AHV Virtualization

Okay, so I am still seeing weird behavior on my AHV server.At present I am unable to log into the console. Let’s say the username password is root:test. It’s not, but let’s say it is. It tells me it’s wrong, try again. Lather rinse repeat.I go to my PC and ssh into the same box, it works. Here is what it looks like:userpc:~> ssh root@nutanix1 Nutanix AHVroot@nutanix1's password:  Last login: Mon Jul 15 20:14:14 UTC 2024 on tty1Last failed login: Tue Aug 13 18:46:23 UTC 2024 on tty1There were 11031 failed login attempts since the last successful login.Last login: Mon Jul 15 20:14:14 2024I run a command:[root@NTNX-cdb56c24-A ~]# uname -a Linux NTNX-cdb56c24-A 5.10.139-2.el7.nutanix.20220304.342.x86_64 #1 SMP Wed Oct 5 12:00:00 UTC 2022 x86_64 x86_64 x86_64 GNU/LinuxI logout.[root@NTNX-cdb56c24-A etc]# exit logoutConnection to nutanix1 closed.I immediately try to log back in…userpc:~> ssh root@nutanix1Nutanix AHVroot@nutanix1's password:  Permission denied, please try again.What in

I’ve added vCPU to the VM but on the OS is not appearing same with the configuration.Please suggest me. 

Create your own virtual networking / security lab without having to purchase hardware.Eve-Ng is similar to another popular networking/security tool called GNS3.  I’ve run (GNS3 successfully on HyperV.)Both products are network emulation hypervisors that allow you to, say, load real IOS images from your environment to run them as virtual appliances.  You can emulate routers, switches, firewalls, WAPs, clients, web servers, etc.Then you can test IOS upgrades, routing changes, or whatever you want without having to risk messing with your live environment.  It’s also a great tool for education.The environment has a visual dashboard that allows you to see your network in a GUI, similar to Cisco Packet Tracer, GNS3, or MS Visio.Eve-ng is based on KVM and appears to be running very well nested inside AHV.https://www.eve-ng.net/You will need to prepare AHV to allow the VM to run as a nested hypervisor.The following commands will allow you to do that and so far that is all that was needed to ge

I have a cluster of 7 nodes of which 2 are Lenovo HX3320 with 480GB SSD + 6 2TB HDD and I need to replace the 480GB ones with 3.86TB or larger, due to recent growth in the number of nodes in the cluster. What is the correct procedure to make the change?

Hi Teams, I’m trying to install Vcenter 6.7 on a nestred ESX6.7u3 ESXI but i’ve this error.I find it strange because the installation of ESX went without any problemIs there a CLI command to enable this option like in Wokstation Pro ?Thx for your help.

Hello,I’m new to Nutanix, we just started to work with the system and I have a small problem.Unlike VMWare Nutanix doesn’t have PowerShell Module so I’m working directly with the API.My problem is that I want to create automation for set categories and tags based on variables like the disk/VM name etc. I can’t find a way to use a token for security reasons and not send the username and password as Base64 which isn’t secure.

I would like to create a nested vSphere environment on a Nutanix cluster for testing move.I downloaded the last ova from Broadcom flying and configured the NIC model to E1000 on VM but when ESXi boots, I’ve always a NIC error.(“ no compatible network adapter found…..”)Help appreciate.Thanks,nested image > Nested_ESXi8.0u3_Appliance_Template_v1.ovaAll AHV platform up to date.

Hi team,I have some confusion kindly give us an clarity, One of my customer planning to deploy vSphere with Nutanix Cluster and what are the advantages to using AHV Nutanix Cluster and Esxi Nutanix Cluster…What are the extra features are there to use vSphere Nutanix Cluster….? why we have to integrate the vCenter with the Prism Element…? what are the advantages..?and what things we have to do in vCenter level after cluster deploying…….. please give an clarity…….

Click on Server Health -> Health Event Logs. Click on ALL EVENTS in log category, select ALL SEVERITIES and click SAVE (shared logs with support) idetified memory module  support engineer raise the part replacement order  replace the part with the help of onsite engineer  run NCC and all well 

Hello Team. <issue summary>Windows server 2016 VM was restored after async DR to another cluster. If I check through Prism or CVM acli, the local vdisk looks normal in the list.However, some local vDisks are not recognized inside Windows OS.The disks are not identified in "Create and Format Hard Disk Partitions" at all.The weird thing is that other local vdisk looks normal.VG attached in DAS way looks normal vdisk.async DR was performed from AOS 5.20.5 to AOS 6.5.5.5. <Current Environment>- AOS 6.5.5.5- OS : Windows Server 2016 Standard- VirtIO : 1.2.3- vdisk bus : scsi If you restore it from the AS-IS cluster and check it, the local vdisk looks normal on the OS.In a TO-BE cluster, some local v disks are not recognized by the OS.Has anyone had a similar experience?If you have any, please tell me about the solution or cause. Thank you.

Hi Team,We are trying to deploy NCI cluster and env is Cisco C series M7 connected fabric interconnect, UCS domain mode deployment. Nutanix AOS/AHV- 6.5.5.7 version. 1. Looking for information on how many MAC pool required . As the document says to create a default MAC pool and unique MAC pool. is it 2 pool required.2. Normally there will be separate MAC pool for each FI /Fabric interconnect which will be used for server based on connection. For instance, server A has 2 NIC and 1Each connected to FIA and FIB. Both NIC cards will get MAC ID from deferent pool. In Foundation only one MAC pool can be used and that should be default MAC pool. do we have create 3 Mac pool default , MAC-A and MAC-B pool. If yes, were we can provide MAC-A and MAC-B pool info when deploying.3. Regarding VLAN created for NCI cluster in UCS Manager. If we create multiple VLANs, ex for CVM/ AHV, for VMs. How /where we can tag them. As in Foundation only one VLAN can be used.4.  Regarding UCS manifest file vi /hom

i want to migrate VMs from ahv to ahv in the same cluster (let say from node A to node B) but the VMs status is powered off, in my case i dont want to powered on the VMs, i just want to migrate the VMs to another host without powered it on(live migrate). is there any workaround to do that ?Thank you all

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?

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. 

I have tried to delete contents of recycle bin but the job has finished. I can't see the result on the overview. Can you assist for me? 

How to identify which NIC 1 NIC 2 etc or eth0 eth1 eth3 and eth4 on physical side. in my case, i want to configure the network active-backup and how to identify which port is eth1 or eth2 either on physical view or prism element dashboard  thank you 

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

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?

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

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 advanceTim

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
