Hi,“Disable proxy ARP within the Nutanix VLAN before configuring network segmentation” is mentioned in two documents.Security GuidePhysical Networking Best PracticesCould someone clarify what this means exactly?What is “the Nutanix VLAN”? Is it the “CVM/HOST management VLAN or all VLANs? What is the command to disable proxy ARP? Should this be done at the Nutanix level or the physical switch level?I couldn't find answers in the documentation. Any help would be greatly appreciated!Thanks in advance!

Hey all,  I am trying to do a Hypervisor Cluster comparison between AHV and ESXi.  To kick this off, does AHV have a way to load balance the VM’s and move the load to other hosts / nodes with less usage as DRS does for ESXi?  Thanks 

Does the Nutanix Backplane network allow communication between nodes without routing ? I see the CVM’s communicate between the 192.168.5.x subnet, do the CVM’s communicate over L2 within the subnet or do they use L3 in the Nutanix internal network and if I were to disconnect the L1 Physical networking would the CVM’s still be able to communicate over this network ? I am running ESXi ontop of 4 nodes and just trying to establish if the external Physical network impacts the CVM’s on each node / esxi host, if we lost a HBA / physical adapter on that has the Backplane network would the cluster become degraded and would that CVM be offline or would it still be able to talk to the other CVM’s?  Thanks 

Dear community, This is my 1st post/question here.We are storing raw data on one of our Nutanix Files. For the moment, 100 TiB are licensed on for it but these data are increasing quickly. These are mainly raw data that we need to store for at least 5 years. We also need to be able to access these files without any delay if needed in production.Therefore, we are looking for a way to free up space on Nutanix Files using tiering to be able to store these “cold” data in an S3 bucket with a tiering policy (after 1 year without access/modification, the data will be tiered on S3). This S3 bucket is for example 300Tib big.My question here is: we licenced 100Tib of this Nutanix Files with a NUS Pro licence. Do we also need to licence the 300Tib of storage used as a tiering location? Thanks for your helpLionel

Hey I’m trying to install a new cluster with 8 nodes, but on the Nodes fane in Nutanix Foundation I can only choose A,B,C and D.How do I select the remaining 4 hosts? Using Nutanix Foundation v5.7.1 on Windows /Mads

Hi All ,Greetings !!! Single node cluster run very good and works like charm .Now i wanted to create an 3 node cluster . LAB Environment: Host Hardware Specs: CPU: Logical Processors: 24 Processor: Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz Sockets: 2 Cores per Socket: 6 Hyperthreading: Enabled Memory: 159.94 GB Hypervisor: VMware vSphere ESXi-8.0U3e-24677879-standard(Free Edition) Setup: 3-node cluster with Nutanix Community Edition vSwitch Configuration (on all ESXi hosts): Port Group > Security Settings: Promiscuous Mode: Accept MAC Address Changes: Accept Forged Transmits: Accept VM Configuration (per node): CPU: 8 vCPUs (Hardware Virtualization Enabled) Memory: 36 GB Disks: Disk 1: 128 GB (Thin) Disk 2: 500 GB (Thin) Disk 3: 800 GB (Thin) SCSI Controller: VMware Paravirtual Boot Options: Changed from UEFI to BIOS Advanced VM Configuration: disk.EnableUUID = TRUE IP Configuration:Node AHV IP CVM IP 1 192

I installed a single nutanix CE node in a nested VMware VM but the CVM doesnt start.The nested VM Option was checked when configuring the VM and the disk.EnableUUID parameter was set to TRUE. Allocated virtual Hardware: 10cores; 52GB RAM; 16+200+500GB drivesThe installation was successfull, however the CVM wont start with the following errormessage:error: internal error: qemu unexpectedly closed the monitor: 2025-04-29T07:57:29.088493Z qemu-kvm: unable to map backing store for guest RAM: Cannot allocate memoryThe xmldump shows the following:<domain type='kvm'>  <name>NTNX-be7cea29-A-CVM</name>  <uuid>26b6df8b-f03e-482e-b12c-a8e76e767bc1</uuid>  <memory unit='KiB'>16777216</memory>  <currentMemory unit='KiB'>16777216</currentMemory>  <memoryBacking>    <hugepages/>    <nosharepages/>  </memoryBacking>  <vcpu placement='static' cpuset='0-4'>4</vcpu>  <resource>    <partition>/machine<

We should type ‘I Agree’ when shutting down a cluster, so if is it possible to shutdown a cluster with script, or any method to bypass the manual confirmation?

I am curious why the running “ovs-vsctl show” on a AHV host does not show any “bond” whereas the “ovsdb-client dump | grep -i lacp” command and the Prism GUI show lacp is present (the switch too)?Here is the GUI viewfull “ovs-vsctl show” output from AHV host:[root@NTNX-895b5886-A ~]# ovs-vsctl show84a00041-1b46-44f0-99a1-01a0b1a66713    Bridge br.mx        Port br.mx.u.br1            Interface br.mx.u.br1                type: patch                options: {peer=br1.local.d}        Port br.mx.u.br2            Interface br.mx.u.br2                type: patch                options: {peer=br2.local.d}        Port br.mx.u.br0            Interface br.mx.u.br0                type: patch                options: {peer=br0.local.d}        Port br.mx            Interface br.mx                type: internal        Port br.mx.d            Interface br.mx.d                type: patch                options: {peer=br.microseg.u}    Bridge br.dmx        Port br.dmx            Interface br.dmx       

以前に同じ質問をさせていただいたのですが、その後自身で様々な方法を確認しても自体が好転せず他に方法がなくなってしまったため、同じ内容の質問とはなってしまいますが、改めて質問をさせていただきます。 以前の質問の通り、Deskmini A 300にNutanix CE2.1をインストールすると、 setup_rdma.py[8310]: INFO:rdma:No Ports reserved for iSER on the node. Exiting! と表示されてしまい動作が停止してしまいます。これはDeskmini A 300に起因する問題なのでしょうか?あるいは他に修復方法があるのでしょうか?参考までに、Proxmox等の他の仮想マシンは動作を確認する事ができました。 以下、以前の質問文です。現在、Deskmini A 300を使用してNutanix のCE2.1版をインストールしようとしています。 インストール自体は完了するのですが、その後再起動すると     setup_rdma.py[8310]: INFO:rdma:No Ports reserved for iSER on the node. Exiting! という表示が出て、CVMにアクセスする事ができません。そもそもPing自体も失敗してしまいました。(AHVはPing可能でした) 調べてみたのですが、情報が全くヒットしなかったため、めずらしい問題が発生してしまったと考え、こちらに相談をさせていただきました。 どなたか、同じような症状が発生した方や解決できた方はいらっしゃるでしょうか。 マシン構成の詳細は、CPU:AMD Ryzen5 2400Gメモリ:corsair VENGEANCE(DDR4-2666) 16GB * 2枚 ストレージ    CVM Samsung SSD 970 EVO Plus 500GB    ハイパーバイザ WestanDigital Blue SA510 250GB    データ TOSHIBA MQ04ABD20    (データ WestanDigital EAAZ-00BXBB0)(USB外付けHDDのため動作確認のため使用停止中) となり、残りの構成は、DeskMini A300の初期構成のままとなっています。 

How to get Nutanix AHV software's(NOT CE) and trail licenses?

Can I please get the Community Roll. I am trying to get going on my Nutanix cluster and I get this error.   

When configuring a protection policy for synchronous replication between two Nutanix on-premises availability zones (AZs) without utilizing a witness VM, under the Failure Detection Mode setting, in what scenarios should Manual Mode be used, and when is Automatic Mode recommended and that related to witness service?  

In my struggle to find some environment to practice/test Nutanix admin stuff, I’ve now come to Nutanix Foundation (NCE 2.0 worked but is old, NCE 2.1 failed on some networking issue in my environment).Is it possible to create a small single node cluster running as a VM in VMware Workstation using for example Foundation?I made a few tries but it seemed Foundation required IPMI access to the host, but VMs in VMware don’t have IPMI (to my knowledge).  It thought maybe a new VM could be recognized by Foundation (tried both the Windows version and the VM) if it had booted DiscoveryOS, but I couldn’t find the Discovery OS image anywhere…Is there a way forward for an installation like this or is it a dead end?

現在NFR版でノード4つのクラスタを１つ構築しており、バックアップ用にSNRTのノード１つを使用しております。ノードは全てNX-1175S-G8で全部で５台あります。社内で動作検証中のクラスタに格納された仮想マシンが、オールフラッシュノードの容量を超えてしまう事が判明したため、クラスタをオールフラッシュノードから、ハイブリッドノードへ組み換えを行う想定をし、ストレージ用のHDDを購入いたしました。まず、バックアップ用のSNRTのノードを先にハイブリッドノード化し、非同期レプリケーションを用い、クラスタ内部の仮想マシンのスナップショットを取得しております。これ以外で、クラスタ内の仮想マシンを物理的に退避することをお勧めされておりますが、どういった手法が考えられますでしょうか。どなたか手法をご教示ねがえませんでしょうか。

Hello Nutanix Community,I'm trying to install Nutanix Community Edition (CE), but I'm encountering an InstallerVM timeout issue. The installation keeps retrying, and the hypervisor setup does not complete successfully.My hardware setup:1 HDD (480GB) → Intended for data storage. 1 SSD (2.8TB) → Assigned to CVM storage. 1 USB Drive (32GB) → Used for the hypervisor installation.Issue Description:The installation starts but gets stuck with repeated messages: INFO Hypervisor installation in progress INFO InstallerVM timeout occurred, current retry 0 I have already disabled RAID and set the SATA mode to AHCI in the BIOS. The disks are correctly recognized when using lsblk and fdisk -l. I tried wiping the disks (wipefs -a and dd if=/dev/zero), but the issue persists.Troubleshooting Attempts:Checked system RAM → I have more than 32GB available. USB Boot Media → I recreated the bootable USB with a fresh Nutanix CE ISO.

I checked the log rotation interval for CVM and Prism Central in the manual, but I couldn't find any information.With the default settings, how often are logs rotated, and how many generations of data are retained?

If I have two AHV clusters distributed across a primary site and a disaster recovery (DR) site, and I configure Metro Availability between them, is it possible to deploy the Witness VM at the DR site?

I have 2 AHV clusters (3 nodes), and if I want to configure synchronous replication between them, I have two options: Sync Replication and Metro Availability. I would like to understand the key differences between these two approaches and the specific features. Note that I will not use a Witness VM.

おつかれさまです。Nutanixのネットワーク設計に関して確認させてください。Nutanix 1ノードに10G Dual-Port NICを２枚搭載する予定です。合計4つの10Gポートを２ポートずつBondingし、管理系、サービス系で通信を分けようと思うのですがその際にNICを跨いでBondingすることは可能でしょうか？ 仮想スイッチを２つ用意して各スイッチのアップリンクポートとして各NICから1ポートずつ選びBonding設定すれば可能だと思っているのですが、試せる環境がないため確認した次第です。お手数ですがご回答いただけますと幸いです。よろしくお願いいたします。

Issue: I can’t get UEFI to work with VMs at all.CE version of AHV  on Dell 4 year old hardware - AHV and CVM operational and appear fine.VMs appear to be OK as long as it’s using legacy bios. I can’t get UEFI to boot, black screen of X/f2.I was going to attempt a workaround: Install using legacy and convert to UEFI but I can’t get into the VM bios?  Tried F2, DEL, F12 … every F out there and it goes straight to windows.Does anyone have a recommendation? I can take screenshots if that helps 

Nutanix introduces the Multicloud Snapshot Technology (MST) Disaster Recovery (DR) with Zero Compute Deployment as a cost-effective approach to disaster recovery. This solution leverages AWS S3 buckets or Nutanix Objects for storing snapshots, enabling organizations to replicate data from on-premises clusters to low-cost object storage. In the event of a disaster, an on-demand Nutanix cluster can be deployed in AWS or on-premises for recovery, ensuring minimal downtime and reduced operational costs. This article focuses on the MST DR with Zero Compute Deployment feature, its benefits, and how to configure it using a limited access policy for an S3 bucket named zerocompute. Key Features of MST DR with Zero Compute Deployment Cost-Effective Storage: Snapshots are replicated directly to AWS S3 or Nutanix Objects, eliminating the need for perpetual compute nodes. This reduces the total cost of ownership (TCO) by leveraging low-cost object storage. On-Demand Cluster Deployment: In the eve

Hi Friends, I have 3 x Dell XC blocks which are almost 7-8 years and we have plans to migrate them to XC 660 x 3 blocks.Hypervisors running on VMware. Nutanix starter license.May I know what are the procedures on migration? Heard from reddit folks that is to update existing cluster to latest Nutanix software. Then add the new blocks into the existing cluster. Then let it replication and once ok, slowly remove the older blocks. Then move the VMs to start on the new hypervisors? Thanks
