VHDx file format VMs in nutanix cluster

Hi, Does Nutanix AHV allows to deploy VMDK (VMware) or VHDx (Hyper-V) file format VMs in nutanix cluster without converting it to a nutanix supported format?

Sysprep for VMs deployed from template

Hi, I have a Windows server VM. I don’t have a Prism Central and have mounted the windows server disk to image services in Prism Element. I am planning to deploy future VMs from the template. I am confused is it necessary to run sysprep after deploying a new VM from the template. Hovewer, i have done sysprep of the base VM before mounting it to Image service. Also please comment on Cloned VMs. Thanks in advance.

Requesting Compatibility: Including Cisco B200 M5 as Compute-Only Nodes in an Already-Existing Nutanix Cluster

I am currently operating a Nutanix cluster with Cisco UCSC-C240-M7 nodes. I am considering expanding this cluster by adding two Cisco B200 M5 servers as compute-only nodes. Before proceeding, I’d like to confirm the following: 1. Is it possible to install AHV Hypervisor on Cisco B200 M5 servers and integrate them as compute-only nodes into our existing Nutanix cluster?2. Are there any specific configurations or firmware requirements for the B200 M5 servers to ensure compatibility with Nutanix AHV (the blades are UCS managed)?3. Can you provide any documentation or guidance on the best practices for this type of integration? Thank you

AHV ISO Image Fail

I have some HX1021 nodes that are bare metal right now and need to have AHV installed. I’ve tried multiple AHV ISO images and AOS ISO images, but every time I try mounting them to install them, I get this error: “[6.486252] pstore: unknown compression: deflate.” I’ve tried multiple versions of these ISOs and have tried downloading them from my local computer and from my jump host. I don’t believe they are getting corrupted when being downloaded. Anyone have any advice?

AOS with Cisco B-Series Compatibility

Hi there, I have two Cisco UCS B200 M5 servers connected to two 6200 FIs. I have deeply searched in the documentation of Nutanix and found that the only supported B-series server is the M4, but its supported AOS is EOL already. And I know that the minimum number of nodes is three for a Nutanix cluster to be deployed. However, my question is: is there any possible way I can install AOS on these servers? Thanks, Osama

Packer: "press any key to boot from CD/DVD" issue

Hi, I have a successful gold image build for Windows Server 2022 that runs all the way through - building from ISO’s in the image library all run from Packer and ending up with a sysprep’d ‘disk’ in the Image library able to be deployed from… All apart from I manually have to catch the first boot of the Packer build and hit ‘any key’ to enable the initial boot from the attached ISO. In the ESXi version of the Packer plugin, there’s “boot_command” and boot_wait” options, but nothing like this seems to exist in the Nutanix Packer plugin (0.9.0) Has anyone got a solution to this problem? Seems pretty basic! Thanks in advance Tim

Display resolution in Windows Server 2016 (AHV-VM) stuck to 1280x1024

Ok, yesterday one of our many Nutanix clusters was upgraded to 5.15 LTS and I started to create a new Windows Server 2016 template using UEFI-configuration. Now I am stuck at display resolution of 1280x1024 and change is not possible, because it is grayed out. Nutanix Guest Tools from 5.15 LTS and VirtIO 1.1.5 are installed. Is this bug known and does there exist a work-around? What about 5.16 STS? Is it fixed there? Thanks for any reply. Regards, Didi7

Need help on an old cluster, Zookeeper won't start

Hi All I have recently inherited an old (el7.nutanix.20201105.30281 is the version maybe?) 4-node Nutanix cluster and very soon after first looking at it and raising myself some tasks it has decided to stop working! I do not have support (turns out that expired a couple of months ago) and while I do intend to resolve that situation I just need to get the thing back online ASAP as it runs some critical services The initial problem was caused by one of the nodes running out of inodes on the root disk. I cleared this down (it was just a LOT of emails in the spool) but the prism console was not available afterwards. Had a quick look online and restarted genesis (allssh 'genesis restart') off the back of that but it did not help The problem seems to be with zookeeper, in zookeeper.out I just see a lot of this 2024-06-24 15:51:33,093Z:26630(0x7f4343398700):ZOO_INFO@zookeeper_interest@1926: Connecting to server 10.6.232.32:9876 2024-06-24 15:51:33,093Z:26630(0x7f4343398700):ZOO_INFO@zookeeper

Moving PC from ESX to AHV

I posted last year about moving PC from a non-nutanix cluster running ESX to a nutanix cluster running ESX but we didn’t do the work at the time. Now the goalposts have moved a little, or will be and I think things will be a little bit more complicated! So to recap; currently PC (pc.2022.6.0.9) runs on a non-nutanix cluster ESX 7.x we have 2 nutanix clusters running ESX 7.x we will be purchasing a new cluster which we intend to run AHV on we will then migrate all the VM’s from the two nutanix esx clusters to the new AHV cluster we will possibly also be migrating our native Azure VM’s to Nutanix NC2 in Azure. We want to move our current PC to the new AHV cluster once its purchased. So the question is how? I was thinking of using MOVE. AIso note we AREN'T running microservices on our PC

Creating a VM with customization(answer file) with the Powershell cmdlets v2.0

Hello, With the Nutanix Powershell v1.0 cmdlets, I was able to use a customization file: $VMCustomizationFile = "adsf:///Transfer/VMCustomization/unattend.xml"$VMCustomization = New-NTNXObject -Name VMCustomizationConfigDTO$VMCustomization.userdataPath = $VMCustomizationFile New-NTNXVirtualMachine -Name $VMName -NumVcpus $vCPU -MemoryMb $MemmoryMB -BootConfig $Boot -VmCustomizationConfig $VMCustomization I have now rebuilt my script with the Powershell v2.0 cmdlets, and everything is working except the customization part. I cannot find anything about customization in the v2.0 cmdlets reference. 😞 $VMCustomization = New-NutanixObject -Name VMCustomizationConfig$VMCustomization.userdataPath = $VMCustomizationFile Has anyone else successfully used a customization file when creating a VM with the Powershell v2 cmdlets?

Nutanix data not being deleted even if VM is deleted.

Hi All, I am new to Nutanix Environment. I have been tasked to troubleshoot a customer Nutanix environment. In the Nutanix cluster storage utilization is at a critical stage, and Customer VMs are behaving strangely. VMs are gradually becoming unresponsive and we are greeted with 2048 screen stating VM boot disk are not found although the cluster storage shows 2 TiB available (I know its extremely low, things might not work). The most important part is we have already deleted almost around 15TiB of storage but we are not seeing an increment in the available storage resource. (its stuck at 2TiB). The customer environment is out of support subscription, and they are not able to renew due to their internal financial issue. Cluster version: 5.10.5 LTS Pro License Storage: 2TiB free of 55TiB Number of Nodes: 4 RF=2 Data Resiliency Status: Critical I will be very grateful for any help and suggestions. Thank You
