AHV Virtualization

 Good morning all, i have the problem, that one CVM out of a 3-Node-Cluster drives me crazy… For some reason, the CVM went unresponsive regarding it´s cluster-services… CVM itself is available via SSH and I´m able to login using the Nutanix-User CVM cluster status says:   nutanix@NTNX-xxx-B-CVM:172.18.95.76:~$ cluster status | grep -v UP2026-05-08 04:50:48,386Z INFO MainThread zookeeper_session.py:226 Ignoring passed host_port_list: zk1:9876,zk2:9876,zk3:9876 because the passed host_port_list appears to have been copied from the environment variable or gflag.2026-05-08 04:50:48,387Z INFO MainThread zookeeper_session.py:296 cluster is attempting to connect to Zookeeper (unestablished session (object 0x7f6bd2b5d220)), host port list zk1:9876,zk2:9876,zk3:98762026-05-08 04:50:48,387Z INFO MainThread patterns.py:75 Creating a new instance for ZookeeperSe

Hello everyone,I am planning a migration from VMware to Nutanix AHV.The environment still includes some legacy operating systems, such as:Windows XP / Windows Server 2003 Windows Server 2008 (non-R2) Very old Linux distributions (kernel 2.6 era)I fully understand that:These OS versions are not supported on AHV Migration is technically difficult and not recommended This would be a best-effort / temporary solutionHowever, due to VMware licensing constraints, the customer must exit VMware and migrate these VMs anyway.My question to the community is simple:👉 In this kind of situation, what has been the most effective or realistic approach you have used to migrate legacy OS VMs from VMware to AHV?Any real-world experience or advice would be appreciated.

I recently deployed Nutanix , but when I am opening web browser it is showing and I belive that it might be the certificate issue. I issued a commad to check the certificate in CVM and it is showing below and my system team already passed the date and time, what might be the other issue. Cluster is showing UP and healthy.  upstream connect error or disconnect/reset before headers. retried and the latest reset reason: connection failure, transport failure reason: TLS error: 268435581:SSL routines:OPENSSL_internal:CERTIFICATE_VERIFY_FAILED

I migrated several Windows VMs using Nutanix Move.After the migration, I noticed that the network configurations of some VMs do not match the source settingsIPv6 protocol: Disable → Enabled I checked KB-10818, but it doesn't seem to apply to my case.(Move degraded?) Network location: Public → Private (or Private → Public) Windows Firewall: Disable → EnabledWhy are these settings changing during migration? Environment:AOS: 6.10.1(Source) → 6.10.1(Target) Hypervisor: AHV 20230302.103003(Source) → AHV 20230302.103003(Target) Guest OS: Windows Server 2019 Nutanix Move version: 6.0

Hello,Today I have delivered a three node Cluster to customer.Cluster was Set Up a few days ago in my Environment with a flat Switch.Bond mode for both vswitches is active-backup.Unfortunately Customer had prepared his ToR switches with LACP.All hosts and CVMs cannot communicate.What is the recommended procedure to fix ist?Change bond Mode host by host with manage_ovs  OR Let network team configure the switches (disable LACP) and configure the clusternodes via Prism, after that let Network Team enable LACPKind regards,Thomas

Hi,I’m looking to deploy the L4 load balancers for domain controller services LDAP(S), NTP, & DNS, you know they type of thing that gets addresses programmed into devices/applications.I can create a LB session for an IP and have it listen on multiple ports 53,123,636 but when I gets round to selecting the destination VM Nic's I can only specify a single port for the destination.  Is there any way to balance multiple services from a set of hosts with a single VIP, or will I need to create an LB session and separate VIP for each of the services?Also some of the documentation i read said that It’s possible to use VM Categories to select the destination VM’s, but I don’t seem to have that option, which version do I need to be running to get that?

Hi,I am trying to deploy an AHV cluster using Nutanix Foundation VM against HPE DX380 G12 servers with iLO7, but the deployment consistently fails in Phase 1 during "Preparing installer image".The relevant error in the VM Foundation log is:Imaging requires Foundation HTTPS to be enabled on port 8001 for nodes that require HTTPS boot media.What I have verified so farOn the Foundation VM:firewalld is not running port 8000 is listening port 8001 is not listening at all curl -vk https://127.0.0.1:8001 returns connection refused curl -v https://127.0.0.1:8000 returns wrong version number, which seems to confirm that port 8000 is only serving HTTP

Hello, I have recently deployed nutanix with Foundation, and every went well and I can access the PE from web browser. But when I go the Virtual Switch section, I cannot See vs0 in Switch Tab, not sure what is the issue. I go to Cluster Setting and Reboot the cluster, but it keep on processing and so on entering in maintenance mode. Can anyone help.    Regards

We have created Auto shutdown playbook of AHV host with scheduled but facing issue, when Prism Central ON , these scheduled initiated before time and we not  able to to access prism central , so disable  playbook task. Prism element started then PC started and excuted these playbook schedule and shutdown 2 AHV from Prism cluster.

Hello,  I’ve deployed several test Nutanix Single-Node clusters for test purposes.

Estimado Foro,En relación a los procesos de migración donde el E2E, los procesos, flujos, ambitos incluso de permisos es un factor que limita y afecta una correcta migración.Queria consultar si alguien ha realizado algun documento de migración donde incluya: restricciones, compatibilidades, recomendaciones, el año anterior realice una migración en este ambito que me da un contexto inicial, sin embargo el reto es grande cuando todo incrementa en tamaño de Workload y criticidad, en este sentido si alguien tiene algun inicio seria importante lo comparta, o en su defecto lo ire documentando para aporte a la comunidad.Una consulta: alguien ha expermientado migrar un Active Directory to AHV, de pronto me puede compartir su experiencia? 

Hi,I have recently deployed a pair of AHV clusters on a customer. Each cluster has its own Prism Central cause they are going to be part of a Metro availability environment with a witness VM on a third site.Now the customer is asking me if he could have some kind of overview and managing of both clusters from a single dashboard.I think that Nutanix Central could accomplish that request, however I’ve never deployed it and I have some questions.Checking the documentation I see that you can deploy it onpremise by downloading it from each Prism Central marketplace. So I assume it will deploy a VM appliance on each cluster (similar to prism central) and I should have to config it.Are there any specific tips that you could provide before deploying it?By the way, both clusters have PC 7.5.0.5 and AHV 11, everything is up to date, so I assume there is no incompatibility with nutanix central.T

Hello,  could you please advise the difference between difference between NVIDIA GRID for AHV 10.3.1.3 (AIE)  & NVIDIA GRID for AHV 10.3.1.3 (Graphics)   and when to use each of them in addition to the requirement for each one 

Hi,I have a two-nodes cluster with Nutanix CE (AOS 6.8.1 )which was built on hybrid (HDD& SSD) nodes. There is the issue:Current memory configuration 20,20 does not support the HDD capacity on the node(s): 192.168.XXX.XXX,192.168.XXX.XXY.For All-NVMe systems sized and deployed before AOS 6.8 with a minimum of 48GB CVM vRAM, it's recommended to upgrade to at least 64GB for optimal performance. Refer to the Prism Web Console Guide for instructions on Increasing the Controller VM Memory Size. I tried to increse CVM ram size from 20GB per node to at least 40GB by following this document.Then we saw the situation below:Committed memory update intent.The task is stucking on 50%. Task status:~$ ecli task.list include_completed=falseTask UUID                               Parent Task UUID        Component       Sequence-id     Ty

HiImagine you have two AHV clusters that are Active-Active (each site has live VMs on it). They are both connected and they are doing Metro-Sync between them.Now you want to move some VMs from one site to the second site. As far as I know I could perform that migration by using MOVE or by doing a manual failover of a protection policy. Is there any way to do a “live migration” between clusters without shuting down any VM?Also, is there any way to do that even if you have Async migration?I have found this but I understand is only talking about migration between nodes): https://portal.nutanix.com/page/documents/solutions/details?targetId=BP-2029-AHV:nutanix-ahv-live-migration.htmlThanks

I’m encountering an issue where an additional IP address is attached to a VM being built by Packer - this address appears at the point Packer  runs theConnecting to VNC over websocket…andTyping the boot command over VNC…stage - so very early and no where where we have much if any control!At this point the VM isn’t even up and no virtio drivers have been loaded - and so it isn’t ‘known’ by Windows but it’s the first listed IP address so that’s the one Packer tries to communicate on - so the build fails as communication is never established.I’ve tried releasing and renewing an IP address in Windows during the build but Windows doesn’t know about the address at all so it doesn’t do anything useful.  The VM shows as having 2 addresses from DHCP in Prism Central… I’m all out of ideas!  Any insight gratefully received!

Hi Guy’s I'm trying to update our Dev environment which runs on community edition, and AOS, NCC etc all working via LCM, for the AHV though it will just keep failing every single time.It just goes round in a loop watching from the ilo, it first does choose AHV re image, the it reboots and get to that same screen and then just boots to current AHV OS.So is there a way to do this manually without it affecting the CVM’s config running on them?ThanksMark
