Nutanix Cloud Infrastructure

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!

 Environment AOS Version: 6.8.8 Hypervisor: AHV 2022.10 CVM: Nutanix CVM version 5.18.3 VM Guest OS: Ubuntu 20.04 LTS Storage Type: vDisk attached as AHV data disk DescriptionWhen I create a new vDisk, write data to it, and then delete the vDisk in Prism, the underlying storage space is not reclaimed immediately. I still see the same physical usage reported in Prism Element and on the CVM filesystem, even after: Deleting all snapshots and clones Running fstrim -v /mountpoint inside the VM Executing the Reclaim Space action in Prism Triggering a manual Curator scan (curator_cli scan start) I expect the deleted blocks to be freed right away, but they remain allocated for hours or even days.Steps to Reproduce In Prism Element, create a new 50 GB vDisk and attach it to a running VM. Inside the VM, format and mount the vDisk: mkfs.ext4 /dev/nvme1n1mount /dev/nvme1n1 /mnt/testdisk Write 20 GB of test data copying from windows os disk Unmount and delete the vDisk in Prism.

i have already seen this article, but have many questionshttps://next.nutanix.com/ahv-virtualization-27/is-there-a-way-to-export-prism-central-s-network-flow-data-42446?utm_source=chatgpt.comWhere is a comprehensive KB that explains the requirements, licen, PC components, services and feature that must be in place to enable an ipfix exporter. I am not talking about an extensive api configuration guide, i need the pre-requisites to create an ipfix exporter and the detailed steps to do so.for instance:1-enable microservices2-enable the adv network controller3-change vlan from basic to managed4-configure ipfix exporter through rest api v4 Please dont direct me to my account team for a PS engagement sell… this information should be publicly available.  

Hello !!! Please help me! I found documentation from Nutanix stating that Docker is not supported on Win2016 using AHV, does anyone know of any more recent documentation that informs the version of Windows that is supported on AHV?Does Nutanix support Docker installation on a nested virtualization on AHV?    (version 2024)

Hello again from the research team! We’re trying to better understand how users interact with the 'search' option in Prism Cental, whether you use it, how you use it, and what you think of the search queries with operations. Your feedback will play a big role in helping us design a simpler, more unified search experience. Motion Design & IllustrationsWe’re exploring how visual elements like motion and illustrations can improve clarity, guidance, and overall experience in the product.You can take either survey or both (we’d love that! ). Each one just takes a few minutes, and your feedback helps guide what we build next.  Take the Advanced Search Survey https://ntnx.design/search-survey [Take the Motion & Illustration Survey]https://ntnx.design/animation-surveyThanks for being part of the Nutanix community 

Dear Nutanix team .We need to deploy Cisco Unified Communications Manager and UCCX by Cisco  on Nutanix AHV.Today, it is not possible to run Cisco CUCM and UCCX on Nutanix AHV while also being supported by Cisco.They shared ova file with us, But Cisco  requires VMWARE Esxi virtualization only.In this situation we have not any choice.Could you help us with this case? Maybe you can discuss this issue with Cisco and they will add some solution and support for Nutanix Platform.How can we use this solution by cisco on Nutanix ?

Hello,I used the following GET request to list the VMs :/api/vmm/v4.0/ahv/config/vmsThe return error was PLAT-10006. I investiguated and found that only one VM was the culprit. When I use the previous endpoint with the name filter to pinpoint the VM I indeed get the same error.Finally, the following endpoint with the VM ext-id produces the same error :/api/vmm/v4.0/ahv/config/vms/${vm-ext-id}The same request in the V3 API produces no error. On the UI, the object is visible and looks normal. Even in NCLI the object is correctly fetched.I’m on pc.2024.3.1.1 and AOS 6.10.1.5Does any one know what could cause this ?Does someone know the full meaning of PLAT-10006 ?
