"Zombie" VMs... Shouldn't Citrix be catching these? I find it hard to believe Arithmos is having a blip on a single VM on a whole cluster for 3 hours... Have several "Zombie" VMs this morning ranging from 1205AM 725AM this morning... I have noted an uptake in Zombie activity since VIRTIO 1.2.3, was going to upgrade to 1.2.4, however there's also a good chance there's guest-level issues... Curious if any Citrix-Nutanix SMEs have any thoughts on this one where Citrix isn't getting the memo and Nutanix shows CPU activity halted, or conversely, any suggestion mitigations... Example hard reboot set on the AHV plugin?

We're looking at upgrading one of our clusters to AOS 7 to support live migration of vGPU-enabled VMs. This will be our first AOS 7 cluster. Anyone doing this today? Anything that should give us pause?

Did anyone have a successful upgrade of NTNX Community Edition AOS to 7.x?

I have a large number of VMs that are built on an incorrect storage container. I'm moving them to a different one via Prism Central, but it limits to 3 at a time per cluster. Is there a way to create a playbook or a queue to move more than just 3 (and avoid having to select them individually?)

Running CE with AHV 10.0.1 and AOS 7.0.1. Needed to replace a hard disk and we improperly assumed hot plug would work. Removed the disk afterwards in Prism Element, and the CVM on that node went offline. Found this blog article (thanks Sean) and followed the steps. When I edit the cvm_config.json and reboot, virsh list -all shows no vms. If a restore the backed up copy of the cvm_config.json, the CVM reappears in the "shut off" state. Does anyone know any other articles etc. that can assist me in editing the file correctly?

I'm seeing an issue with MCS provisioned persistent machines being created with the main disk on the selfservicecontainer rather than the container specified. The source image/snapshot is on the desired storage container (granted I moved it there as it was on the selfservicecontainer originally) and the identity disk is getting created on the proper storage container. Is this an artifact of the source machine originally being on the selfservicecontainer?

I need to move our Gold image VM from one cluster to another - easy enough with a protection domain (can't do it with PC due to reasons). However, that only brings the current VM, not the previous snapshots. Is there an easy way to bring the snapshots along as well? My thought currently is to revert the image to each snapshot desired to be kept, and protection domain snapshot it and then restore as a separate VM in the unlikely event we need to use it. Was hoping there would be a cleaner way to move the VM along with all of its snaps.

Has anyone tried to run a Nutanix Vm and load the IGEL software? I am trying to setup a lab device to test with and Nutanix runs our Lab. When I mount the ISO I get to the Standard Installation + Recovery screen and choose that, it then boots to this screen and I cannot see anything. Is it possible to do this?

Attempting to create a Windows 11 VM on my new Nutanix CE lab that I recently stood up, which runs on generic NUCs with Intel CPUs. I ran into the e1000 nic issue, so used acli to add an Intel NIC and also the vTPM, and checked machine type is set to Q35. If I boot the machine in UEFI mode, and untick Secure Boot the VM will boot and starts setup, but states system requirements aren't met (which you'd expect). If I tick the Secure Boot setting, the VM boots but hangs at the "Press F2 for EFI" screen. I haven't found any workarounds to this - has anyone run into this and know a resolution?

Next challenge. After updating everything to latest versions through LCM (AOS 7.0.1.6/AHV 10.0.1.1), I can no longer boot any of my VMs at all. The issue looks to be same as this one described in the forum post here, I fixed the maxmem issue by editing the qemu-kvm-frodo script but the VMs then hang at the console with "Guest has not initialized the display (yet)". I am wondering if something in this latest AHV version has removed support for my CPU (Intel Core i9-11900H). VMs won't power on - QEMU error | Nutanix Community

I have a small 4 node cluster that has crossed the storage threshold for node failure tolerance. When the cluster was built, ALL of the persistent VDIs were created on the self service cluster with no compression or dedupe. In order to prevent excess cpu utilization, I've been moving VMs to a different container that has compression/dedupe enabled. This is very, very slow as I can only do 3 VMs at a time, and it takes hours to complete. Can I safely enable post process compression (and dedupe ideally since it's all persistent vdi) on the self service container and have it compress the data without impact to the cluster? There are about 130 VMs in the container, with ~50GB of data each. If I can do it 'safely while monitoring' what would be my 'stop it' fix if it does begin impacting things? This cluster is for RPA bots so it stays around 40% cpu all the time with normal load, so there's no benefit to doing it on a weekend or during off hours.

For those with Nutanix CE labs on non-Xeon CPUs, I got a response on the forums re some of the recent changes. It's a long post but here is some of the key info. Full post at VMs won't power on - QEMU error | Nutanix Community What Changed in AHV 10.x? Nutanix AHV 10.x Enforces "Server-Class CPU Compliance" Starting with AHV 10.x, Nutanix hardened the VM launch pipeline to: • Explicitly validate CPU capabilities against enterprise server-grade specs (e.g., Xeon or EPYC-class), • Enforce minimum physical address bits (typically ≥ 46) during VM memory allocation. This is not a documented behaviour change in public-facing PDFs, but it's implied in internal support KBs and developer-level discussions. Consumer-grade Intel CPUs (like your i7-10710U) only expose 39–42 physical address bits depending on firmware microcode. AHV 10.x+ now expects 46–52 bits, in line with Xeon-class processors. Root Technical Impact In AHV 10.x: • qemu-kvm now fails fast when attempting to allocate maxmem values above what your CPU can theoretically address. • The error: • phys-bits too low (39): 61 • qemu-kvm: Address space limit 0x7fffffffff < 0x4bcbfffffff This is not just a warning, it's now a hard stop, unlike in AHV 2023.x which was more lenient or silently clamped memory ranges. What Are Your Options? If you want to stay on AHV 10.x: • Patch VMs to lower maxmem manually for each. • Limit to smaller memory footprints, ideally ≤ 16GB per VM. • Disable ballooning and dynamic memory reservations. But expect to continue hitting issues due to subtle QEMU/kvm flag incompatibilities. If you're testing/dev only: • Consider reverting to AHV 2023.x (AOS 6.6 or 6.7) where QEMU was more forgiving. • Or switch to Nutanix CE, which has relaxed CPU checks and allows more override flexibility. If you need long-term compatibility: • Move to Xeon-D or Xeon-E3 based NUCs, like the NUC Enthusiast series or Supermicro MicroCloud nodes (widely used in labs). You're correct that this isn't a BIOS issue, this is a design hardening in AHV 10.x. The InternalException masks what is really a low-level qemu-kvm memory init panic, and it's now unrecoverable on consumer CPUs. Your workaround on maxmem works but not sustainable unless you're using AHV in an unsupported/lab environment, which Nutanix won’t provide roadmap support for.

If I initiate an action/task in Prism Central, does it not show as a running task on PE? I see in the PE gui there are 3 running tasks, but when I connect via Powershell, the get-ntnxtask command shows nothing running

Anyone had any success with hosts using realtek network cards on CE? I keep having wierd issues with one host that uses realtek network card, but the other nodes are fine

Folks, I recently helped a customer deploy a bunch of Windows 11 24H2 persistent VDI machines on Nutanix. All was working ok but they have done a load of hardening (CIS, GPOs, Defender blah blah). Now when they add new machines, they register and blue screen shortly after. Looks to be caused by Hyper-V (not installed) trying to call VMX/Security features. They can workaround by disabling Hyper-V services but Id like to fully understand. Does anyone have a link to a blog/article that explains Win11 via Citrix on Nutanix that details key settings/Do's and don'ts around TMP, Secure boot, UEFI, cred/dev guard settings etc? cheers

Hello everyone.

https://download.intel.com/newsroom/2025/client-computing/Intel-Arc-Pro-B60-Data-Sheet.pdf ... "Ensure reliable, precise performance for common AI, design, engineering, architectural, and manufacturing software with a workstation-focused, validated, and robust graphics driver. Paired with trusted ISV (Independent Software Vendor) certified" Sounds VDI-ish, but last I checked it's Citrix-only for Intel on VDI?
