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

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

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?  

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

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 

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 

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?

Hello Nutanix Community,I am currently working with Nutanix Prism Central version pc.2024.2.0.8 and need to programmatically retrieve VM performance metrics (such as cpu_usage,disk, memory) via the Nutanix REST API. 

Hello, what is SELinux protection policy (hawk armor) in Nutanix and where I can find ANY info about it? This seems to be new policy in AOS 7.3 and completely ommited from release notes.http://portal.nutanix.com/kb/17892

Hello All,I need some help on how to deploy Nutanix AHV, AOS and Prism element in newly deployed DELL servers. Also, need to check which version i should go with by following N-1 principal or something else here.If someone can help on below and have queries further as wellCVM FoundationFoundation for WindowsStandalone Foundation VM Please suggest.

I am using the New-NTNXVirtualMachine PowerShell cmdlet to create a VM on an AHV cluster.  Up until now, I haven’t included the “-BootConfig” option and it has defaulted to “BIOS”. Now I need to specify UEFI and Secure Boot for Boot Configuration.  AI gave me examples and information but it must be out-dated because the properties were not named correctly.  Or maybe my cmdlets are out-dated. It gave me this:$bootConfig = New-NutanixObject -Name BootConfig$bootConfig.uefi_boot = $true$bootConfig.secure_boot = $true$bootConfig.boot_device_order = @("kCdrom", "kDisk", "kNetwork")New-NTNXVirtualMachine -Name "MyUEFIVM" -MemoryMB 4096 -NumVCPUs 2 -BootConfig $bootConfig -Cluster "MyCluster"When I tried it, I found there were actually no underscores in the name.  But I did not find any reference to a property for “secureboot”.$boot

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

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.

I am conducting a qualification of an application on AHV which requires certain SMBIOS values are set for the host VM to properly identify the platform and ensure operation. Specifically, values of smbios type 2 (baseboard) for “Manufacturer” and “Product Name” need to be set. This is normally populated by default in VMware. In Proxmox (another QEMU KVM based hypervisor) this can be easily set using the qm tool and passing the args string to update the values as needed. qm set <VmID> --args "-smbios type=2,manufacturer=<vendor>",product=<model>"Exhaustive searching leads me to acli vm.update “extra_flags” option but I don’t see any options to add SMBIOS information. Looking for guidance from the community while also working with Nutanix Support. Thanks! 

Does Prism Central supports 2FA ( OTP or Captcha)

Hello All, I will like and understanding of the Nutanix system accounts Admin/Nutanix etc.We have a cluster of 3 nodes.I’m able to login via Gui with admin account on PC. (not a problem)I’m able to login via ssh to each CVM node with admin account. (not a problem)If i try to login to same ip via GUI with the admin account i get this error (Unable to authenticate. Please contact the Nutanix administrator.) Is the CVM admin account different from our Prism Element admin account?(we can’t login to PE with our admin account)If so which account can i use to change the password for PE admin account?   

Hello, I have 3 node cluster setup and working fine and it is also integrated with PC as well and the VM is in the same cluster itself. I am just curious to know. Just curious to know, how to VM auto start works in this case. Like in VMWARE we use to manually select startup feature and  configure VM Startup Priority by +1. What concept is use in nutanix, and how can we prioritize that? 

I was testing Link Failover and it was not working as expected. I have configured ACtive-Standby, and once I am taking out the cable from NIC1 all the traffic does not goes through Standby link, after connecting nic back, the traffic was also restored. Just want to know the faiover scenario related to NIC. Note : Time seems to be correct in every CVM Once the traffi is back I am trying to access CVM with virtual IP giving below error
