AHV Virtualization

Hi all, after migrating SQL Server(2K12) from ESXi to AHV, all schedule jobs whithin SQL server are taking much longer. any idea what could lead to this behavior?

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.

I wanted to check in to see if anyone has done a Cisco WLC with AHV, we are migrating from VMWare and currently use VGT (VLAN 4095) but it doesn’t look like there is an equivalent. Has anyone been able to get this working?

There is a way to collect virtual machine performance from Prism Central using v3 RESTApi ?Or my only way is to using Prism Element via v1 RESTApi ?

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?  

In waiting for possibility to deploy VMs from templates with Ansible (see https://next.nutanix.com/ahv-virtualization-27/how-deploy-vm-from-prismcentral-template-with-ansible-nutanix-module-41800), i’tm trying to use cloning, see playbook below.  The demo playbook with same parameters works fine to get cluster info for "{{ prism_cluster }}".The cloning fails with error  :KeyError: 'cluster_reference'What is missing in playbook ?Thx  

As stated in the question, how do I create a template from a VM in AHV?And how do I use the template to create a VM?

 As shown in the picture here, my VM’s UUID is not completely displayed. How can I see the full UUID?Or is there any other place I can view the full UUID?

Hi All ,I had created two VM’s of RHEL7 and RHEL8 in AOS 6.5.2 and while validating the SCSI id’s for disk using lsscsi --scsi_id command for RHEL7 am getting vendor specific SCSI_ID identifier and for RHEL8 am getting NAA scsi_id identifier. Is it possible to get the vendor specific scsi_id identifier for RHEL8. Rhel7 SCSI_ID:   Rhel8 scsi_id:  Types:  ThanksTeja K 

I am getting this warning on my Prism CentralWARN: VM ad_linux_test has 1 snapshot(s) that have existed in the storage for more than 7 days.Refer to KB 4273 (http://portal.nutanix.com/kb/4273) for details on aged_entity_centric_third_party_backup_snapshot_check or Recheck with: ncc health_checks data_protection_checks protection_domain_checks aged_entity_centric_third_party_backup_snapshot_check I dont see any VM by name ad_linux_test in my inventory.I have also checked Prism Central UI -> Virtual Infrastructure -> VM Recovery Points -> Select the VMnothing in that  I am not sure how to cleanup this snapshot. I dont want to extend the warning threshold as per the KB 4273

HelloThere are sites that have VDI configurations.Files configured on the above site.There is personal storage allocated for each user using Files.Is there a way to recover only one piece of personal storage other than a full backup of Files using Data Protection?

Hello, under storage details I have had a Snapshot listed using 1.36TiB for a few weeks now and I’m not able to locate where it is. Is there any commands that can help me find it?  acli snapshot.list does not list any   

Hi, I am going to deploy with three node cluster and while doing the node imaging getting dependence issue can any one help me.

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

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 (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

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

Hi guys, i need imformation about max nodes per cluster for one of our implementation.I cant find any official information for max cluster size.Thanks

Recently i have Expanded the cluster with two node and i have created two vms in the same network range but two vms are not reachable in the Nutanix cluster please help me anyone.

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?

I have just installed the module Nutanix for Ansible. The demo playbook works fine.https://www.nutanix.dev/2022/08/05/getting-started-with-the-nutanix-ansible-module/But I can’t find in the module documentation how to deploy VM  from a VM template just like we do with https://docs.ansible.com/ansible/latest/collections/community/vmware/vmware_guest_module.html ?Thx

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 :)
