Nutanix Cloud Infrastructure

Hello.I have a question.Resource Requirements Supporting Snapshot Frequency (Asynchronous, NearSync, and Metro) I'm inquiring because I don't understand well even if I look at the link above.Three G9 nodesI'm thinking of making three G7 nodes into one cluster.The G9 node already has a cluster configured and will expand the G7 node.The G9 node is two SSDs and four HDD hybrid HCI.G7 nodes are also six SSD All Flash nodes.G9 Node Disk CapacitySSD = 3.06TibHDD = 6.9qTibG7 Node Disk CapacitySSD = 1.92TibDR is configured in the G9 cluster that is already configured, and snapshots are being taken every two hours and sent to DR. The number of snapshots stored is two.When configuring these services, how much CVM memory should be allocated?The reason for putting the inquiry is that I set the CVM memory to 32GB with G9 initial configuration. It's been about 3 months since the configuration. CVM memory usage is over 90%.We would like to ask for your opinion as the usage increases until a memory us

Je sollicite votre aide concernant un problème sur mon cluster Nutanix de 7 nœuds. Une des CVM a crashé et malgré plusieurs tentatives de récupération, je n’ai pas pu la restaurer. Est-il possible de réinstaller une nouvelle CVM sur ce nœud sans impacter le fonctionnement du cluster?

Hi,I need some clarification regarding the following scenario:We have an on-premises infrastructure running on Nutanix with AHV as the hypervisor. Our goal is to replicate these virtual machines to Microsoft Azure to establish a disaster recovery (DR) setup.Is Nutanix AHV fully supported for replication to Azure in the same way that VMware or Hyper-V environments are supported by Azure Site Recovery (ASR)?Could you please help clarify the possible options, associated challenges, and the feasibility of replicating Nutanix AHV workloads to Azure—particularly through ASR or any alternative solutions? I’m looking for clear insights and confirmation on the best approach for this use case.Thank you.

Hi all, I recently performed a fresh installation of a Nutanix cluster using three nodes, all based on the HPE ProLiant DX380 Gen11 12LFF platform.As part of the pre-deployment steps, prior to imaging the nodes using Foundation VM (foundation version was 5.7.1), I upgraded the firmware on all three servers to Service Pack for ProLiant (SPP) version 2025.05.00.00. This firmware version was explicitly referenced in the Nutanix installation prerequisites and compatibility documentation for this hardware generation.The SPP upgrade was completed successfully via iLO on all nodes, and I validated the firmware version through the iLO web interface post-upgrade.Following the firmware upgrade, I proceeded with the node imaging using Foundation and successfully deployed the cluster without any issues. Once the cluster was operational, I launched LCM > Inventory and ran Perform Inventory to validate component versions.However, LCM still reports the installed SPP version across all hosts as 202

I noticed that Nutanix REST API v3 offer ability to interact with Nutanix Projects. The same features seem not to be available using the new API v4 so far. Will this come in the future? Is there a roadmap with all the features that will be coming in API v4?

We have a 6-node Nutanix cluster on VMware ESXi spread across two racks. Each rack has a ToR switch, and both ToRs are in an IRF stack. All nodes are dual-uplinked (one NIC to each ToR).Core switch handles L3 routing, and VLANs are trunked to the IRF stack.We're planning to replace both ToR switches with new IRF switches — without downtime.Can the community please guide on: Best practices for live switch replacement How to ensure CVM and ESXi connectivity during the change Key health checks from Prism Any Nutanix KB or doc on this

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

Hey all!  I did a cluster conversion and Enabled and installed NGT’s on my guest vms and the vm’s will not boot.    I get the error “Unable to find a valid boot device”   The VM’s are UEFI enabled as well.  

Recommendations for DR Configuration between On-Prem AZsRecommendation for Virtual Networks• Recovery plans do not support overlapping subnets in a network-mapping configuration. Do not create virtual networks that have the same name or overlapping IP address ranges.Quotes from Nutanix Disaster Recovery Guide I would like to clarify the meaning of the recommendation point (Recovery plans do not support overlapping subnets. / Do not create networks that have the same name or overlapping IP address ranges.). Kindly, provide a simple example for clarification, if necessary.

Good day.I transferred the node to maintenance mode via the prism element console, but during the migration of virtual machines an error occurred and the transfer to maintenance mode stopped.At the same time, in the prism element, the host remained in maintenance mode.When checking via the CLI on the central computer, the host is not in maintenance mode, it is also transferred to maintenance mode without errors by the command: acli host.enter_maintenance_mode and is displayed by the command acli host.exit _maintenance_mode.In Prizm Central, the host is also visible normally without maintenance mode.Please tell me, maybe someone has encountered such a problem, it looks very similar to a bug in prism element itself.The command ncli host edit id=7 enable-maintenance-mode=false did not help to solve the problem.When trying to take the host out of maintenance mode in the Prizm Element web console, an error appears that the host was transferred to maintenance mode via the CLI.

how do we go about giving VM’s in our NC2 cluster running in azure pubic IP address? We have a number of VM’s that we need to build that will either require a public IP or be publicly accessible via LB’s running on the cluster (Not native AOS LB’s)  how do we assign a public IP from the Azure public IP address ranges to our VM’s running on NC2?

Hello everyone !I have lost the entire administrator access to my Nutanix CE infrastructure exepted to AHV. I cannot log to my CVM by SSH and cannot log to the web interface of Prism Element ( Account locked due to too many failed attempts.). I also do not have backup account, only the admin one with wich I’m trying to log.I have access to the IPMI of my server and can log to AHV on it, if someone has any idea how i can regain control I would deeply appreciate itThanks in advance

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?  

Hi,Is there a way to query which cluster that a VM is running on from within the VM itself?   I will need this for both Windows and Linux VMs. The reason is I want to take different actions in the Data Protecion Recovery Plan scripts production_vm_recovery and test_vm_recovery depending on which cluster the VMs failed over to.  Thanks,Howard 

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

Hi everyone,I want to upgrade my Prism Central (current version: 2024.2) to a newer version, but I must have a plan to rollback, if something happens along the way. When upgrading using LCM everything seems straightforward and easy, when the checks are done and everything, but are there any risks/losses/possible damages? Can I go back to a previous version? Is there something specific to look out for? What to do if something breaks? Thanks in advance :) 

Hi Team,Is it any possibilities the particular VM disks can able to change it like VM name. 

We’re about to start migrating our native Azure workloads to a cluster running in NC2 in Azure.  On our onprem cluster we use our own DHCP servers for IP management but obviously in NC2 we have to use the built in AHV IPAM.  How can we find what IP addresses are being allocated and to what VM’s?  I thought that this article would help but its not what we see in our NC2 environment.  I can see a summary page in PC which lists how many IP’s are in the pool and how many are in use but there’s no detail about what VM has what address. https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v6_10:wc-network-verify-ipam-ippool-wc-t.html Am I missing something or is it a limitation of NC2?

I can not ping or connect to CVM | Nutanix Community I'm facing exactly the same problem.AHV - CVM  ping yeshost - AHV  ping yeshost  - cvm ping no CVM-AHV ping yes ,  CVM ping the local network no ….  

Dear Team, We have encountered an issue with the cluster, where it is showing a license violation warning. This may impact the stability or functionality of the services running on the cluster, so we would like to request your assistance in resolving this as soon as possible. Could you please check the license details, validate compliance, and help us fix the violation? If there are any specific actions or information needed from our side, kindly let us know. Looking forward to your support on this.

Hello,I have an issue with one CVM after a restart.Could you help me resolve it?

 Hello,We're encountering an issue related to TPM on our AHV devices. While looking for solutions, I found a similar case, but the resolution there was related to the processor rather than TPM.We're trying to perform a feature upgrade from Windows 10 to Windows 11 through Intune, and this issue is blocking the process.Has anyone experienced this problem and found a solution?Thanks!
