Can't get Credential Guard to work

What is the status of Credential Guard on Nutanix VMs? We are running AOA 5.20.I have created a new VM with UEFI, Secure boot and Credential Guard enabled, but I can’t get it to work. Credential Guard is enabled with GPO, but still will not run. When I look at device security, it says “Standard hardware security not supported” and there is no compatible TPM shown in tpm.msc.The OS I’m testing it on is Microsoft Server 2019.

VMs on seperate subnets

We have a UTM with 6 interfaces that go to separate subnets. Each subnet has a ToR Switch. The UTM handles the routing. We are installing a new Nutanix 4 node Block and virtualization physical servers. Assuming that we have 6 physical servers and each server is on a separate subnet, what would our network diagram look like if we included the Nutanix Block? Would we need another switch that has the 6 subnets vlanned, ie: 1 connection from the block and then based on the traffic destination send the traffic out through the vlan port to the ToR switch in the destination subnet?

VM is on HDD or SSD?

Hi Folks,I have some SQL servers running on Nutanix without using ‘Flash’ mode for those. I am facing disk latency alerts for vmdisks on those SQL server VMs. Is there any way to identify if the VM disks are on HDD or SSD?

P2V SQL servers to Nutanix

Hi Folks,I want to virtualise 2 SQL servers on Cisco UCS hardware to Nutanix. I found references for Xtract for DB, however it seems it is a legacy tool as I am not able to get much information on it. Nutanix ‘Move’ seems to be used for VM migration.On Nutanix I have ESXi, so i know we can use ‘Vmware Converter’, but I would like to know if there is any solution from Nutanix for this.Can some one please guide me about the ways I can achieve this P2V of SQL servers?

Data service IP vs direct attach when connecting Volumes

When I searched the documentation, it was said that scsi-3 pr3 is supported when attaching volume from AOS 5.17.my curiosity1. In versions prior to 5.17, when allocating a shared volume for vm redundancy configuration, if you use Attach instead of using iscsi-initiator, does it not work?2. Considering I/O speed and stability, which do you think is better, mounting a volume through iscsi-initiator or connecting to a VM as a direct attach?

Solution microVMs and nested virtualization

Is there the possibility of using the microVM concept in Nutanix? Are solutions like firecracker (https://firecracker-microvm.github.io/) possible with Nutanix?As I understand it is not possible to nested virtualization with Nutanix (https://next.nutanix.com/server-virtualization-27/nested-virtualization-33423), so is there any provision for a feature that enables the use of microVMs with Nutanix?

Virtual Machine High Availability

Virtual Machine High Availability (VMHA) ensures that VMs restart on another AHV host in the cluster if a host fails. VMHA considers RAM when calculating available resources throughout the cluster for starting VMs. VMHA respects affinity and anti-affinity rules. For example, with VM-host affinity rules, VMHA does not start a VM pinned to AHV host 1 and host 2 on another host when those two are down unless the affinity rule specifies an alternate host. There are two VM high availability modes:  Default: This mode requires no configuration and is included by default when installing an AHV-based Nutanix cluster. When an AHV host becomes unavailable, the VMs that were running on the failed AHV host restart on the remaining hosts, depending on the available resources. If the remaining hosts do not have sufficient resources, some of the failed VMs may not restart.  Guarantee This non-default configuration reserves space throughout the AHV hosts in the cluster to guarantee that all VMs can re

VM creation with ACLI

So I use the following script to create a VM. I actually have a small batch file that opens putty, logs into a CVM, prompts me for the $name and then runs the script below. The image is one I made, then sysprepped and uploaded as a disk image.Everything works great except that when I then open the console it goes through the Windows setup. I have an Unnattend file but I am unsure how to use it with my script. If I go through the GUI to create a VM I just point it to the unattened file in our file share.Is there a way to attach the sysprep file? I thought it might be a parameter vm.disk_create but I am not clever enough to figure that part out and thought maybe someone else smarter could help. First world problems I know but it could help save me 30 extra seconds of not having to type the admin password in and set the keyboard settings etc.#creates a vmacli vm.create $name memory=$mem num_cores_per_vcpu=$core num_vcpus=$vcpu uefi_boot=TRUE &&#Create C:acli vm.disk_create $name c

AHV image service - uploading not fast enough

Do you know guys a way to speed up uploading large image files (vhdx etc) to a Nutanix container? Using browser or winscp we got maximum 180GB/hour (using a windows VM with direct connect to CVM network, no routers/firewalls). Any idea?

Default Storage Container for new VMs built through RestAPI?

We automate the creation of new VMs in our AHV cluster using RestAPI calls and JSON provided VM specification (generated by script etc). Nowhere in our provided JSON do we specify the storage container that vdisks should be created in, but all new VMs have their storage allocated inside ‘SelfServiceContainer’. Wondering if SelfServiceContainer is somehow configured as a default inside AOS - as I would like to change this to a different container if such a config exists? Now I know that I can specify the storage container inside the JSON I provide for each VM creation (and this might be the only way I achieve this), but I am trying to understand if there is someway of configuring a default storage container inside AOS?Thanks in advance, Paul

Error creating VM

Hi - I’m having an issue with a new installation of Nutanix on AHV (single node cluster) that I’m hoping someone hear can help with.Basically, using Prism, when I attempt to create a new VM the process fails with the error “VM with ID ‘*********’ was not found”. However, if I attempt to add a VM without a new disk, it successfully creates the VM but I can’t add a disk to it, error “Operation Failed: InternalException”.I’ve been able to upload my ISOs for installation etc. and of course the CVM is seemingly working fine. Any ideas what could be wrong? Many thanks.

Self Service VM Customization

I want to introduce Self-Service VM operations via Prism Central for our end-users (do not have CALM). So, I’ve used cloud-init (Linux VMs) and cloudbase-init (Windows VMs) along with customization code (Python) to deliver this Self-Service VM provisioning experience. You may refer https://github.com/cybergavin/nutanix/tree/master/self-service for details of this set up. Any feedback always welcome. Sorry if the code isn’t too pythonic as I’m a python newbie.

Nutanix CVM - diskspd

I’m new to Nutanix and we have a Nutanix cluster online. For testing purposes I’m running diskspd test in a VM.I’m running some diskspd test with identical VM configs in several enviroments 3-tier Hyper-V/ VMware and HCI Nutanix AHV.Why is it that running a test with -Sh flag (no software/hardware cache) gives almost 10 times lower results in Nutanix compared to other platforms? Without -Sh flag Nutanix is running test with higher results compared to my other testing platforms. Is it because of how CVM is designed to work? I’m just trying to understand.

Determining appropriate methodology for cpu over subscription

We are new to Nutanix. We are migrating from ESXi to AHV.  We currently have some level of CPU oversubscription in place on ESXi.  We anticipate the need to oversubscribe CPU on some clusters and I am looking for ways to do this safely.  I’ve looked in the Best practices guide but there was very little there.  Any help would be appreciated.
