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.

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

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.

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.

GPU Pass-Through for Guest VMs

AHV hosts support GPU pass-through for guest VMs, allowing applications on VMs direct access to GPU resources. The Nutanix user interfaces provide a cluster-wide view of GPUs, allowing you to allocate any available GPU to a VM. You can also allocate multiple GPUs to a VM. However, in a pass-through configuration, only one VM can use a GPU at any given time. Host Selection Criteria for VMs with GPU Pass-Through When you power on a VM with GPU pass-through, the VM is started on the host that has the specified GPU, provided that the Acropolis Dynamic Scheduler determines that the host has sufficient resources to run the VM. If the specified GPU is available on more than one host, the Acropolis Dynamic Scheduler ensures that a host with sufficient resources is selected. If sufficient resources are not available on any host with the specified GPU, the VM is not powered on.If you allocate multiple GPUs to a VM, the VM is started on a host if, in addition to satisfying Acropolis Dynamic Sched

Virtual Machine Memory and CPU Hot-Plug Configurations

Memory and CPUs are hot-pluggable on guest VMs running on AHV. You can increase the memory allocation and the number of CPUs on your VMs while the VMs are powered on. You can change the number of vCPUs (sockets) while the VMs are powered on. However, you cannot change the number of cores per socket while the VMs are powered on.You can change the memory and CPU configuration of your VMs by using the Acropolis CLI (aCLI), Prism Element (see Managing a VM (AHV) in the Prism Web Console Guide), or Prism Central (see Managing a VM (AHV and Self Service) in the Prism Central Guide).Memory OS Limitations On Linux operating systems, the Linux kernel might not make the hot-plugged memory online. If the memory is not online, you cannot use the new memory. Perform the following procedure to make the memory online. Identify the memory block that is offline.Display the status of all of the memory.$ cat /sys/devices/system/memory/memoryXXX/state Display the state of a specific memory block.$ gr

Symantech Messaging Gateway AHV

I downloaded symantec messaging gateway (brightmail) ova file. I uploaded the vmdk file as an image on my prism. I created a virtual machine and attached the disk. but it is not booting. virtio diriver is not installed., i tried to install it and it is not installed. because brightmail root access is restricted. I never found a way to install it. I talked to symantech support, the result; they said only vmware, hyperv support. I tried many ways; ova, backup/restore.. but without success. I can't run brightmail on ahv. it doesn't boot. I seek help from those who have succeeded in this matter. thank you.

How to open nutanix case for HPE DX380 Hardware

We have 3 node HPE DX380 deploy nutanix recently.After 2 - 3 days, i saw the physical disk show bad disk suddenly and no flush light in physical disk LED light. When i login iLO port, the storage is good and no error. When i login PRISM, look the disk is Red and show “The drive has failed”. When i unplug it and plug it again, and re-partition it, seems back normal, but i concern the new server have this error suddenly so want to create nutanix case, but when i create case with input HPE serial number, it is not allowed, so i would like to ask how to create Nutanix case for HPE DX380. Many thanks.

AHV VM FT

Is there a way to implement FT at the VM level (i.e. similar to how it’s done on ESXi) on AHV. I’ve seen a couple of different posts that point to preferred technologies like software HA and AGG (not that I know what/how to do this) but we currently have the requirement for a legacy type VM to be always available and the only method we can do that at the moment \is having ESX as the hypervisor. This is for a future project, so am not locked into current versions. Cheers. Paul

Real cost of AHV

Hi fellas,Does anyone have a clear answer of what is the real cost of AHV? I’m told that AHV is free but is this referring to only Nutanix Community Edition? What about AOS? when purchasing a Nutanix node/block/cluster, these come pre-installed but the cluster essentially has no ‘smarts’ without the CVM which is AOS.Referencing this Licensing Quick Reference Guide, it looks like AHV is included with AOS but AOS’ licensing metric is charged per node. Am I reading this correctly?Is it possible to run AHV without AOS? Thanks,JS
