How To enable nested virtualization on AHV with CE 2.1

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

Create UEFI Secure Boot VM using PowerShell

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 $bootConfig -Cluster "MyCluster"When I tried it, I found there were actually no underscores in the name.  But I did not find any reference to a property for “secureboot”.$bootconfig | get-member TypeName: Nutanix.Prism.DTO.Acropolis.BootConfigDTOName MemberType Definition---- ---------- ----------Equals

Community Edition: Operation failed: NoHostResources: No host is schedulable: 14

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.

Adding SMBIOS information to AHV VM

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!

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?

VM Auto Start Feature in Nutanix

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

Nutanix Integraton with VEEAM Backup

I have an infrastructure operating on a Nutanix Cluster and Prism Element, and I have integrated it with VEEAM Backup. I possess a socket-based license for VEEAM, and the cluster appears online in VEEAM. There are about 15 VMs in my infra, and I have set up a job to back up all the VMs which are within the cluster, I start the job and observed that it is not utilizing the socket license. Instead, it's recognizing an instance-based approach and only backing up a few VMs, with the rest displaying a license overutilization error. Can any one let me know How Nutanix works with VEEAM, is it a socket based license or instance based license only.

I am dealing with weird situation, I have setup a 3 node cluster, and everything went well from installation point till the GUI. As for now every one is taking time from a NTP server, but somehow my NTP servers and changed and it has some different time which is from GPS, I tried to setup that NTP Server in the PRISM ELEMENT, but the CVMS are not syncing with correct time from new Time GPS Clock, I started restarting ChronyD services bt unfortunately nothing happened

Is 32GB Enough CVM Memory for DR?

Hello.I have a question.Resource Requirements Supporting Snapshot Frequency (Asynchronous, NearSync, and Metro) I'm inquiring because I don't understand well even if I look at the link above.Three G9 nodesI'm thinking of making three G7 nodes into one cluster.The G9 node already has a cluster configured and will expand the G7 node.The G9 node is two SSDs and four HDD hybrid HCI.G7 nodes are also six SSD All Flash nodes.G9 Node Disk CapacitySSD = 3.06TibHDD = 6.9qTibG7 Node Disk CapacitySSD = 1.92TibDR is configured in the G9 cluster that is already configured, and snapshots are being taken every two hours and sent to DR. The number of snapshots stored is two.When configuring these services, how much CVM memory should be allocated?The reason for putting the inquiry is that I set the CVM memory to 32GB with G9 initial configuration. It's been about 3 months since the configuration. CVM memory usage is over 90%.We would like to ask for your opinion as the usage increases until a memory us

LCM Not Reflecting Updated HPE Firmware Version 2025.05.00.00 on DX380 Gen11

Hi all, I recently performed a fresh installation of a Nutanix cluster using three nodes, all based on the HPE ProLiant DX380 Gen11 12LFF platform.As part of the pre-deployment steps, prior to imaging the nodes using Foundation VM (foundation version was 5.7.1), I upgraded the firmware on all three servers to Service Pack for ProLiant (SPP) version 2025.05.00.00. This firmware version was explicitly referenced in the Nutanix installation prerequisites and compatibility documentation for this hardware generation.The SPP upgrade was completed successfully via iLO on all nodes, and I validated the firmware version through the iLO web interface post-upgrade.Following the firmware upgrade, I proceeded with the node imaging using Foundation and successfully deployed the cluster without any issues. Once the cluster was operational, I launched LCM > Inventory and ran Perform Inventory to validate component versions.However, LCM still reports the installed SPP version across all hosts as 202

How to Replace ToR Switches Without Downtime?

We have a 6-node Nutanix cluster on VMware ESXi spread across two racks. Each rack has a ToR switch, and both ToRs are in an IRF stack. All nodes are dual-uplinked (one NIC to each ToR).Core switch handles L3 routing, and VLANs are trunked to the IRF stack.We're planning to replace both ToR switches with new IRF switches — without downtime.Can the community please guide on: Best practices for live switch replacement How to ensure CVM and ESXi connectivity during the change Key health checks from Prism Any Nutanix KB or doc on this

Node in maintenance mode in Prism Element

Good day.I transferred the node to maintenance mode via the prism element console, but during the migration of virtual machines an error occurred and the transfer to maintenance mode stopped.At the same time, in the prism element, the host remained in maintenance mode.When checking via the CLI on the central computer, the host is not in maintenance mode, it is also transferred to maintenance mode without errors by the command: acli host.enter_maintenance_mode and is displayed by the command acli host.exit _maintenance_mode.In Prizm Central, the host is also visible normally without maintenance mode.Please tell me, maybe someone has encountered such a problem, it looks very similar to a bug in prism element itself.The command ncli host edit id=7 enable-maintenance-mode=false did not help to solve the problem.When trying to take the host out of maintenance mode in the Prizm Element web console, an error appears that the host was transferred to maintenance mode via the CLI.

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?

Nutanix replication between two PC during upgrade

I have several asynchronous protection policies configured between two Nutanix clusters each with their respective Prism Central, one primary and one DR. I am going to perform the upgrade of the clusters sequentially on different days and I don't see any reference in the documentation as to whether it is necessary for replication during the upgrade due to version difference or possible outages. I understand that it is not necessary, but I would like to know if there is any good practice as I don't see anything in the documentation. Thanks

Upgrade Prism Central

Hi everyone,I want to upgrade my Prism Central (current version: 2024.2) to a newer version, but I must have a plan to rollback, if something happens along the way. When upgrading using LCM everything seems straightforward and easy, when the checks are done and everything, but are there any risks/losses/possible damages? Can I go back to a previous version? Is there something specific to look out for? What to do if something breaks? Thanks in advance :)

IPAM NC2 Azure

We’re about to start migrating our native Azure workloads to a cluster running in NC2 in Azure.  On our onprem cluster we use our own DHCP servers for IP management but obviously in NC2 we have to use the built in AHV IPAM.  How can we find what IP addresses are being allocated and to what VM’s?  I thought that this article would help but its not what we see in our NC2 environment.  I can see a summary page in PC which lists how many IP’s are in the pool and how many are in use but there’s no detail about what VM has what address. https://portal.nutanix.com/page/documents/details?targetId=Web-Console-Guide-Prism-v6_10:wc-network-verify-ipam-ippool-wc-t.html Am I missing something or is it a limitation of NC2?
