AHV Virtualization

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.  

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.

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?  

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!

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 ?

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 

Hii don’t know where to report this(no feedback menu on Redocly), but since people may encounter this issue too, i guess they may land here while searching for a solution.As of 11 April 2025, there is an error in the documentation of APIv4 (python version) with regard to associating categories to a VM.The page is here: https://developers.nutanix.com/api-reference?namespace=vmm&version=v4.0The example code says at one line: associateVmCategoriesParams = ntnx_vmm_py_client.AssociateVmCategoriesParams()well, upon investigating the ntnx_vmm_py_client libraries, i’ve noticed that the class AssociateVmCategoriesParams is imported using AS, therefore with different names depending on technology, as follows: from ntnx_vmm_py_client.models.vmm.v4.ahv.config.AssociateVmCategoriesParams import AssociateVmCategoriesParams as AhvConfigAssociateVmCategoriesParamsfrom ntnx_vmm_py_client.models.vmm.v4.ahv.config.DisassociateVmCategoriesParams import DisassociateVmCategoriesParams as AhvConfigDisas

migration de vm vers nutanix 

has anyone else seen this issue?  We have a Azure NC2 cluster (not in prd yet) and have been notified that we could face the following issueWe would like to inform you about a recently discovered issue where inconsistent CPU microcode configuration will affect the ability to live migrate VMs (internally tracked as ENG-723026). This arises when a Nutanix cluster is upgraded to AHV versions 20230302.103003, 20230302.102005, 10.0.0.1, or 10.0, followed by cluster expansion or node replacement. In such cases, live migration of newly created VMs will encounter issues. Our records show that your Nutanix Cloud Cluster is susceptible to this inconsistent CPU microcode configuration. For details on the action, you can take to remediate, please refer to this Knowledge Base Article. If you have any questions or require assistance, please feel free to open a support ticket.   Anyway I planned on doing the  upgrade to the fixed version in the AHV 20230302 track el8.nutanix.20230302.103014 with the

Hi, we have a new Nutanix Cluster with three nodes. Now we will move our citrix farm from VMware to Nutanix.But on Nutanix the VMs much slower as on VMware. We use publish desktops with Citrix MCS an Fslogix.Login with VMware takes 15 seconds with Nutanix more that 50 seconds.The Nutanix Hardware much better then on Vmware.So we don‘t understand why it is so much slower.Also we use the Best Practice Guide from Nutanix for Citrix MCS.so have anybody an idea, why Citrix is slower on Nutanix and what we can do to speed up the system? 

we need  plan for deploy Stretched cluster with Cisco hyperflex C220 M6 Rack server with Nutanix AOS and vmware ESXi

How can I set a UEFI default resolution using the API to create a vm?
