Hi all,I am trying to install Nutanix on a former Dell VxRail node. The server is a Dell PowerEdge R640, and it has been re-branded back to a standard Dell R640 in iDRAC - the installation is only for Lab/testing, not for production.I have tried several installation combinations:Latest available AOS/AHV versions — although I understand these may not be supported on this older hardware Latest supported combination I could find for this platform: AOS 6.5.1.8 AHV 20220304.336 In all attempts, Foundation fails during the installation with the following error:CRITICAL svm_rescue: No suitable SVM boot disk foundAOS installation failed.

Hello everyone. We are deploying Nutanix for the first time using foundation v5.7 with 4node XC-660 servers and Dell S5224-ON top of rack switches. Launching foundation, we are getting repeatable Failure:"fatal: Running CVM Installer, Starting host installer"Phoenix is installed on all servers but that is as far as the install gets. Any ideas?We have a case open as well with Nutanix

Dear experts,I have successfully installed Nutanix Community Edition (CE) 2.1 on VMware Workstation, but I'm facing a networking issue.Environment Platform: VMware Workstation Nutanix Version: Community Edition 2.1 Allocated Resources: 65 GB RAM 8 vCPUs Installation completed successfully, and I can log in to Prism without any issues.ProblemAfter logging into Prism, I checked the Network Configuration, but the Virtual Switch list is empty. Because no virtual switch is available, I'm unable to create a VM since there is no network to attach.What I've CheckedInstallation completed without any reported errors. Prism is accessible through the management IP. The virtual switch is not created or displayed under the networking section.Has anyone experienced this issue with CE 2.1 running on VMware Workstation? Is there any additional configuration required after installation, or could this be related to the VMware virtual network adapter configuration?Any guidance or troubleshooting steps w

Running pc.7.5.1.6.We have a Guest Customization Profile (Guided Setup, Windows Sysprep) with Network Settings set to "Provide during deployment". When deploying a VM from a template using this profile, the Subnet Mask field in the Network Settings section pre-fills with 255.255.255.255.We looked through Prism Central for somewhere to change this default but couldn't find a setting for it.If left as-is (only filling in IP and Gateway, assuming Subnet Mask might not need touching), the VM actually comes up with a /32 subnet mask applied — not just placeholder text, it's a real configured value that gets used. This breaks connectivity since the host believes it's the only one on the subnet.Is this /32 pre-fill intentional, or should it default to something more sensible like /24 (or just be left blank/required)? Wondering if this is a known bug worth reporting via support, or if there's a reason for it we're missing.Anyone else hit this on 7.5.x?

Hi All, With the VM PowerShell module for intelligent operations, I have a few questions.For the path to the .PS1 file, can I use an SMB (Nutanix) share or does it have to be a local share  already mapped to the VM?The account in question would have access both to the VM and the SMB share

Hi all,As part of the planned replacement of our current Nutanix cluster later this year, we are reviewing the network infrastructure requirements for the new deployment.Since a large portion of our network is already built on Ubiquiti switching, I would like to evaluate whether the Ubiquiti Enterprise Campus Aggregation Switches would be a suitable platform for the new cluster.Based on the published specifications, these switches appear to meet the required connectivity and performance criteria. Before proceeding further, I would appreciate any feedback regarding their suitability for a Nutanix environment, particularly with respect to redundancy, high availability, east-west traffic handling.Has anyone deployed or validated these switches in a similar virtualization or hyperconverged infrastructure environment?Thanks in advance for your insights.Kind regards,Erik

I am getting ready to deploy a new Nutanix cluster next week and am preparing my Foundation VM.  I have imported the 7.5.1.6 AOS package which then states that the minimum AHV version is 11.0.1.2-33.  I’ve then downloaded this ISO from the link direct within Foundation and imported but I then get the message that this in an unsupported Hypervisor.  I’ve updated the whitelist but the hypervisor is still showing as not in the whitelist.  Am I ok to just install or do I need to check something else?

i  have a nutanix cluster  of node with (25gb ) uplink  and LACP is configured on it . i need to to expand cluster with nodes with ( 100GB ) uplink .i prepared the new node with below configuration:1-  re-imaged the new node with same version of AOS and AHV  as the existing cluster 2-  configured the  the new node with LACP my questions:1- is there any impact  to cluster that we mix speed of network as some node work with 25g and other with 100g ?2-  in expand cluster steps the is tab of network configuration is mandatory to set its configuratiion or can skip this configuration as i configured on new node , what will happen if i skip network configuration during expand 3- how long the expand will take to expand 4 node ?

Hi When entering a workload in Sizer, there is an option to select the existing CPU.For example, let’s assume that we are planning to deploy 100 VMs, each with 4 vCores and 8 GB of memory.  If I select “Yes, but I don’t know the current processor” and then choose Default, the estimated CPU utilization is approximately 75% when configured with a 3-node cluster, each node having 2 CPUs with 32 cores.However, if I edit the workload and select “Yes, but I don’t know the current processor”, the estimated CPU utilization increases to around 110%.In other words, I am not sure which criteria I should use when performing sizing.Why does the estimated utilization differ so significantly even though the workload itself is the same?Is there any detailed guidance available for this? It may be that I have not been able to find it, so I would appreciate your assistance.

Hi,I’ve got a question about where a VM on AHV get’s it’s time at boot-up from.Background:  I was reviewing the event logs on a couple of windows servers, and looking at the bootup process.  Event times, start at UTC and then a bit through the boot-up it jumps an hour to GMT (Presumably when windows time starts, and syncs with the domain)  I’d prefer this not to happen, and would like the BIOS/Boot time to be GMT if possible. Does the VM “BIOS”boot time come from the CVM which I’ve found the process to change the timezone for, or the Host which the recommended configuration is to leave at UTC?Thanks in advance G

We are trying to configure the CVM hardening recommendation to enable SNMPv3 only.  The Nutanix Bible lists the command as:ncli cluster edit-cvm-security-params enable-snmpv3-only=[true|false] #Default:falseHowever, the AOS 7.5 version of the Security hardening guide doesn’t list the command and execution fails with an invalid command. How can we enable SNMPv3 only or verify that SNMPv2c is disabled?
