AHV Virtualization

Hello, This question came to mind when i was exporting  a VM . Where the OVA file is actually stored?because i didn’t get to choose the storage container where the OVA file will exported to?

Hello all, I've come across an issue when attempting to create a VM via Prism central i get a fetch error below. Nonetheless i haven't found much on the issue and am turning to see if anyone has any insight. 

Hi all,I have a nested environment with a three-node cluster and also a one-node cluster with AOS 7.3.0.7 and AHV 10.0.1.1. When I tried to update AHV to any available version, the upgrade failed. Does anyone have advice to find a solution or experience with this issue?Thanks

HiI was trying to deploy a single node AHV cluster on a HPE host. As previous task I’ve applied the latest Service Pack for Proliant and I’ve updated the ILO6 to the latest version 1.72 and configure the static network on ILO. Then I uploaded the AOS 7.3.1 and AHV 10.3.1.11 (latest releases) to the Foundation (windows app) and I’ve launched the deployment wizzard.The foundation process started but it crashed at 41% with the following errors: 2025-11-27 13:19:11,970Z imaging_step.py:123 DEBUG Setting state of <ImagingStepValidation(<NodeConfig(139.128.156.70) @ff10>) @f7c0> from PENDING to RUNNING2025-11-27 13:19:11,974Z imaging_step.py:159 INFO Running <ImagingStepValidation(<NodeConfig(139.128.156.70) @ff10>) @f7c0>2025-11-27 13:19:11,978Z cache_manager.py:133 DEBUG Cache MISS: key(common_validations_()_{'global_config': <foundation.config_manager.GlobalConfig object

Hi Community,Is there any best practice or guideline I can follow for naming VMs in Nutanix? For example, are there any restrictions on which characters can be used?

Hi. I am new to Nutanix. Our first cluster was pre-configured. We use two internal NTP appliances at the time, and we just purchsed a third. I was logging in to configure it and noticed some oddities.It appears first that I had to set add the new NTP server both to prism central and element. After I added it to Element this command on a CVM was accurate “ncli cluster get-ntp-servers” However the AHV hosts do not appear to get this new server from either prism central or element.  “sudo chronyc -n sources -v” confirmed the original 2 ntp servers were the only ones configured. I added the third and restarted chronyd and it showed up now and is syncing however moving on to the 2nd and 3rd AHV host, the chrony conf is much different. It has the ntp server as the first ntp host? Was this a mistake on part of the installer? I would assyme it should have the exact chroyd.thank you for any clarificaiton.

Hi Folks,am updating my script for creating a snapshot and store in file device am currently using V3 prism central APIs and want to migrate to use V4 APIS. someone help me with the sample response of APIS in V3 and V4 for List VMS.V4: https://{pc-ip}:9440/api/vmm/v4.1/ahv/config/vmsV2 prism element:  $CLUSTER/PrismGateway/services/rest/v2.0/vms → am using this currently. any dummy VM response is fine just want to estimate the changes and complexity.

Hi Everyone, Just throwing this out there and was wondering how others have experienced this.We use VEEAM as our backup solution and were having some issues trying to move from ESXI to AHV. Every time we started a move using Nutanix Move we’d have an error about CBT not being enabled. Our resolution? Disabling CBT (yes disabling not enabling) using the following PowerCLI script!After we ran the script the move completes succesfully! (Make sure to run it before creating your migration plan)No clue if anyone has the same issues as us but if you do this might be a solution!Import-Module VCF.PowerCLIConnect-VIServer -Server YOUR.VCSA.SERVER$vm="YOUR.VM.NAME"$vmtest = Get-vm $vm| get-view$vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec$vmConfigSpec.changeTrackingEnabled = $false$vmtest.reconfigVM($vmConfigSpec) Regards,West

Hello Team,While deploying the cluster using Foundation Tool, is there any way to provide pre-reserved CVM names anywhere before initiating the cluster build process through this tool?If not, how can change the name of CVM (inside OS) after cluster got built? How much risky is this process? You feedback/help in this matter will be highly appreciated. -Anil 

Hi, we are new Nutanix customers coming from VMWare. I’ve migrated about 450 VM’s over and everything is going smoothly, however when it comes to Linux appliances I have some questions. On VMWare, vendors would send us an OVA which included VMWare tools baked into the appliance. I’m noticing that vendors who supply QCOW2’s, or even OVA’s if they don’t have a QCOW2 file, don’t have NGT baked into the image. When I ask the vendor how to install NGT, they say it’s not supported, even though on VMWare, they had VMWare tools supported.Is it typical for vendor linux appliances to not support NGT? How do I get VSS working on these appliances with NGT so that my backup solution can take app-consistent snapshots? Also, I hate looking in PC and seeing VM’s without any OS because NGT isn’t installed.

Hello, I have installed a 2 Node cluster using nutanix foundation VM with witness node as a tie breaker in dell xc4510 and everything is running fine. I have created multiple production VM. I have an another host with same hardware configuration and want to convert 2 node to 3 node cluster. I want to know the best procedure to achieve this.

HiAs you know Windows server 2003 is not officialy supported with AHV or MOVE but using the following link I was able to migrate a VM with Windows Server 2003 from an old vCenter to a new AHV cluster. https://www.vmwaremine.com/2019/01/24/migrate-windows-2003-x86-to-nutanix-ahv/#sthash.8hpeCflP.T3i44mTW.dpbsThat being said, after migrating it thw VM works fine but I have a question regarding VMware tools and Nutanix Guest tools. 1. Is it mandatory to remove the VMware tools from the migrated VM or is it just a “aesthetic” matter?2. Is it mandaroty to install Nutanix Guest Tools? I mention this cause I wasnt able do to this error when loading the NGT CDROM ISO:​​​ 

Hi,I have a customer with a standalone ESXi host running a few VMs. All backups are currently performed using Acronis Backup.I need to replace this ESXi host with a new Nutanix AHV standalone cluster, and I'm concerned about Acronis compatibility with AHV.As far as I know, Acronis requires an agent to be installed inside each VM that needs to be backed up. If I migrate these VMs from ESXi to AHV, will this affect Acronis Backup in any way? Is there any incompatibility between Acronis and Nutanix AHV?When checking the Nutanix Compatibility Matrix and the Acronis documentation, I see that the Nutanix “Data Protector” option is only supported on AHV versions 6.8.1 and earlier.However, I’m not sure whether “Data Protector” is required at all for Acronis to back up VMs running on AHV, considering that Acronis uses in-guest agents.Here is the Acronis documentation for reference: 

HiI have a customer with two VMware clusters, each one located in a different site (two separate buildings). I need to replace both environments with two Nutanix AHV clusters configured with Metro Availability (active-active).As part of the project, I must migrate the VMs from both VMware vCenters to the new AHV clusters using Nutanix MOVE. The AHV clusters have been sized so that either cluster can host the full workload, so the migration order is not a problem.However, physical rack space is an issue: Site A has enough rack space to install the new Nutanix nodes. Site B does not have space until the old VMware hosts are removed. Because of that, I’m considering different ways to sequence the work, and I’m not sure which approach is better.From what I understand, I should be able to enable Metro A

Hello evb,in a 3-host Nutanix Cluster (AOS 6.10,1 and AHV v.20230302.103003) I have one of the 3 hosts with the [/var] filled up at 92% (2.5GB on 2.9GB)The cluster is up’n’running and was OK until this warning raised by the ncc checks (v 5.1.0)Most of the space is used by:6565632 /var/log4502260 /var/log/sa2546588 /var/lib2406748 /var/lib/puppet2406072 /var/lib/puppet/reports2241772 /var/lib/puppet/reports/HOSTNAMEIn the last dir I have more than 90K [.YAML] files (of about 20KB each and created every 2 or 3 minutes, starting from the first host setup), while in the other 2 hosts I have only 14 [.yaml] files.File names are in the form yyyymmddhhmm.yamlWhat are they used for?Is it safe to delete the oldest ones?TIAPaolo 

I have a 3 node cluster running 7.3.1 and while updating LCM complained that it cannot update NICs but I need to do manually listing KB-10634. I downloaded the x722 0x800042eb update file, executed and failed at the last minute and after the update both NICs are disappeared. I spoke with Supermicro and they are not willing to do anything because the motherboard serial is more than 5 years old and OOW. But one of the Tech advised me to program this chip (AT45DB041E-SSHN) with the 722M4B.bin file at my own risk and discretion, which I did, but nothing changed. nvmupdate64e just cannot see/find these two NICs.So what I tried next was to copy the above chip content from the second good known server and programmed the corrupted chip, but still nothing changed. The good new is that I can still install and use the latest AOS with a PCIE add on X55

Hello everyone, I have a problem with my new created 4-nodes AHV cluster. in my prism element I can no longer see the two nodes ( disconnected), and the default vswitch (vs0) are gone too and can’t recreat it.

HiWhen I start a VM on my Nutanix server I never get display output. Why is that the case or what am I doing wrong?

HiI've deployed a Nutanix Cluster AHV in a dark site. Im having the issue exactly described here:https://next.nutanix.com/installation-configuration-23/prism-central-stuck-at-76-vm-is-not-reachable-42437?tid=42437&fid=23 But the topic was closed without any solution so I have to search for it… In summary:After deploying the cluster I tried to deploy the Prism Central with no luck, it got stucked at 76%... AOS 7.3.1 + PC 7.3.1 The PC VM intially startas and answer by ping, however it is automaticaly restarted during the config process and it loses the net config so it gets unaccesible by lan When checking the Prism Element tasks, I see the Application Deployment task stuck atl

I would like to attempt PCIe passthrough of a QLogic 2662 Fiber HBA to my Windows Server 2025 Nutanix Virtual Machine so that the device shows up in device manager, but I am unable to find clear documentation on PCIe passthrough.

I am trying to create windows 11 on AOS 6.5.1 with AHV 20230302.101026 but failing with this error.  

In the link below I read:"AHV lets you configure vCPUs (equivalent to CPU sockets) and cores per vCPU (equivalent to CPU cores) for each VM. We recommend first increasing the number of vCPUs when a VM needs more than one CPU, rather than increasing the cores per vCPU. For example, if a guest VM requires four CPUs, use four vCPUs with one core per vCPU."From my own experience, performance tests, and NUMA recommendations, I know that you should usually increase cores per CPU first. When you reach the physical cores per socket, then add a second socket.Can someone familiar with the deep architecture of AHV explain why we see that recommendation? I do not believe that an 8-vCPU VM configured as 2 sockets with 4 cores each will perform better than 1 socket with 8 cores.
