AHV Virtualization

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?

HiI have a customer with an old Nutanix AHV Cluster:Prism Central: pc.2023.4.0.2  AOS: 6.5.6.6  AHV: el7.nutanix.20220304.511 We wil deploy a new Nutanix AHV Cluster:Prism Central: 7.5.0.6  AOS: 7.5.0.6 AHV: 11.0.0.2  But the problem here is Veeam compatibility between enviroments. Right now the customer has two Veeam 12 apliances, the initial proposal was to eliminate one of them and use a single Veeam appliance with Veeam13.However when I was checking the compatibility matrix I can see the following info:https://helpcenter.veeam.com/docs/vbr/userguide/ahv_system_requirements.html?ver=13https://portal.nutanix.com/page/compatibility-interoperability-matrix/software?partnerName=Veeam&solutionType=Data%20Protection&componentVersion=all&hypervisor=AHV&validationType=all As far as I understand from the previous links if you want to use Veeam 13 you need at least:Prism Central → pc.2022.6 or above AOS → 6.5.6.6 or above AHV → 10.3.1.1 or above So checking the inventory from

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.Thanks in advance!

Prism central showing disconnected on prism elements. but VM is power on and also pingable. getting this error. 

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     Type            Status          Creation Time(UTC)      Completion Time(UTC)ffc53d0a-6e9e-41c7-7c4f-d9b337263be3                            kGenesis        3

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

HiI’m reviewing the network design for a Nutanix AHV cluster and I would like to clarify best practices regarding CVM backplane traffic.Specifically: Is it considered a best practice to separate the CVM backplane (CVM-to-CVM traffic, Stargate/metadata replication, etc.) onto a dedicated network or VLAN? Or is it generally recommended to keep the backplane traffic on the same network as the CVM/host data network (as long as bandwidth and latency requirements are met)? Assuming a standard production environment (10/25GbE, properly sized switching, no extreme east-west congestion), does separating the backplane provide measurable operational or performance benefits? Is it buggy in therms of troubleshooting? does it mainly add complexity without real gain?I’m particularly interested in official guidance or field experience from larger deployments.Thanks in advance!

Hello, we are experiencing issues trying to deploy AppsAnywhere appliances (based on Rocky Linux). Issue as I understand is AppsAnywhere appliances doesn’t come with correct drivers for Nutanix. Official line from AppsAnywhere is they currently don’t support Nutanix, but their support and development teams are in contact with me via support case. Couple of years back when we migrate from VMware we used Nutanix Move and a root account, I guess this take care of the drivers, and appliance works fine.We now have a new Nutanix cluster and like to deploy the latest build of AppsAnywhere, but we no longer have access to VMware. We tried following to deploy: https://portal.nutanix.com/page/documents/kbs/details?targetId=kA03200000099TXCAY and https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_7_5:mul-ova-deploy-as-vm-t.html but the appliances only boot in to an emergency mode! I have a request and a question…Request: If you can please vote for AppsAnywhere to s
