offset and length parameters are ignored - Prism Central v3

Hi,In the Prism Central v3 API, when making a POST request to the clusters/list endpoint and the hosts/list endpoint, the offset and length parameters are ignored. As a result, the response returns all the clusters/hosts irrespective of the parameters passed.Has this issue already been reported, and do you happen to know when we can expect it to be fixed?Thanks in advance.

Hyper-V within a guest VM running on AHV

HiWe have a cluster running on AHV and have recently found that its not possible to host guest VMs running Hyper-V within them, as a layer 2 hypervisor.The scenario is we have a few Windows 2016 VMs running on ESXi at the moment and each VM has the Hyper-V role installed in Windows 2016, providing containers for Docker.We want to move the VMs to our Nutanix cluster but running Hyper-V within a VM is not a supported type of nested virtualisation.Support say there are only 2 types of nested virtualisation supported: Credential Guard and WSL2.Docker is able to use WSL2 for containers as an alternative to Hyper-V but our problem is we need to stick to Windows because our apps are coded for Windows and our Dev team are not keen on re-writing everything!I’m looking for an unofficial workaround, is there a way to force AHV to allow in-guest layer 2 hypervisors to run? Its possible on ESXi, it feels like there should be an option in the host’s BIOS to enable compatibility.Any ideas would be

Regarding the last_update_time not being updated for VMs

Hi everyone, We’re using v3/vms/list endpoint to get the information for the VMs. We’re getting last_update_time in the response. Truncated response for a VM:"metadata": { "last_update_time": "2023-06-08T10:49:22Z", "kind": "vm", "uuid": "cff450d3-dd1f-4d7d-9651-9b38164cb7e5", "creation_time": "2023-06-08T10:49:01Z"}I was expecting that if we change any properties of the VM like RAM, Disk Space, etc then last_update_time should get updated. However, irrespective of the value that we change, the last_update_time doesn’t get updated. Additionally, there is no time field which we can use to track the VM updation. Is this an expected behavior? Please let me know if I am missing something.

Assistance installing community edition for testing

Hey Team,I need a little bit of assistance here. I am new to Nutanix and currently attempting to deploy the community edition for some testing. However, I’ve been following several different guides out there and not having much luck.Installing on VM using ESXi 7.0 (VM version 17). I created new VM w/ Centos 7 compatibility and loaded the ISO.ISO was downloaded from here:https://next.nutanix.com/discussion-forum-14/download-community-edition-38417And md5sum matches.The ISO loads and boots up. I then go through the CLI UI installation and get past to the last screen where it should start installing but then get an error that I need help troubleshooting:Last Screen:Then the Error right after the previous screenshot:Looking at the error, there is reference to minimum requirements but I’m pretty sure I meet them on this VM but if this is what it is, then I can look at a newer beefier server to test on:8CPUs24GB of MemorySata1 20GbsSata2 50GbsSate3 50GbsAnyone seen this error before?

Regarding the pagination not working for v3 hosts endpoint of Prism Central

For our development work, we are using /v3/hosts/list endpoint. As per the specs, we want to use length and offset for pagination to fetch large number of hosts. We tried using it as follows:curl --location --request POST 'https://<host>:9440/api/nutanix/v3/hosts/list' \--header 'accept: application/json' \--header 'Content-Type: application/json' \--header 'Authorization: Basic abc' \--data-raw '{ "kind": "host", "length": 1, "offset": 9}'However, length and offset params doesn’t seem to be working. It returns all the hosts (2 in our case) irrespective of the params passed. Also, we used the same params in /v3/vms/list and they are working as expected. So, wanted to know if this is expected or is this an open issue? Is there a way to get all the hosts through Prism Central (v3) APIs?

What is ICAP and integration with Nutanix files

ICAP stands for internet content adaption protocol is an open standard being adopted to connect devices to enterprise-level virus scan engine . same way with the nutanix files is to enable communication with external servers hosting third-party anti-virus software to scan inbound data (files) in transit via Secure Proxy before sending it to the backend destination server.ICAP WORKFLOWThe ICAP service runs on each Nutanix Files file server and can interact with more than one ICAP server in parallel to support horizontal scale-out of the antivirus server. The scale-out nature of Files and one-click optimization greatly mitigate any antivirus scanning performance overhead. If the scanning affects Nutanix Files FSVM performance, one-click optimization recommends either increasing the virtual CPU resources or scaling out the FSVMs. This feature also helps both the ICAP server and Files scale out, ensuring fast responses from the customer’s antivirus vendor WHY Nutanix files integration with

Change Nutanix AHV NIC From access Mode to Trunked Mode

Trunked Mode allows multiple VLANs on a single NIC for VMs that are VLAN aware.by default, NIC cards are in access mode.mode can't be changed from the UI (Prism) and the solution is to update from CVM acliyou can also covert exiting NIC card to Trunked Mode however based on my experience best and easy way is to add a new cardStepsSSH CVM acli <acropolis> vm.get VMNAME copy information in notepad nutanix@CVM~$ acli vm.nic_create <vm name> network=<network name> trunked_networks=<comma separated list of allowed VLAN IDs> vlan_mode=kTrunked example:-vm.nic_create VT-LAB-1 network=NETWORK0 trunked_networks=2021,2022 vlan_mode=kTrunkedWHY Trunked is Required Above Setting is required when the virtual machine needs to create multiple networks on a single interface. in my case it's WAF devices that are configured for multiple VLANs, each VLAN is associated with a different kind of applicationif you want to add more VLANs run the belowvm.nic_update TT-WAF-01 00:68:8

Cross Hypervisor Disaster recovery ESXi To AHV or AHV to ESXi

Cross hypervisor disaster recovery (CHDR) provides the ability to migrate the VMs from onehypervisor to another (ESXi to AHV or AHV to ESXi) by using the protection domain semanticsof protecting VMs, generating snapshots, replicating the snapshots, and then recovering theVMs from the snapshotsKey notes install and configure NGT on all the VMs When you recover VMs from the AHV hypervisor on the ESXi hypervisor, the VMs come up with E1000 NIC attached by default. However, if you want to bring the VMs up withVMXNET NIC is attached, you must install VMware Tools Static IP address preservation is not supported for CHDR workflows. If a VM has an astatic IP address configured, you must manually reconfigure the VM IP address after its recovery on the target site. Hypervisor-specific properties like multi-writer flags, independent persistent and independent non-persistent disks, or changed block tracking (CBT) is not preserved in the CHDR operation RequirementsNutanix supports only VMs with

Nutanix Datastore Online and Accessible. Unable to Mount to ESXI

We are running a Nutanix environment with 3 CVM nodes (A,B,C) on 3 separate ESXI hosts (7.0 Update 3) with 3 IPMI configurations using vCLS. Originally, Node A failed during an FSM upgrade and was unable to talk correctly to our Houston Datastore (MCQ-HOU). In doing so, there was no snapshot and we were unable to roll it back. We were currently in the midst of attempting to create a new node on the same ESXI host (.204) through Nutanix Prism but when searching for any existing or accessible hosts it does not find any of them and we are unable to create a new one. We attempted to shut down the cluster, unmount the Datastore on the broken node and re-mount it once we were able to clone a functioning node and change the configuration. In doing so, we are now unable to mount the datastore with the following commands and were presented with an error:esxcli storage nfs remove -v 192.168.5.2:MCQ-Hou Unmountesxcli storage nfs add -H MCQ-Hou -v MCQ-Hou -s 192.168.5.2 MountPlease see the VMkerne
