Nutanix Cloud Infrastructure

Regarding Access of Prism Central Access, I have try to access but no luck and also please guide me the step to access the CLI of CVM

When I make an API on Prism Central, I get the appropriate result. Perhaps, when I make same API call on PE, by just changing IP to PE, response is 404 not found.e,g,: root@ahv:~# curl -k -u admin:'****'   -H "Accept: application/json"   "https://<PE>:9440/api/vmm/v4.2/ahv/config/vms/{UUID}"{    "message": "The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again."} PC version and PE version: 7.5.1Any pointers, what we might have been missing?

Hello,I am faced this error when foundation nutanix , if any one faced this error??

Hello  everyone,I have a quick question for discussion regarding Nutanix cluster expansion and licensing.Currently, I have a 3-node cluster running with a specific license type. I am planning to expand this cluster by adding 3 additional nodes. However, these new nodes will be licensed under a different tier (e.g., Starter vs. Pro).My questions for the community are:Is it technically supported to have mixed license tiers within the same Nutanix cluster?Does the cluster require all nodes to share the exact same license tier for it to function properly and remain compliant?I would appreciate hearing your experiences or insights on whether this mixed-license configuration is feasible or if I must standardize the license tier across all nodes in the cluster.Looking forward to your feedback. Thanks!

An administrator is deploying an NC2 cluster on AWS in the us-west-2 region. A VPC, management subnet, and a VM subnet are already created in the target region.The management subnet has a local route and a route to the Internet. The VM subnet has a local route and a route to the NAT gateway. During the deployment, the management subnet appears in the drop-down list in the Create Cluster wizard, but cannot be selected.What is the cause of this problem?The subnet has an IPv4 CIDR block but does not have an IPv6 CIDR block.The subnet has a direct route to an Internet gateway.The subnet has both an IPv4 CIDR block and an IPv6 CIDR block.The subnet does not have route to a Site-to-Site VPN connection through a virtual private gateway.

Hi Guys,  I have a technical question for implementing multiple site into single site as a DR location using sync repository where RPO 0.Thank you for answering this question. Regards,Andreas Kuncoro

Hi Team,We would like to seek clarification regarding the storage configuration for the QRadar Event Processor (EP) instances.As per the current design, two QRadar Event Processor (EP) instances and two Event Collector (EC) instances are planned for deployment. The EP instances will be deployed on RHEL virtual machines.Our understanding is that, after the VM deployment, a Nutanix Volume Group (VG) may need to be created and presented as shared storage to both EP VMs to support an Active-Passive configuration.Could you please confirm whether a common/shared Nutanix Volume Group can be attached to both EP VMs for this purpose? If supported, we would appreciate your guidance on the recommended approach for configuring and presenting the shared storage to both VMs. We are looking for your acknoweldgement.

We are using the Data Protection v4.1 API compute-changed-regions endpoint from Prism Central 7.5 (AOS 11.0.0.1) to retrieve changed regions for VM recovery points.For most VMs, the workflow completes successfully. However, for VMs with large changed data disks, the API consistently fails with:401 UNAUTHORIZEDThe failure occurs approximately 15 minutes after the operation starts.Our current steps are:compute-changed-regions is invoked successfully for cluster prism element API - api/dataprotection/v4.1/content/recovery-points/{recoveryPointExtId}/vm-recovery-points/{vmRecoveryPointExtId}/disk-recovery-points/{extId}/$actions/compute-changed-regions Nutanix begins computing changed regions. The VM disks are highly fragmented and may contain a very large number of changed extents. Results are returned through pagination. The client continues fetching paginated results. Total processing time exceeds approximately 15 minutes. A subsequent page retrieval request returns 401 UNAUTHORIZED.Add

I have a nutanix environment Running well and it is an OT Production environment. Due to some reason I want to change the Cluster Name, so before changing, I have a doubt that will cluster name change impact the virtual machine and its operation? and do I need to reboot the cluster when the cluster name is changed to new.

Hello Since onw month, when change some VMs, of Data Protection to Ptotection Policie, show the next alerts: VSS is enabled, but Nutanix VSS provider or pre_freeze/post_thaw scripts are not installedVSS snapshot is not supported for the VM X because VSS software is not installed.I returned some VMs to Data Protection, and the alerts did not return.Why do it pass this behavior?

Hi team, quick question: Is it supported to mix NICs on the same node? Specifically, can both the Mellanox 2-port CX5 SFP28 (25G) and the Intel 2-port E810 SFP28 (25G) (E810-XXVDA2) be used together on a single node?

Hello Team,I have recently deployed a Nutanix solution, and everything is working as expected. I have also deployed a virtual machine with the Veeam Backup solution, which is running successfully.I have an external USB HDD that I would like to map or make accessible within the VM as a storage. Could you please guide me on how this can be achieved?Thank you for your assistance.

Hi community,I'm in the middle of deploying a 3-node Nutanix AHV cluster and have a question about live migration traffic behavior with and without the Backplane LAN configured.My current setup:- 3 Nutanix AHV nodes- 10G SFP+ uplinks for VM traffic (VLAN 1 - e.g 10.10.100.0/24)- 1G RJ45 uplinks for DMZ and Corp networks on separate VLANs- Backplane LAN not yet configuredMy questions:1. Without the Backplane LAN configured, when a host is placed into maintenance mode and VMs are live migrated to other nodes,  does that migration traffic travel over the VM's own network? For example, if a VM is on my DMZ network (1G), does its live migration traffic also go over that 1G link?2. Once the Backplane LAN is configured on a dedicated VLAN (e.g. VLAN 10 - 192.168.10.0/24) on my 10G uplinks, will ALL live migration traffic route over the backplane regardless of which network the VM is connected to?3. Is there any official documentation that specifically covers this default migration traffic beh

I am setting up recovery plans for disaster recovery between our two clusters. I have been through the documentation multiple times, and I still am confused by the test failover/failback subnets that are configured as part of the recovery plan. Production is easy. We have the primary cluster in one location in Subnet A. We have a recovery cluster in another location in Subnet B. I just set the production subnets to be Subnet A and B at each location respectively with their matching gateway and prefix. The Test Failover/Failback subnets continue to confuse me. The documentation indicates they should be isolated and non-routable subnets which makes sense. But WHERE are those subnets defined? We use external IPAM. Each cluster is connected to a core switch stack at its location. We have a few different subnets/VLANs defined on those core switches, with a defined IP range, /24 in each case. All VMs have static IP addresses, though the core switches do run DHCP for each subnet. We also have

I'm trying to deploy Prism Central (PC) from Prism Element (PE). Previously, I had registered a PC to the cluster and then unregistered it to redeploy a new one.However, during the new deployment, at the “Size and Scale” step, no selectable options (Small/Medium/Large) are shown — only the description text appears.Current situation:No dropdown or selectable options available No explicit error message Cluster is running normallyI'm not sure if this issue is related to the previous register/unregister of PC, or due to resource constraints, version mismatch, or a UI issue.Has anyone experienced this after unregistering PC? Is there any cleanup required on the cluster before redeploying Prism Central?

Hi Experts !We recently upgraded one of our Nutanix clusters to AOS 6.8.1.8 and started facing an issue with the Cerebro service shortly after.Symptoms observed:Remote replication alerts after the upgrade.Remote site configuration warning indicating that some CVM/SVM IPs were not properly configured on the peer site.Cerebro entering a crash loop?cluster status showing constantly changing/high PIDs for Cerebro.cerebro.FATAL reporting an error similar to: Check failed: citer != (pd.second)->snapshot_uuid_map().end() with a snapshot stuck in a pending action.It looks like there is a stale or orphaned snapshot operation in the WAL / metadata, likely triggered after the upgrade while replication configuration was not fully consistent.Has anyone already seen this behavior after an AOS upgrade?Did you resolve it by fixing the remote site configuration only, or did it require Nutanix Support intervention to skip/clean the offending WAL operation?Thanks :)

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.Thank you.

I recently deployed Nutanix , but when I am opening web browser it is showing and I belive that it might be the certificate issue.
