Deployment Success

Hi TeamDoes Nutanix support IPV6 based VM deployments. Currently I am using Prism Central V3 API for deploying VM https://www.nutanix.dev/api_reference/apis/prism_v3.html#tag/vms/paths/~1vms/postIn the payload section it is mentioned that IPV4 support is only available now. If we want to do IPV6 based deployment, is there a workaround for that? Please share the document reference if IPV6 based VM deployment is not possible. If a workaround is there, please let me know how to do this. ThanksAkash

HiI am trying to install the community edition on three nodes and on each one it keeps on getting stuck on this screen I have tried multiple times and wait over 30 minutes any ideas? 

I have installed CE 2.0 on 3 Supermicro servers. AHV is up, and the CVM is running. The Genesis service is running on all 3 nodes. When I issue the command to create the cluster and use a comma separated list of IPs, I receive the following error (same error regardless of which CVM I run the command from):MainThread cluster:1001 Could not discover all nodes specified. Please make sure that the SVMs from which you wish to create the cluster are not already part of another cluster. Undiscovered ips : localhostThe localhost part is throwing me off. Any ideas? I can ping all the CVMs from all the other CVMs. I have restarted nodes, restarted genesis, and used the --skip_discovery with no luck. Any help would be appreciated. 

I’ve attempted to install a single node cluster (many times) and seem to have the same issues.  Post install, the cluster is not created.  Genesis appears to not be installed or running? I can ping and ssh between AHV and CVM.  Some issues I see leveraging the ‘troubleshooting common nutanix issues’: 

I’ve tried installing AHV/CVM and have ran into a multitude of issues.  However, I thought I finally got a successful CE up.  I was able to SSH to CVM, verify Genesis was running.  Yet I randomly get issues with this VM and the network and now, yet again, I can’t access the CVM or even the GW.  I’m following this doc: :https://www.jeroentielen.nl/installing-nutanix-community-edition-ce-on-vmware-workstation/.I’m also doing some troubleshooting from: https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000LM8BCAW and not getting anywhere.Sometimes I can ping the GW, sometimes I can SSH to the CVM, sometimes I can’t. 

Erasure coding is a data protection method that breaks data into pieces, adding redundancy for fault tolerance and data recovery. When we enabled RF2 on the cluster that copies data in two different nodes for fault tolerance, should I use erasure coding on the cluster? what is the benefit?

Hi While troubleshooting a performance issue with some VMs on the cluster, we noticed that the cluster-wide latency, as shown in the Prism graph on the front page, was around 23ms on average. This is significantly higher than our usual 10-12ms. Upon further investigation by support, the issue was traced to two VMs with high I/O activity, writing large blocks of data (over 1MB in size). To troubleshoot, we added the following graphs for each VM: Storage controller bandwidth (MB/s) Storage controller latency (ms) I have a few questions: Why is the term “bandwidth” used instead of “throughput”? My understanding is that bandwidth refers to the capacity (size of the pipe), while throughput is the amount of data passing through it per second. If the average cluster latency is high, wouldn’t this impact other workloads? Does the term “storage controller” refer to the CVM?Thanks in advance

Hi! I’m trying to complete my first Prism Central deployment on a test lab, however whenever I try to connect my cluster to the PC, I get the following error, any idea on where I may have went wrong? I can login to the PC just fine, and everything pings each other with no issue. 

Demoing CE edition for alternative to ESXI.  Finished Install.  CVM Won’t start.  I check virsh list --all and nothing is in the list. Demoing on a i5, 32 Gb of Ram.  I’ve been combing through the forms and looking for any insight on what the issue could be.   

Hi,I’ve been trying to install Nutanix CE 2.1 (from this post) on a bare metal server bought from OVH (RISE-1-11) with the following specifications:CPU: Intel Xeon-E 2136 - 6c/12t - 3.3 GHz/4.5 GHz RAM: 64 Go ECC 2666 MHz Disks: 2×512 Go SSD NVMe 2×4 To HDD SATA After multiple tries (OVH’s IPMI/KVM feature is pretty bad so I had a very hard time completing the installation process), I finally succeeded to install the ISO on this machine.However, once I boot in AHV, I try to ping the CVM but get a Destination Host Unreachable error. After checking with virsh list --all I found out that the CVM was in a shut off state. I tried to start it with virsh start <CVM_NAME> but got the following errors from qemu:error: Failed to start domain ‘NTNX-b05f675e-A-CVM’error: internal error: qemu unexpectedly closed the monitor: 2024-08-28T14:42:04.640171Z qemu-kvm: warning: Large machine and max_ram_below_4g (536870912) not a multiple of 1G; possible bad performance.2024-08-28T14:42:04.653150Z

Hi, I am considering Nutanix for our use-case. We have a HPe DL385 server with 2 L40S GPUs. I understand that Nutanix is supported by NVidia, which is an important plus. However, I am trying to install Nutanix on our server, and now see it requires 3 *physical* drives to operate. One for the Hypervisor, one for CVM and at least one for Data.  As we only have 2 (RAID 1) NVME, and 1 Data drive, we cannot proceed installation. I am not looking forward to sacrifice an entire Data drive (3TB) to a CVM / Hypervisor of only 200 GB. However, the installation does not seem to understand partitions in a drive.  Can you confirm that the Nutanix installation requires 2x *physical* drives to work? Or is there still a workaround to have it understand partitions?Thanks!

I have a difficult problem, and have no idea how to fix them. I installed Nuntaix CE on VMWare Workstation 17 Player, however when I enabled the CVM, there were two errors as below, please help me, if you have some methods to fix. Thank you very much 

Hi,I am checking out Nutanix as a hypervisor. I understand however from our technical supplier that Nutanix will not be able to scale a GPU server using a storage server. Namely, I have a GPU server with some limited storage, which I would like to extend with a storage server(s). These would then be linked through a dedicated switch to the GPU server.He tells me that Nutanix is not good for that, and that we would have to go with VMWare. I understand that this has to do with hyperconverged infrastructure (HCI). However, I cannot imagine that Nutanix does not have a solution for such use-case. My question therefore is: can a GPU server be extended with a storage server using Nutanix?Thanks!

Does anyone have any documentation on the upgrade steps for nutanix firmware with LCM? I want to perform a firmware upgrade on my Nutanix cluster.   

Howdy all. I’m trying to install Nutanix CE on a blade server to evaluate it as an alternative to VMWare. I keep getting this error when installing though, before being dropped to a root shell.NFO Phoenix ISO is already mountedNFO Picking the bundled hypervisor:/mnt/sum_installer/./install/ahu/kum_hostATAL An exception was raised: Traceback (most recent call last):File "./phoenix", line 152, in <module>main()File "./phoenix", line 87, in mainparams = gui.get_params (gui.

Good evening Nutanix’ers, After I configured an active-active bundle on my virtual switch in PE, and modifying my upstream switch with LACP, all seemed well. However, I noticed that the hypervisor rolling reboot never finished, and its been stuck at 90% for ~3 hours. When viewing incomplete tasks in ecli, I noticed that the virtual switch update and hypervisor rolling restore are both stuck at “kRunning.” Screenshot I am thinking about killing the rolling restart task, however doing so warns me that “Using this command can cause database corruption and complete system failure, if used improperly.” I admit that I may have not fully appreciated a step about maintenance mode when following this kb here for this specific configuration, so if I’m borked, then I’ll chalk it up to a learning experience. However, I’d like to see what my options are :). Despite all of this, I’ve confirmed LACP is negotiated, and the rest of the system seems normal despite the stuck task. What do you guys think?

Hi teams,I try to register Azure environnement on Move 5.3 but always have “Time Out” error like belowRequiements are oki following this step .Any Ideas ?Thnx 

I understand that the Witness service is now integrated with Prism Central in version 2024.1. Given this, if we still want to set up one Prism Central in Site A or Site B (within a Nutanix environment) while placing the Witness VM in a third site (Site C, which only has a VMware environment), is this setup possible?Thanks in advance!

Hi Nutanix Peeps, I am new in HCI technology and would like to seek your insights on how to configure native VLAN in the Nutanix Environment. The plan was to remove the default VLAN (Data Traffic) to all Cisco access switches therefore removing it will also require to configure new native VLAN in the trunk link between the switches and Nutanix Hosts. Any help would be pretty much appreciated. Thank you so much!
