slow performance with Citrix MCS

Hi, we have a new Nutanix Cluster with three nodes. Now we will move our citrix farm from VMware to Nutanix.But on Nutanix the VMs much slower as on VMware. We use publish desktops with Citrix MCS an Fslogix.Login with VMware takes 15 seconds with Nutanix more that 50 seconds.The Nutanix Hardware much better then on Vmware.So we don‘t understand why it is so much slower.Also we use the Best Practice Guide from Nutanix for Citrix MCS.so have anybody an idea, why Citrix is slower on Nutanix and what we can do to speed up the system?

Error in API Reference - Python on ntnx_vmm_py_client.AssociateVmCategoriesParams()

Hii don’t know where to report this(no feedback menu on Redocly), but since people may encounter this issue too, i guess they may land here while searching for a solution.As of 11 April 2025, there is an error in the documentation of APIv4 (python version) with regard to associating categories to a VM.The page is here: https://developers.nutanix.com/api-reference?namespace=vmm&version=v4.0The example code says at one line: associateVmCategoriesParams = ntnx_vmm_py_client.AssociateVmCategoriesParams()well, upon investigating the ntnx_vmm_py_client libraries, i’ve noticed that the class AssociateVmCategoriesParams is imported using AS, therefore with different names depending on technology, as follows: from ntnx_vmm_py_client.models.vmm.v4.ahv.config.AssociateVmCategoriesParams import AssociateVmCategoriesParams as AhvConfigAssociateVmCategoriesParamsfrom ntnx_vmm_py_client.models.vmm.v4.ahv.config.DisassociateVmCategoriesParams import DisassociateVmCategoriesParams as AhvConfigDisas

Category on PCVM

It seems to be the case that no category and value can be applied to the PCVMs.Is that true and if so, will that be altered in the future?If not this causes some unexpected challenge. Thank you

Volume Group resilience

We have a couple of VG’s with 20’ish disks in each, on our 4 node AHV (AOS 6.10.1) cluster. 1 VG is shared with 2 SQL boxes in prd and the other with 2 SQL boxes in our pre environment.  I was patching the environment today with a BIOS update so the hosts needed to be restarted for the update to apply, I had a report from our DBA that they lost connection to the shared disks from the SQL boxes.  What is the expect behavior for VGs with shared disks when a host is unavailable due to a planned or unplanned outage?

AHV/ PC snapshot

Hi, Hello,Am looking for help on snapshots and reverting to recovery points. Is my PC GUI fully equipped to handle snapshots and restore to snaps? sometimes for some vms it works and it doesn't for for few other vms. as a workaround we were asked to do it via CLI. though this may get fixed in later versions, any RCA on why this happens? am on AHV 6.x version.Are these snapshots work exactly like the snapshots from VMware or is it different?

non_migratable_vm_action what is the difference between block and acpi_shutdown?

Hi,I am confused by information in the prism central infrastructure guidePrism pc.2024.3.1 - Defining Behaviour for Non-migratable VMs (GPU/CPU/PCI/Host Affinity configured VMs)non_migratable_vm_action: By default, this parameter is set to block, which means the non-migratable VMs are shut down when you put a node into maintenance mode. For more information on non-migratable VMs, see Non-Migratable VMs.If you want to automatically shut down such VMs for the duration of the maintenance mode, set this parameter to acpi_shutdown.It seems both settings result in shutting down the VMs. Am I missing something, or is there an error in the documentation? I assumed block would prevent maintenance mode and keep the VMs running.Same information in the AHV guideAHV 10.0 - Putting a Node into Maintenance Mode using CLI

Storage tiering for QLC SSDs

I am considering building a cluster that will use a mix of TLC and QLC NVMe SSDs. I assume that Nutanix will put all of these drives into the SSD-PCIe storage tier and every disk will be a member of the same tier. Since QLC SSDs have lower performance and lower write endurance than their TLC, MLC, and SLC counterparts, it would be advantageous to use storage tiering to encourage cold data to reside on the QLC media and hotter data to reside on the more performant drives. Is there a supported method for this in non-community edition clusters? It would be relatively straightforward to manually change the tier-name for the QLC drives to SSD-SATA, but is that a supported practice?

Deploying VMs from a template using Terraform

Hello everyone, I am trying to deploy VMs from a template by using terraform ( nutanix_deploy_templates_v2 ). I have located the UUID of the template i want to use and terraform plan works with no issues. When I go to apply the changes it errors telling me the template is not located on that server. I have quadruple checked the addresses etc and even had it peer checked so we are happy with the code. Has anyone else experienced this or am I just being dumb?Any help would be appreciated - cheers
