AHV Virtualization

HiImagine you have two AHV clusters that are Active-Active (each site has live VMs on it). They are both connected and they are doing Metro-Sync between them.Now you want to move some VMs from one site to the second site. As far as I know I could perform that migration by using MOVE or by doing a manual failover of a protection policy. Is there any way to do a “live migration” between clusters without shuting down any VM?Also, is there any way to do that even if you have Async migration?I have found this but I understand is only talking about migration between nodes): https://portal.nutanix.com/page/documents/solutions/details?targetId=BP-2029-AHV:nutanix-ahv-live-migration.htmlThanks

Hi Guy’s I'm trying to update our Dev environment which runs on community edition, and AOS, NCC etc all working via LCM, for the AHV though it will just keep failing every single time.It just goes round in a loop watching from the ilo, it first does choose AHV re image, the it reboots and get to that same screen and then just boots to current AHV OS.So is there a way to do this manually without it affecting the CVM’s config running on them?ThanksMark

HiI’m reviewing the network design for a Nutanix AHV cluster and I would like to clarify best practices regarding CVM backplane traffic.Specifically: Is it considered a best practice to separate the CVM backplane (CVM-to-CVM traffic, Stargate/metadata replication, etc.) onto a dedicated network or VLAN? Or is it generally recommended to keep the backplane traffic on the same network as the CVM/host data network (as long as bandwidth and latency requirements are met)? Assuming a standard production environment (10/25GbE, properly sized switching, no extreme east-west congestion), does separating the backplane provide measurable operational or performance benefits? Is it buggy in therms of troubleshooting? does it mainly add complexity without real gain?I’m particularly interested in official guidance or field experience from larger deployments.Thanks in advance!

HI!Microsoft certificates for Secure Boot expire in June 2026Will AHV, CVM, and VM legacy boot continue to function properly after the certificate expires?Secure Boot expiration will only affect guest VMs using UEFI? 

Hello, we are experiencing issues trying to deploy AppsAnywhere appliances (based on Rocky Linux). Issue as I understand is AppsAnywhere appliances doesn’t come with correct drivers for Nutanix. Official line from AppsAnywhere is they currently don’t support Nutanix, but their support and development teams are in contact with me via support case. Couple of years back when we migrate from VMware we used Nutanix Move and a root account, I guess this take care of the drivers, and appliance works fine.We now have a new Nutanix cluster and like to deploy the latest build of AppsAnywhere, but we no longer have access to VMware. We tried following to deploy: https://portal.nutanix.com/page/documents/kbs/details?targetId=kA03200000099TXCAY and 

HiI’m looking for guidance on the best practice to upgrade a Metro Availability setup with a Witness VM and would like to confirm the recommended and supported approach.Scenario: Two AHV clusters configured with Metro Availability External Witness VM providing quorum on a third site Prism Central deployed (one per cluster) Upgrade-related questions: During maintenance, is it recommended or even possible to: Temporarily pause or disable the Witness service Upgrade Prism Central Re-enable the Witness afterward Or is this not required / not supported? Can Prism Central be upgraded without impacting Metro Availability, assuming both clusters remain healthy and communication between them is intact?

Hello,I’m reviewing the official Nutanix documentation regarding Metro Availability with Witness VM, and I have a question I’d like to clarify.We are planning a Metro Availability (synchronous replication) setup between two Nutanix AHV clusters, and we would like to deploy a Witness VM in a third site to provide quorum and avoid split-brain scenarios.From what I have seen so far in the official Nutanix documentation, most references to Metro Availability with a Witness VM seem to be focused on VMware HA (ESXi) environments, and I have not found a clear and explicit confirmation regarding AHV-to-AHV Metro Availability using a Witness VM.Could someone please confirm: Whether Metro Availability between two AHV clusters using a Witness VM in a third site is officially supported And if there is

HiI’m in the process of designing a Metro Availability architecture between two identical AHV clusters, with each site having its own Prism Central.The first cluster has already been deployed, and some VMs have been migrated to it from the customer’s legacy VMware environment. Once those VMs were running on the first AHV cluster, I assigned them a temporary local Protection Policy (within the same cluster and PC) as a precaution, in case a restore was needed during the following days. The idea is to have at least 1 daily recovery point with a retention of 7 days.At the moment, all these VMs are located in the cluster’s default container. In order to implement Metro Availability between both clusters, my understanding is that I need to: Create a new container with the same name on both clusters  Migrate the V

Hi everyone,I have a problem.The disk types in the Nutanix cluster are SATA SSDs and HDDs.ODF disks have been added to the worker nodes for the OpenShift cluster creation. SCSI was selected as the bus type, and all-flash was selected. Despite these selections, when checking within the OS, the ROTA value shows 1. In other words, the OS is recognising the disks as HDDs.  The ROTA value must be 0; the disks need to appear as SSDs. Does anyone have experience with this? How can I fix this at the Nutanix or OS level to ensure a correct connection between the VM and the hardware?

HiI recently deployed a pair of nutanix clusters with AOS 7.5 and the same version of Prism Central.This customer uses veeam 13 and he have experienced some decrease in performance due to some issues between the AHV 7.5 and Veeam 13.I’ve seen on this link from the veeam forum that the new PC 7.5.0.1 release is compatible with Veeam 13 and it may fix the performance issues.https://community.veeam.com/blogs-and-podcasts-57/veeam-plugin-for-nutanix-advisory-on-nutanix-aos-7-5-12229So now its time to upgrade Prism Central from 7.5 to 7.5.0.1 but when I perform an inventory on LCM trhough prism element or prism central I see no updates available (notice this is not a dark site). Am I missing something??thanks

Hi All,I have Dell power edge R760 server with loads of RAM and Storage. My plan is to configure this as single node cluster.is there any limit for number of Virtual Machines per single node cluster? I read that maximum 5 VM’s only allowed in single node cluster. is this true?

Hi,On a subnet with nutanix IPAM activated, is there any way to add NTP option 042 to the DHCP server, or failing that, is there any way to change from nutanix IPAM to external IPAM without deleting and recreating the subnet from Prism Central?

I’m looking at trying Nutanix, I was orginally on ESXi with a Dell PowerEdge T340, I’ve since migrated to Proxmox.I’m in the process of reading documentation and reviewing etc.  I currently have 4 x SSDs in the unit with 64GB RAM installed.  I may put an HBA330 in to allow use of the other 4 drive bays.  I have a spare BOSS card too that I’ve not used.Does anyone have Veeam CE Edition v13 appliance working with Nutanix?

Hello Nutanix Community,I’m reaching out for help after spending a significant amount of time troubleshooting an issue where a Nutanix cluster cannot complete initialization. I would truly appreciate any insight from the community, as I believe I have exhausted all standard troubleshooting paths.This cluster was previously created successfully and had been running in production without issues.However, due to security-related changes in our IT infrastructure, we were required to re-address the entire environment, including: CVM IPs Hypervisor IPs IPMI IPs Because of this requirement, I intentionally chose the cleanest and officially recommended approach, which was: Reclaim licenses Stop the cluster Destroy the cluster Rebuild the cluster from scratch using Nutan

What does this nutanix license concurrency means in Nutanix. I bought the Nutanix NCM-Pro and EUC licenses and it was committed that the licenses will be based on the number of concurrent users logged into VDI.Can some please let me know if there is any report where it shows the number of concurrent users in prism central.

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? 

Hi,I decided to write my own Terraform provider/resource for managing a StoragePolicy as the Nutanix provider does not include this capability yet. When writing the delete/destroy function, I followed the Golang example in the API page: https://developers.nutanix.com/api-reference?namespace=datapolicies&version=v4.2#tag/StoragePolicies/operation/deleteStoragePolicyById However, I found it failed with 500 using the example. After debugging I found that the client expects a map with string and pointers to string for its values, not actual strings (https:

Hi. New to Nutanix. We have a 3-node test cluster to evaluate. We are at RF-2 (1N/1D). I am hoping someone can clarify some things for me. I know I can lose 1-node or 1-drive and I will still have data availability. My question is this:If I lose 1-node will data-resilency be rebuilt in that I could actually lose a drive in 1 of the two remaining healthy nodes and still have data available? My thought process is Curator will simply rebuild the data to another healthy drive on the same node?I am trying this now where I cleanly shut a node down, and after 44 minutes Element still shows data-resilency as critical. I would assume since there is tons of free space the resilience would move to “OK” and I could tolerate a drive failure. I must really be misunderstanding something, I am certain I have read that would be work. I just cannot lose a drive with the node down during the rebuild process. Thank you for clarification!

Greetings,In our lab, we have an old Nutanix cluster of 4 NX-8155-G6 machines. I am looking at installing Open Source AHV and AOS however CE may be our solution as well. It looks like the only way to install AHV on the appliances is using Foundation. So two tracks:AHV on the old cluster and install with Foundation Install CE on the old clusterDoes anybody have experience installing CE on older Nutanix Hardware?
