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!

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?

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

Windows 10 vTPM not recognized by intune

 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!

Error in API Reference - Python on ntnx_vmm_py_client.AssociateVmCategoriesParams()

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

update from AHV el8.nutanix.20230302.103003 to el8.nutanix.20230302.103014

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

slow performance with Citrix MCS

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?

Category on PCVM

It seems to be the case that no category and value can be applied to the PCVMs.Is that true and if so, will that be altered in the future?If not this causes some unexpected challenge. Thank you

Volume Group resilience

We have a couple of VG’s with 20’ish disks in each, on our 4 node AHV (AOS 6.10.1) cluster. 1 VG is shared with 2 SQL boxes in prd and the other with 2 SQL boxes in our pre environment.  I was patching the environment today with a BIOS update so the hosts needed to be restarted for the update to apply, I had a report from our DBA that they lost connection to the shared disks from the SQL boxes.  What is the expect behavior for VGs with shared disks when a host is unavailable due to a planned or unplanned outage?

AHV/ PC snapshot

Hi, Hello,Am looking for help on snapshots and reverting to recovery points. Is my PC GUI fully equipped to handle snapshots and restore to snaps? sometimes for some vms it works and it doesn't for for few other vms. as a workaround we were asked to do it via CLI. though this may get fixed in later versions, any RCA on why this happens? am on AHV 6.x version.Are these snapshots work exactly like the snapshots from VMware or is it different?

non_migratable_vm_action what is the difference between block and acpi_shutdown?

Hi,I am confused by information in the prism central infrastructure guidePrism pc.2024.3.1 - Defining Behaviour for Non-migratable VMs (GPU/CPU/PCI/Host Affinity configured VMs)non_migratable_vm_action: By default, this parameter is set to block, which means the non-migratable VMs are shut down when you put a node into maintenance mode. For more information on non-migratable VMs, see Non-Migratable VMs.If you want to automatically shut down such VMs for the duration of the maintenance mode, set this parameter to acpi_shutdown.It seems both settings result in shutting down the VMs. Am I missing something, or is there an error in the documentation? I assumed block would prevent maintenance mode and keep the VMs running.Same information in the AHV guideAHV 10.0 - Putting a Node into Maintenance Mode using CLI

Storage tiering for QLC SSDs

I am considering building a cluster that will use a mix of TLC and QLC NVMe SSDs. I assume that Nutanix will put all of these drives into the SSD-PCIe storage tier and every disk will be a member of the same tier. Since QLC SSDs have lower performance and lower write endurance than their TLC, MLC, and SLC counterparts, it would be advantageous to use storage tiering to encourage cold data to reside on the QLC media and hotter data to reside on the more performant drives. Is there a supported method for this in non-community edition clusters? It would be relatively straightforward to manually change the tier-name for the QLC drives to SSD-SATA, but is that a supported practice?
