Where is LACP in ovs-vsctl show ?

I am curious why the running “ovs-vsctl show” on a AHV host does not show any “bond” whereas the “ovsdb-client dump | grep -i lacp” command and the Prism GUI show lacp is present (the switch too) ? Here is the GUI view full “ovs-vsctl show” output from AHV host: [root@NTNX-895b5886-A ~]# ovs-vsctl show84a00041-1b46-44f0-99a1-01a0b1a66713 Bridge br.mx Port br.mx.u.br1 Interface br.mx.u.br1 type: patch options: {peer=br1.local.d} Port br.mx.u.br2 Interface br.mx.u.br2 type: patch options: {peer=br2.local.d} Port br.mx.u.br0 Interface br.mx.u.br0 type: patch options: {peer=br0.local.d} Port br.mx Interface br.mx type: internal Port br.mx.d Interface br.mx.d type: patch options: {peer=br.microseg.u} Bridge br.dmx Port br.dmx Interface br.dmx type: internal Port br.dmx.u Interface br.dmx.u type: patch options: {peer=br.nf.d} Port br.dmx.d.br0 Interface br.dmx.d.br0 type: patch options: {peer=br0.u} Port br.dmx.d.br2 Interface br.dmx.d.br2 type: patch options: {peer=br2.u} Port br.dmx.d.br1

Nutanix CE installation hang up to a shell

I tried installing Nutanix CE. Created boot USB with rufus, booted and the installation starter. I can see NIC are looking for IP addresses, and one of the interfaces receives an IP from DHCP server. After some time I get the error message with starting a service: [FAILED] Failed to start Systems Management Device Drivers After that the installation hang up to a shell with some Python related error: SyntaxWarning: “is not” with a literal. Did you mean “!=”? I know this is just a warning message, but I have there several lines of error ending with: AttributeError: ‘NoneType’ object has no attribute ‘dev’ The server is R630 with two CPUs, 4x NIC (Broadcom and 2x 10Gb Intel (where the network cable is plugged in).

Flexibility issues with NIC movements in and out of Virtual Switches

I’m getting failed when I try to move some physical NICs back into a virtual switch. Will I need to do something manually?

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)

Creating template from VM - sysprep questions

I have a question. We are migrating from VMware to AHV. While we’ve been running VMware on top of Nutanix for years, now we’re using AHV instead of ESXi. On ESXi I had a number of VM templates for different OSes. I’m unclear on how to do the same under Nutanix. I have a working VM that want to convert into a template. On VMware, the sysprep step was kicked off by the “Create a VM from this template” option, when using a Customization configuration . Meaning I didn’t have to manually ever run sysprep, and the sysprep application was not needed in the template itself. Sysprep was run and invoked by the vSphere customization script. How do I do the same in AHV? IOW, I want to just “Create VM from template”. Do I have to run the sysprep command manually myself, before I convert the VM to a template? Or does the customization step do that? If so, where do I upload sysprep so that the customization step has access to it? https://portal.nutanix.com/page/documents/details?targetId=AHV-Admin-Gu

Unable to Complete Next Authentication for Nutanix Community Edition

I have installed Nutanix Community Edition but cannot complete the Next authentication. I have configured the IP of the CVM and the external IP of the cluster. The CVM can resolve the name of www.nutanix.com. I can log in to my.nutanix.com, portal.nutanix.com, and next.nutanix.com. However, when I enter my email address and click "Get Started" at the following URL, I receive the message below and cannot proceed: "It seems your My Nutanix account is not activated, please go to my.nutanix.com to complete the process" https://www.nutanix.com/products/community-edition/register I have already created an account and can log in freely.

Supported upgrade Broadcom VMWare on HPE

Nutanix Compatibility matrix shows that they support the next version of VMWare but there is no 1-click upgrade. I am running on HPE machines and we have been burned in the past where if we use an “off the shelf” ESXi .iso from VMWare it breaks the linkages from VMWare to Nutanix. We can only use an HPE branded (drivers included) VMWare .iso so that the Nutanix tools (vsan and VAAI) work. Broadcom has taken over VMWare they do not supply HPE branded .iso for upgrades according to the Broadcom case I opened. Nutanix does not supply upgrade paths for VMWare according to the Nutanix case I opened. HPE does not integrate with Broadcom anymore according to the HPE case I opened. How do you upgrade your VMWare deployment on a Nutanix linked Prism Central without a full rebuild?

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.

Uplink recognition issue on a specific server after initial installation

I have a question. I installed AHV on three servers and successfully configured a cluster. I left the network settings as default during the installation. However, after the setup, when I check the Network Configuration, I notice that on one of the servers, all uplink ports are missing. The strange part is that this doesn’t always happen on the same server — it randomly affects one of the three servers. On the affected server, all uplink ports are shown as disconnected. So I try to configure the bond again by selecting the disconnected uplink ports. When I do this, the server enters maintenance mode and starts a rolling upgrade process, but it never completes — it just stays stuck in a pending state. I checked the server’s BIOS settings, and everything looks normal there. What could be causing this issue?

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.
