Nutanix Cloud Infrastructure

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

NC2 on Azure Deployment Pre-requisites-Hello Everyone,I started Nutanix Learning 2 months back and there are few questions which I am unable to find answers for, it would be great to hear from you guys, below are the questions I have-What kind of subscription one should have to create NC2 on AzureWhat kind of access (Owner/contributor) we should have Any reserved Network segment/IPs to deploy NC2 on Azure Minimum and maximum nodes we can create within a cluster or a single NC2 on Azure private cloud. Pre-requisites to deploy Nutanix MOVE

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.

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.

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?

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.

Hi,Thoughts from the community please on this one.We have two clusters, in two different data centers with NearSync to replicate VMs.  So my problem is when I do a unplanned fail-over I get a VM with a new GUID, all good, until my backup software (Veeam) sees this as a new VM and creates a fresh full backup.  How do I deal with this in a better way? A full backup of all my VMs is going to need a lot of space and time!

I has install new Nutanix CE cluster, but in proceeds of installation i has lost connection.Whan cluster was installed i has check it and see these situation:One of node is not resolved, and show only IP.I has check CVMs VM in Prism Element and see this:Only 2 CVMs of 3.What i run cluster status from CVM 192.168.1.112, i see that all services is UP When i check network configuration i see this situation:

Good afternoon.After running the NCC check, I received an error message:However, there are no errors on the disks themselves that formed the MD2 partition.There are also no hardware issues, I checked both in Nutanix and in the XCC.Is it possible to fix this problem using standard Linux tools?Here's a plan, might it work:Unmount the Partition: >umount /homeRun Filesystem Check (fsck): >fsck.ext4 -v -f /dev/md2Reboot and Remount: >mount /home

Since now 5 years i’m seeing requests for a drag n drop and/or copy paste function to be enable, all software around the are able to do it , could you please provide any valuable reason to not add this functionality to the console? I hope that you will not lose customers for a copy/paste function in the future.

Hi all, I am sometimes really wondering what programmers think when they implement features which work fundamentally different than on other similar software and are seemingly half baked. This time around templates. I would really like to know the number of templates rendered unusable because someone accidentally deleted the protection point used as base for the template, because of lack of better knowledge (ah we already deleted this VM and gone) or any visible guard rails.The expectation would be templates = (multiple) immutable images + settings. Regards

Hi all, Is creating a new image from for ex. a VMDK uploaded to an ADFS container via allow/whitelist still a thing as described in KB-2622? Uploading the image works without issues, but creating an AHV image via the AHV Image Service from the disk already located on the very same Prism Element cluster apparently not.All reference I found online was that source_url=nfs://127.0.0.1/<container>/foo.vmdk isn’t supposed to work anymore for security reasons (see KB-14160). In the KB it says to use a CVM IP instead. I however get the very same message on any of the CVM IPs as well:foo-disk-import: InvalidArgument: Address <Any CVM IP> is not supported as Remote HostAdding CVMs or AHVs IPs to the allowlist doesn’t make any difference - it just won’t work.Using acli image.create or Prism Element UI also doesn’t make a difference. Regards 

Hello guys,I found this topic https://next.nutanix.com/ahv-virtualization-27/ssh-public-key-is-removed-from-esxi-18675 from ​@mstauder  and have exactly the same issue.Since... like ever… 2022..I opened a FEAT-13832  request, but I don’t know how to check it.Nutanix need only to add a second and unmanaged authorized_keys file…Or add ssh-key define in the prism element to the ESXi … Don’t you all need this guys?  

HiI now plan to have NCX so need to which course help me to facilitate the large part of the exam

Hi Colleagues,I am trying to collect operating system information for all virtual machines through the Nutanix Prism Central v3 API.I’m using the following API endpoints: POST /api/nutanix/v3/vms/list to retrieve VM UUIDs GET /api/nutanix/v3/vms/{uuid} to check detailed metadata per VM However, in all cases, the OS information fields (e.g. guest_tools.guest_os_version, guest_info.operating_system, runtime_os, etc.) are returning null or “Unknown”, even for VMs that have Nutanix Guest Tools (NGT) installed and are visible in the Prism UI with proper OS details.Steps I’ve taken: Verified that NGT is installed and running on the VMs. Queried both /vms/list and /vms/{uuid} API endpoints. Tried multiple fields including: .stat

I am following this guide: https://www.jeroentielen.nl/installing-nutanix-community-edition-ce-on-vmware-esxi-vsphere/ I am getting this error message:  Operation failed: NoHostResources: No host is schedulable: 14There is no insight in the entire system to say why the host is not schedulable.I have allocated 100GB Memory, 16 cpu cores and 2.5TB of storage To CE 2.1.  All health checks are green.VM i’m trying to run is Linux based, 2GB memory 128GB storage without any networking.I’ve started and stopped the cluster. Entered and Exited Maintenance Mode. The system is a Dell R720 with E5 2667 V2 processors running ESXI 7.0U3o I am at a loss for why this system won’t run a basic linux VM. Any ideas would be appreciated.

Hi Everyone, I have a use case within the business where a team wants to be able to leverage nested virtualization.I’m currently running some test within our test environment but wanted to understand if there are implications from nested virtualization such as:Does having VMs within cpu_passthru=true have any performance impact on that node / cluster Live migration considerations Replication considerations 

 Hello everyone,I am new to Nutanix and I have an on-premises cluster with multiple VLANs configured in Prism Central. My VMs are currently placed inside these VLANs.I am planning to migrate everything to a new NC2 cluster on Azure, but I need to keep the same VM IP addresses.I have a few questions regarding this scenario: Is it possible to maintain the same VM IPs when migrating to NC2 on Azure? Are there any prerequisites on the on-premises Nutanix cluster to make this possible? What if the on-prem VLAN is also used by other physical servers outside of Nutanix? How would these physical servers communicate with VMs in NC2 on Azure? How can native Azure components or other third-party networks connected to my Azure environment reach the servers in this stretched network? For example, if I have some VMs on-prem, some on N

We attempted the following approaches to enable nested virtualization, but it still did not work.Approach 1:a. Created the VM and enabled cpu_passthrough=true before powering it on.Observation: We were able to log in to Windows.b. Enabled the Hyper-V feature inside the VM and restarted.Observation: The system failed to log in and entered Recovery mode.Approach 2:a. Created the VM and enabled hardware_virtualization=true before powering it on.Observation: We were able to log in to Windows.b. Enabled the Hyper-V feature inside the VM and restarted.Observation: We could log in, but the nested virtualization feature was disabled.Please advise on how to enable nested virtualization in CE 2.1

We try to activate our nvidia card in an ce 2.1, but we can not see the AHV option in the Download page.We I try to acces it directly with https://portal.nutanix.com/page/downloads?product=ahv there is always a popup asking for “Activation required”.As I only run the community edition I do not have any of the requested information (Serial Number or Service Tag or Software Registration ID).Is there still a way to get the drivers.

We have a customer running the following Nutanix cluster setup:1 cluster with 4 nodes – Dell XC650 model, each node with 512GB RAM2 clusters with 4 nodes each – Dell XC640 model, each node with 768GB RAMThe customer plans to deploy VMs with 64GB and 128GB memory configurations.Could you please confirm:Is this a supported configuration for VM deployment on the mentioned clusters?Will deploying VMs of this size cause any performance impact on other workloads in the cluster?What are the best practices or guidelines to follow in this scenario to ensure optimal performance and resource utilization?

Hello,I need to install NX-3060-G6 with the Foundation VM version 5.9, but I always get an error message.For your information, this G6 already has a system installed (Sangfor HCI). How can I perform a hardware reset of the Nutanix nodes in order to reinstall them?
