VMs won't power on - QEMU error

Hello, first time poster. I’ve created a one-node cluster on an intel NUC 10 (NUC10FNH) using latest phoenix image. install went fine after a couple of hardware bumps but node is up, CVM is running etc. The issue I’m having is I can’t power on any VMs I create. It only gives a generic “InternalException” error. In the uhura.out log, there are these entries “Error: HypervisorError: internal error: QEMU unexpectedly closed the monitor” and “qemu-kvm: Address space limit 0x7fffffffff < 0x4bcbfffffff phys-bits too low (39): 61”. Having a hard time trying to make sense of this. I’ve read other people running on the same hardware with no issues, maybe it’s the specific version of the CPU (it’s an i7-10710U). one-node cluster, 64GB RAM, one 500GB m.2 SSD and one 500GB SATA SSD. booting off a 64GB usb drive. Any info would be appreciated. Thank you.

Replacing (renewing) hosts for two node cluster

We have a two node cluster running hyper-V and hardware has come to EOL.We need to replace the nodes with new supported hardware and I cannot find any documentation for this, specially for a two nodes cluster. Is there any documentation available or can anyone provide the procedure? I know hardware replacement is supported for two nodes clusters, I just cannot find instructions for it. Thanks in advance

Packer Windows 2022 Boot Loop

We are new to Nutanix coming over from vSphere and are experiencing the same issues that is discussed but not resolved on this thread:https://next.nutanix.com/ahv-virtualization-27/packer-press-any-key-to-boot-from-cd-dvd-issue-43213We are using Packer to build a Window 2022 image. We have customised the ISO to remove the "Press any key to boot..." prompt. However, we are now in a situation where Packer/AHV doesn't allow us to specify a boot order so the CD is constantly booting, installing and rebooting.We can continue the Packer build if we manually dismount the CD, however, we want to be in a position where this is a hands off build and orchestrated by a pipeline like our vSphere builds are.Has anyone managed to get around this?

Disable proxy ARP within the Nutanix VLAN. What? How?

Hi,“Disable proxy ARP within the Nutanix VLAN before configuring network segmentation” is mentioned in two documents.Security GuidePhysical Networking Best PracticesCould someone clarify what this means exactly?What is “the Nutanix VLAN”? Is it the “CVM/HOST management VLAN or all VLANs? What is the command to disable proxy ARP? Should this be done at the Nutanix level or the physical switch level?I couldn't find answers in the documentation. Any help would be greatly appreciated!Thanks in advance!

Upgrading ESXi 703c to 703s from vCenter instead of Prism Elements?

Good day nutanix community We are to upgrade our cluster from ESXi 7.0.3c to 7.0 U3s to patch for the latest CVE vulnerabilities, BUT, in the Compatibility and Interoperability Matrix there is no information about this ESXi Version so, it´s is supported this ESXi? Current AOS version 5.20.4.6 LTS upgradable to 6.5.6.7 LTSModel NX-1065-G7Can I upgrade the ESXi hosts from the vCenter LCM without needing the ISO and JSON files for they hypervisor upgrade in Prism Elements? Is the model and AOS version there compatible with ESXi 7.0.3s event though the compatibility matrix doesn’t show it, and the latest JSON file I can get from Nutanix website is 7.0.3n?

Need Help NCP-MCI-6.10

Hey everyone, I’m currently preparing for the NCP-MCI-6.10 exam and struggling to find good practice tests. Most of the ones I found online are too basic — they just touch on general topics like “What does the Prism Central do?” without diving into the actual exam format or technical depth.Can anyone recommend realistic practice exams that closely match the certification style and help with actual understanding? Would really appreciate it — thanks in advance!

【Nutanix CE】GPUパススルーの構築について

現在、本番環境構築の検証としてNutanix CEを導入したホストマシンを1台構築しており、その上にWindowsの仮想マシンを2台作成しています。仮想マシンにGPUを利用する製品を導入し正常動作するか検証したいのですが、Nutanix CEではvGPU用のドライバは利用できないと判明いたしました。代替案として、GPUパススルーを利用して1台ずつ動作検証したいと考えているのですが、構築手順が分かっておりません。sshでCVMに接続し、acliコマンドを発行を試しているのですが「Unkown keyword argument」と表示されてしまいます。対応策についてご存じの方がいればご教示いただけないでしょうか。<コマンド># acli vm.update “VM名” pci_passthrough_devices=”PCI_ADDRESS”Unkown keyword argument：pci_passthrough_devices<環境>・ホストマシン 1台検証向けにNutanix CEを導入し、仮想マシンを作成AHV：バージョン 20230302.101026AOS：6.8.1・仮想マシン 2台Windows 11 Pro 24H2ArcGIS Pro 2.9

Windows 10 vTPM not recognized by intune

Hello,We're encountering an issue related to TPM on our AHV devices. While looking for solutions, I found a similar case, but the resolution there was related to the processor rather than TPM.We're trying to perform a feature upgrade from Windows 10 to Windows 11 through Intune, and this issue is blocking the process.Has anyone experienced this problem and found a solution?Thanks!
