Hi Nutanix Community,I'm working on integrating with Nutanix API v4 (/api/vmm/v4.1/ahv/config/vms) for VM discovery and need guidance on the best approach for extracting VM IP addresses.I see multiple IP fields in the response and I'm not sure which one to prioritize:nicNetworkInfo.ipv4Info.learnedIpAddresses networkInfo.ipv4Info.learnedIpAddresses assignedIpAddressesand more. Is there a single field that always contains the VM's primary IP address? I'd prefer to check one reliable source instead of multiple fallbacks. What's the difference between nicNetworkInfo vs networkInfo - are they duplicates or do they serve different purposes? Thanks!

Hello.The LCM UI page does not open like the image below.Recent work statusAOS 5.20 versionNX-1075-G8Proceed with LCM Update OperationIt was confirmed as the version below LCM 2.5, and we updated it to local dark site VM with LCM 3.1-H.After the normal update, the update to the latest LCM version LCM 3.2 was completed using the Directupload function of the activated LCM.After completing the job, the LCM page was fine and the job was finished.The next day, the LCM page appeared empty on the Prism page.Other Home or other tabs are fine.I tried to take action with KB-14940 but there was no change.I need help with what I can do in this situation.For your information, the PC is not configured.

Hi All,When I try to run a playbook using the IP address PowerShell action, I get this error. I've already checked that the PC is reaching the WinRM ports and that CredSSP is enabled.

In Nutanix Prism Central, Is there any top-level REST API that lists all supported API versions? like v2, 43, v4.0 etc.?In platforms like Pure Storage, etc., there's a REST API endpoint (e.g., GET /api/api_version) that returns a list of all supported API versions. It is useful for automation by dynamically retrieving supported REST API versions.Is there any such REST API endpoint in Nutanix?

Hello!! I have one of the nodes where I can’t ping it or reach it but I can reach the CVM after a failed update.I can still access the node with VNC through the IPMI.  I run cluster status and saw this:CVM: 10.74.98.23 Maintenance I got them out of maintenance mode like this:ncli host edit id=000636af-8bc1-dd2d-13dc-1866da8b319f::5 enable-maintenance-mode=falseacli host.exit_maintenance_mode 10.74.98.22 I can see now that is no longer in maintenance mode but it still unpingable:nutanix@NTNX-20640147-A-CVM:10.74.98.21:~$ acli host.get  10.74.98.2210.74.98.22 {  cclm_port_slots: 10  cclm_ports_assigned: 0  cpu_usage_ppm: 188358  cvm_memory_size_bytes: 21474836480  cvm_num_vcpus: 8  cvm_num_vnics: 3  cvm_uuid: "6e8a38fe-d70f-4aab-9f41-808af158b4c1"  host_overhead_bytes: 5633585710  logical_timestamp: 439  max_mem_ha_reserved_bytes: 0  mem_assigned_bytes: 0  mem_usage_bytes: 35147780096  memory_size_bytes: 371301810176  node_state: "AcropolisNormal"  num_cpus: 32  pool_size_bytes: 0  sched

HiI am planning to migrate our monitoring system from API v3 to API v4. For the next 1.5 years, until API v3 is deprecated, it will be necessary to support both APIs.Based on my understanding, API v4 is supported from AOS version 6.8 and above. Our infrastructure includes a variety of PCs with different AOS versions, some of which are new (v7.0) and others that are older (v6.5) but still in use. Consequently, we need to continue utilizing API v3 for the older versions.To ensure seamless operation, I intend to implement backward compatibility to maintain both APIs until all PCs are updated, which is not expected to occur in the near future.Initially, I considered checking the AOS version or the supported API versions to determine the appropriate API version to use. Is there a general API call (not specific to any version) that can retrieve the AOS version? Please note that I do not utilize the official SDK and have developed my own implementation tailored to our specific requirements.Cu

Hi Team, im trying to get the vm details using rest api 3 version,  by using the following payloadcurl -X 'POST'  -uxxx:xx   'https://onwer.com:9440/api/nutanix/v3/vms/list'   -H 'accept: application/json'   -H 'Content-Type: application/json'   -H 'X-Nutanix-Client-Type: ui'   -d '{  "kind": "vm",  "sort_attribute": "string",  "length": 2000,  "sort_order": "ASCENDING",  "offset": 0}'Here, if you see the 2000 length I have specified, but it's giving 1000 values only. Is there any other limit we need to increase ?For the same rest api Also, I'm getting “RangeError: Maximum call stack size exceeded” in the REST API explorer. Any suggestions for this ?

Hi Team,Part of automation, i need a vm’s cpu,memory for validation. right now im using rest api to get the vm details filter out, but when the vm numbers are more than 1000, its failing. is there any other way we can get these details 

We are in the process of refining our upgrade procedures with LCM 3.1 and reviewing the Upgrade order for a dark site method. We see a line for ‘Upgrade Cluster Maintenance Utilities’. The latest version for CMU appears to be 2.0.3 back in 2020. Is the utility still in use or is this being phased out?

Hello,We are working on provisioning and deploying Cisco Firepower Threat Defense Virtual (FTDv) on Nutanix AHV using an API-based approach. Previously, we used Nutanix API for ASAv deployment, and now we want to validate whether FTDv can be fully provisioned using Nutanix API alone, without requiring manual steps during deployment as discussed in following https://www.cisco.com/c/en/us/td/docs/security/firepower/quick_start/consolidated_ftdv_gsg/ftdv-gsg/m-ftdv-nutanix-gsg.html. What We Are Trying to Achieve: Upload Cisco FTDv Image – Since FTDv requires a QCOW2 image, we need to upload it to Nutanix Image Service first. Deploy FTDv VM – We must create a VM using the uploaded FTDv image and assign networking. Apply Day-0 Configuration (Cloud-Init) – FTDv requires a Day-0 file (for IP, DNS, authentication, and FMC registration). Power On & Validate – Ensure FTDv boots with the correct settings and is ready for FMC registration. What We Need to Confirm:Nutanix API v2 vs. v3 – Nutani
