Can I Reserve VM Resources in AHV 10?

I want to reserver as mentioned below for a Linux VM running on AHV 10 and AOS 7.3. CPU: 4 vCPUs with a 10,000 MHz reservation Memory: 10 GB with a 10 GB reservation Disk: 1 x 110 GB with thick provisioning If these reservations exist, how can they be configured? I couldn’t find any information in PE/PC. It also seems that this feature was available up to AOS 6.8 but not in AOS 7.x versions.Let me know if there are any workarounds as well.

Reverse Replication for Faster Failback

Hello, I’m new to Nutanix and setting up DR for VMs on vSphere ESXi.While failover from primary to DR site is straight-forward, I was wondering on the amount of time for failback. Normally, when failback is initiated, it will replicate changed blocks from DR site to primary site.And this may take a while depending on the changes occurred while at DR. Is it possible to do reverse replication while still at DR? This way, when failback is initiated, only the few remaining changed blocks need to be replicated - shortening the failback time.Thanks for your comments

Clean install instead upgrade

HeyI have a 4 node lab with some version. I want to upgrade to the latest version (7.3 right now). my hardware support it. But, instead upgrading, I want clean install (for my reasons).When I using foundation, it won’t discovering my nodes (since they are used).What should I do to make them to be discovered? Thanks.

Replace G5 cluster under vSphere Essentials Plus 7

I have to replace a 3 nodes G5 Nutanix cluster running with vSphere 7 Essentials Plus Edition (limited by design at 3 nodes only) by 3 new nodes.My first idea was to expand existing cluster with new nodes then removed old nodes one by one.But like the vSphere Essential Plus edition is limited to 3 ESXi hosts only i can not add prepared new nodes to my vCenter.🙄 What is the best method in my case to migrate to the new 3 nodes ? Thanks for your advises.Nicolas

Macro for prism central in self-service

HeyIn Calm (Script that I have in old lab, AOS v6.5) My script (part in blueprint) use REST API and ip is used as localhost: Now, In self-Service not accepted localhost (security reasoning).In Self-Service Administration and Operations Guide I see some script that use @@{pc_ip}@@ but this is not real variable.Is there any alternative to get the Prism Central IP and use it in my script? since I use the same script in many PC, It not good practice to hard coded the IP..alternatively: is there a way to get the cluster list (instead use API)? Thanks

Packer Windows 2022 Boot Loop

We are new to Nutanix coming over from vSphere and are experiencing the same issues that is discussed but not resolved on this thread:https://next.nutanix.com/ahv-virtualization-27/packer-press-any-key-to-boot-from-cd-dvd-issue-43213We are using Packer to build a Window 2022 image. We have customised the ISO to remove the "Press any key to boot..." prompt. However, we are now in a situation where Packer/AHV doesn't allow us to specify a boot order so the CD is constantly booting, installing and rebooting.We can continue the Packer build if we manually dismount the CD, however, we want to be in a position where this is a hands off build and orchestrated by a pipeline like our vSphere builds are.Has anyone managed to get around this?

Nutanix replication between two PC during upgrade

I have several asynchronous protection policies configured between two Nutanix clusters each with their respective Prism Central, one primary and one DR. I am going to perform the upgrade of the clusters sequentially on different days and I don't see any reference in the documentation as to whether it is necessary for replication during the upgrade due to version difference or possible outages. I understand that it is not necessary, but I would like to know if there is any good practice as I don't see anything in the documentation. Thanks

Issue with Booting Nutanix Installation on Lenovo HX630 V3 CN Servers

We recently acquired four new Lenovo HX630 V3 CN servers to deploy the latest Nutanix AHV and AOS. Our plan is to set these up on four AHVs and the latest Prism Central. According to the compatibility matrix, this configuration should be supported.I downloaded the latest AHV (AHV-DVD-x86_64-10.0.1-219) from the Nutanix portal and created a bootable USB. However, I encountered an error when attempting to boot into the Nutanix installation process.I understand that I need to use Foundation, but my servers are new and don’t have DiscoveryOS or something similar that would allow me to discover them with Foundation tools. Could you please advise on how to resolve this issue?

Disable proxy ARP within the Nutanix VLAN. What? How?

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!

ESXi vs AHV - Cluster Load Balancing

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

Nutanix Backplane network

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

Do I need to licence the storage available in a S3 bucket configured as a tiering location in Nutanix Files?

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

Deskmini A 300へのNutanix CE2.1インストール時のiSERポートエラーについての相談

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。
