Guided Script for sysprep on clones or template-based deployments customization

New to AHV, just installed this week.  I have using VMware since version 2.5. Trying to deploy AHV Windows VMs from template and from AHV VMs.  On both methods I get guest customization options using sysprep.  I have been choosing “Guided Script” and filling out the fields for User Name, Password, Local, and Host Name.  I leave the license key blank becasue we have enterpise licesing which is assigned when teh VM is joined to the domain. So far, evertime I have tried the host name does not get updated to match the Host Name I entered for the guided script.  Also, in VMware guest customization you put what you want the password to be after sysprep.  Fr this one is it asking for the current Administrator User/Password, or one to be updated or created by sysprep?

Change NTFS disk allocation unit size from 4k to 64k

We have a (older) Windows 2012 R2 VM with a OS Disk and a Data Disk (scsi.0 and scsi.1 respectively) running on AHV / AOS 5.20.4.6 LTSThe data disk (scsi.1) was originally created with 4kb allocation unit size (no NTFS disk compression is utilized) and this disk has reached it’s maximum size under NTFS of 16TiB. It’s also 96% full… 😟The custom application is such that mount points won’t work. It was suggested to see if perhaps Acronis Disk Director could safely change the drive’s allocation unit size from 4k to 64k (and preserve the data). To my knowledge formatting a drive is the only way to accomplish allocation unit size changes...Is changing the allocation unit a supported operation?Has anyone successfully made such a change?

Nutanix Node Expansion Queries

Hello Guys, I have a scenario where the current nutanix environment NX-1065-G7 AOS version is 5.20 LTS and AHV version is 20201105.2030 and we are adding new node NX-1065N-G8 to the cluster. My plan is to upgrade foundation and NCC of the cluster to latest version and then image the new node with AOS and AHV version the same as in the current nutanix environment.What are the caution points I need to be aware while configuring the node and adding to the cluster?what are the risk factors involved?

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

Move VMware vCetner Server Appliance to Nutanix Cluster

I have two clusters managed by a vCenter Server Appliance (v7.0). One of those clusters is a Nutanix cluster. All hosts in all clusters are running ESXi 6.5. There is no storage shared between the clusters. What is the best and easiest way to migrate the vCenter Appliance to the Nutanix cluster. I’m already configured to move other VMs using Enhanced Shared-Nothing vMotion and that is working fine. Can I use the same method to live migrate the vCenter Appliance to the Nutanix cluster? If possible to live migrate, should I set DRS to manual and disable HA on all clusters before live migrating the vCenter Appliance?

Can I migrate from cluster memory usage 90% to another host?

Currently, the Nutanix cluster consists of three nodes.The Prime Element has 90% Cluster Memory usage.Data Resilience Status is indicated by "OK". I'm trying to add more memory to the node in this environment.If you change a node to maintenance mode for memory DIMM expansion, the VMs on that node will be migrated to another node. The average usage rate of re-memory is over 90%, will the migration be successful?The Fault Tolerable of Data Resilience is all "1"... I don't know for sure. I wonder if live migration is possible in this environment, and if not, do I need more nodes or downtime?

Schedule Automated VM Power State

I hate to duplicate questions, but the original was closed and I have yet to see an answer. Is it possible to schedule automated reboots/shutdowns with an AHV? Similar to what you can do in VMware vSphere with Scheduled Tasks: How to schedule a VM power state with AHV

Map AHV VM Drives to OS

I have started to code this but thought maybe someone might have already completed this. My issue is I have a windows server in AHV with 10 disk drives. When I get a call from my windows team to expand a drive they will give me the drive letter. However I cannot use that to map back to Nutanix AHV. So outside of coding a tool that will map these 2 systems is there a way to correlate what drive is what? I do not want to have to log into a VM every time I get this request if possible.

Adding NGT with missing CD-ROM

We migrated many guests from vmware esx to Nutanix sans cd-rom. They are all in production now. But we find that many of them need NGT for better backups. The bus type is SCSI. To add NGT you need CD-ROM but we have none. The NGT install looks to be unique per guest with special certificates injected into the CD-ROM. We dont want the extra CD-ROM hardware always lingering so we remove it after NGT install.Consider this a plea for help, a gripe and a feature request.To add NGT, we must shutdown the guest. Add CD-ROM (because it wont let us hot-add). Boot, install NGT. Shutdown, remove CD-ROM and boot.Why no hot-add capability?Can someone offer a simpler workflow that only involves one reboot?Why not make the ISO available to the guest in additional ways like a SMB share or Web\SSL download link.Why not add a feature to the NGT install that allows any guest to negotiate the needed certificates with the cluster on the fly?If any of these problems have a solution, please update the kb’s an

Mount External Datastores to VMware on Nutanix

It’s unclear to me whether or not it is supported to mount datastores, whether NFS or iSCSI, from external sources onto VMware hosts running on Nutanix for VMDK storage for VMs. I apologize if this has been answered before or clearly stated in docs somewhere.

AHV Windows Licensing

Can someone chime in on how Licensing woudl work when using AHV? For example, we currently have Windows 2012R2 Datacentre edition on each host and we have the ability to have unlimited licensed Windows Servers virtualised. I know that AHV doesn't require a license but does that mean that a license for each Widnows Virtual Server will need to be purchased hence invalidating our Datacentre license???

Found some VMs with IDE bus type for disks, why?

Hello everyone,Someone before me in my current job created a couple of VMs in AHV with IDE bus type for their disks instead of SCSI. Just a quick glance of the documentation I found this:AHV does not leverage a traditional storage stack like ESXi or Hyper-V. All disk(s) are passed to the VM(s) as raw SCSI block devices. So my question is, why would someone decide to create IDE disks? Am I missing something? I know it’s common practice for CD-ROM drives, but not storage disks. No wonder I noticed a really bad performance on those servers recently.

Foundation and Phoenix

Hi,I have a confusion between the role played by foundation and phoenix, during a LCM firmware upgrade, moreover I am not finding a deep dive article explaining this end to end:1. Once the phoenix iso is created and mounted to the host along with the upgrade bundle, Can phoenix run independently and complete the upgrades or needs help from foundation for performing some tasks like host reboot ?2. During LCM upgrade, since the node undergoing upgrades, will have all VMs powered off including the CVM, will it take help from a remote CVM foundation to orchestrate the upgrades on this host ?3. Putting host in maintenance mode is taken care by LCM or foundation service?4. Can you please give a high level working of the phoenix mechanism, since the hypervisor installer itself is a separate iso, which needs to be mounted, just wondering how phoenix handles multiple iso, does it mount simultaneously with the upgrade iso?

Decoding LEDs and their blink states

Did you ever wonder what the blinking green light or the solid amber light on the LED of the network card indicates?Are you confused between a blinking green light and a solid green light? Different NIC manufacturers use different LED colors and blink states. Not all NICs are supported for every Nutanix platform. To know what each blink state means on the different manufactured LEDs, check out this article here.

Enabling or Disabling Console Support for vGPU VMs

Enable or disable console support for a VM with only one vGPU configured. Enabling console support for a VM with multiple vGPUs is not supported. By default, console support for a VM with vGPUs is disabled.To enable or disable console support for each VM with vGPUs, do the following: Run the following aCLI command to check if console support is enabled or disabled for the VM with vGPUs.acli> vm.get vm-nameWhere vm-name is the name of the VM for which you want to check the console support status.The step result includes the following parameter for the specified VM:gpu_console=FalseWhere False indicates that console support is not enabled for the VM. This parameter is displayed as True when you enable console support for the VM. The default value for gpu_console= is False since console support is disabled by default.Note: The console may not display the gpu_console parameter in the output of the vm.get command if the gpu_console parameter was not previously enabled.
