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 Hyperviosr 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

AD User unable to access VM console on Prism Central

AD user is having trouble accessing the VM console on Prism Central. They can log on normally to Prism Central. After clicking the VM, only a blank page with the name of the VM appears instead of the console. There is no "FAIL" status after the health check that I ran. Additionally, I verified that RBAC allows users to access the VM console.After PC was updated to version pc.2022.6.0.3 with LMC 2.5.x, PE software was upgraded on AOS 6.5.2.5, and AHV 20220304.342, and this problem appeared. Is there a chance that this problem can be resolved?

Sysprep behaviour with/without Prism Central guest customization option

Hello I'm currently working on a Windows Server 2022 image these days, and something got weird on the 3 below scenarios1) From PC - deploying a new VM from image by specifiying guest customization with only username and password Sysprep seems to works but logs are quite short 2) From PC - using a unattend.xml in the guest customization settings that only change username/password Same result as you can see below 3) Manually from inside the VM, launching sysprep.exe /generalize /reboot /oobe Logs are very long (file is like 145ko vs 5ko for 1) and 2) and a lot more stuff seems to be done rather than 1) and 2) , as you can see below My questions are :Does the guest customization from PC is really working ? what should be the best way to sysprep a VM from PC ?  Thanks a lot for your help :)

How to properly deal with UEFI and Windows Server 2022 ?

HiAs Microsoft advise / Windows Server 2022 isn’t Legacy BIOS compatible anymore, i have to set up a brand new template using UEFI.However, if i tick “EFI” and Secure Boot from VM configuration or not, I can’t boot on my ISO at all. It still go to EFI Shell or in the UEFI Menu.I also tried to update VirtIO drivers directly into my Windows image (on install.wim and boot.wim on all indexes) but i can’t go so far in the installation part. Does anyone was able to use EFI settings with Windows Server 2022 ? If yes, what was your settings  ?
