CPU frequencies in AHV vs in VM

Hello, We have recently set up a new Nutanix infrastructure consisting of two clusters, each with three AHV nodes. The hardware comprises ThinkAgile HX650 V3 CN servers, equipped with Intel(R) Xeon(R) Silver 4416+ CPUs (2GHz, up to 3.9GHz). The BIOS of the AHVs is configured to Performance Schedutil. Our concern is that the VMs are operating at a CPU frequency of 2GHz. Monitoring shows that the CPU frequency never exceeds 2GHz, while the AHV CPUs average around 2.8GHz. Is this behavior a bug, or is it by design? Is there a way to change and increase the CPU frequencies used by the VMs? We are still learning about the Nutanix infrastructure and would appreciate your assistance. Thank you.

Can't enable NFS, even after updating to the newest version.

Hello! I’m unable to enable FNS on my test CE nutanix cluster, even after updating both Element and Central to the newest version using LCM. If anyone have any clue of what I’ve done wrong, it would be much appreciated.

How to increase the sinze of Prism Central?

In this single-node hardware environment (24C/384GB/4x800GB) I have installed Nutanix CE 2.1 which work fine. I then wanted to test Prism Central and deployed it in size x-small which turned out to be too small (could not do all fun stuff). How do I increase it to size small instaead? I tried to just add the extra cpus and memory to match the size of small, but that was not enough, it still said that it was x-small. Then I tried to remove PC to create a new larger one, but it wasn’t as easy as I thought. The VM wasn’t possible to delete without deregister but the deregister was blocked but a objects-lite database which wasn’t possible to remove! It just referred to KB-17159 which literally only said “Contact Nutanix support”… But this is CE and I’m just a partner playing around without support… Any procedure for size upgrade of Prism Central? (I searched in the portal but failed)

Is Network Controller supported on Community Editon 2.1?

Hello, just finished installing a new CE 2.1 cluster to experiment a bit, and a new Prism Central. Trying to enable Network Controller, but it says my cluster is not supported. Is this not a feature supported by CE? Or would I have to use a different Prism Central version?

Community Edition, can't reach CVM's when trying to segment backplane LAN

Hi! I’m trying to segment, the backplane LAN on an already existing cluster, it passes the validation, but then I get this error when it gets to about 45% Anyone know what i’m doing wrong?I’m following this documentation Link My CVM’s use 10.10.10.11,21,31 And AHV use 10.10.10.10,20,30 Trying to get the backplane to use a 10.10.11.0/24 on a different physical switch. All ports are VLAN tagged with VLAN11 just like the This is the error I get When looking in the Foundation logs, they fail to ping eachother, but I don’t know what the issue there could be, they are using the correct IP’s and the interfaces are up on both sides.

Can Foundation create clusters in VMware Workstation?

In my struggle to find some environment to practice/test Nutanix admin stuff, I’ve now come to Nutanix Foundation (NCE 2.0 worked but is old, NCE 2.1 failed on some networking issue in my environment). Is it possible to create a small single node cluster running as a VM in VMware Workstation using for example Foundation? I made a few tries but it seemed Foundation required IPMI access to the host, but VMs in VMware don’t have IPMI (to my knowledge). It thought maybe a new VM could be recognized by Foundation (tried both the Windows version and the VM) if it had booted DiscoveryOS, but I couldn’t find the Discovery OS image anywhere… Is there a way forward for an installation like this or is it a dead end?

Updating tools results in hanging at uefi upon reboot. Has to be power cycled to then boot to Windows Server

SCSI disk 100gb, 16gb mem, Server 2016 standard desktop experience, dual xeon icelake Likely other configurations, as this has happened with multiple VMs, still collecting data, but wanted to get something started in case others have experience with this. My first thought is obviously some uefi configuration with boot order or something, but doesn’t really make sense, since it only *seems to happen* right after tool updates. *updated as it’s not like we reboot often, maybe it will happen without updating as well.

Nutanix CE Installation Issue - InstallerVM Timeout

Hello Nutanix Community, I'm trying to install Nutanix Community Edition (CE), but I'm encountering an InstallerVM timeout issue. The installation keeps retrying, and the hypervisor setup does not complete successfully. My hardware setup: 1 HDD (480GB) → Intended for data storage. 1 SSD (2.8TB) → Assigned to CVM storage. 1 USB Drive (32GB) → Used for the hypervisor installation. Issue Description: The installation starts but gets stuck with repeated messages: INFO Hypervisor installation in progress INFO InstallerVM timeout occurred, current retry 0 I have already disabled RAID and set the SATA mode to AHCI in the BIOS. The disks are correctly recognized when using lsblk and fdisk -l. I tried wiping the disks (wipefs -a and dd if=/dev/zero), but the issue persists. Troubleshooting Attempts: Checked system RAM → I have more than 32GB available. USB Boot Media → I recreated the bootable USB with a fresh Nutanix CE ISO.

One Click Prism Central Deployment is Failing because of timeout

Hi Team I am trying to setup Prism Central in Nutanix CE. I have configured the required details in Prism Console for deploying prism central. My deployment is failing repeatedly and getting the error saying it’s failed in tarball extraction phase. I have tried multiple times and every time I saw the issue in UI. I went through the /home/nutanix/data/logs/genesis.out logs to get more details on the issue. I found something interesting there. When we start the Prism central deployment, it first tried to download the prism central tarball and unzip it. One it’s unzipped then it’s start to convert the qcow2 file to image. when it start to convert the qcow2 → image , the command is configured with a timeout of 1800 sec. Please have a look into the below log line. 2024-07-01 08:55:17,702Z INFO 25030000 uvm.py:1606 Running cmd ['/usr/bin/timeout', '1800', '/usr/local/nutanix/bin/qemu-img', 'convert', '-p', '-f', 'qcow2', '-O', 'raw', u'nfs://127.0.0.1/default-container-40804253832490/pc.2022

Core Licensing Issue on Cluster

We are planning to renew license for below nodes Nutanix(HCI) NX-1265-G7-2 Nodes Nutanix(HCI) NX-8135-G7-3 Nodes But in the same cluster we have four G5 nodes as well, When we try to apply core license through PC, It doesn’t allow us to only license G7 nodes and we need to select all the cores from all the nodes, It seems that we need to separate the G7 nodes from the cluster just for the licenses to apply, Are we missing anything ?

How to enable network port forwarding on Nutanix AOS/AHV server?

Looking for best practices or examples for enabling port-forward traffic from Nutanix AOS/AHV hypervisor to the VM. Here is my setup: Successfully provisioned Nutanix AOS/AHV hypervisor on the PowerEdge server. Enabled OS to iDRAC passthrough using PowerEdge iDRAC settings as per the document Accessing redfish API via OS-iDRAC interface is successful as shown below: # curl -k https://169.254.0.1/redfish/v1{"@odata.context":"/redfish/v1/$metadata#ServiceRoot.ServiceRoot" …., Next step I would like to perform similar redfish query from the VMs. How do I enable port-forward using NAT on AOS/AHV; so that PowerEdge iDRAC redfish service network is accessible from VM? Thank you. Viswanath
