writing, Nutanix AHV in combination with OpenShift is supported by Nutanix, but not certified by Red Hat. If certification is required, clients are advised to use any of the other hypervisors supported by Nutanix. The installation steps followed are documented in the IBM Cloud Architecture & Solution Engineering repository guide. The PoC envi
Install NGT on VM template before Sysprep?
Is it ok to install Nutanix Guest Tools in a guest vm template before the template is Sysprepped? I need to deploy a bunch of Server 2008 r2 VMs that will need NGT. I'm aware that it's easy to automate NGT install AFTER vm deployment and I do that for most cases; however on Server 2008 r2 builds there's a techinical limitation that prevents this from working. So I'm wondering if there is anything in NGT that will break if the vm is Sysprepped afterward.
100% CPU Usage on all my hosts
In the last few weeks we have been experiencing complete host CPU usage at 100% on all of our host(6 of them). We were never this high. When the system is at this level no one can do much on the ystem for a few minutes. The biggest change we did was add Bitdefender Gravity Zone to our system. We have about 650 VMs on the system. Memory usage hovers between 50-60% on all the hosts. We are running ESXI hypervisor with VMware Horizon to run our VDI system. Anyone have an insight into this situation? Is there any tweaking I need to do? What could be causing this?
Nutanix space reclaimation
Hi Team, We are running few file servers (windows 2016 machines) which are running on Nutanix + VMware 6.5. For e.g. i have a 5TB VMDK attached to the VM which is holding up a lot of files (being a file server). Now when we check the size of this disk in VMware, we this as around 4TB consumed (similar figures in Prism as well). However within Windows, the actual space consumed is only 1 TB. The question is - how do we reclaim this space to match up the numbers seen by OS with what VMware believes the used space is. (i have seen some posts where users have mentioned using sdelete etc. but it isn’t really a scalable solution) Thoughts ? Thanks. Ravi
SSH Public Key is removed from ESXi
Hi,we are running 20 Nutanix Nodes with AOS 5.0.1 and ESXi 6.0 as hypervisor. Normally we using passwordless login to the ESXi host using SSH Keys. So we copy our public key as usual to /etc/ssh/keys-%u/authorized_keys, but after a reboot of the ESXi Host our keys are removed.So I modified the sshd_config on the ESXi host to use multiple authorized_keys- AuthorizedKeysFile /etc/ssh/keys-%u/authorized_keys+ AuthorizedKeysFile /etc/ssh/keys-%u/authorized_keys /etc/ssh/keys-%u/authorized_keys2But even with this config, the authorized_keys2 is also deleted.Can anyone assist me to solve this issue in case of our internal security guidline to use passwordless login.Best regardsMarkus
Is It Possible to Image the New Node With Version 5.20?
Hello Guys, I have a scenario where the current nutanix environment NX-1065-G7 AOS version is 5.20 LTS and AHV version is 20201105.2030 and we are adding new node NX-1065N-G8 to the cluster. As I referred in documentation that the current nutanix environment version is not compatible with G8. Is it possible to image the new node with version 5.20 ?
Nutanix Node Expansion Queries
Hello Guys, I have a scenario where the current nutanix environment NX-1065-G7 AOS version is 5.20 LTS and AHV version is 20201105.2030 and we are adding new node NX-1065N-G8 to the cluster. My plan is to upgrade foundation and NCC of the cluster to latest version and then image the new node with AOS and AHV version the same as in the current nutanix environment.What are the caution points I need to be aware while configuring the node and adding to the cluster?what are the risk factors involved?
