Multi node failure after rebuilding task was finished

Hello. I have questions about node failure in AHV. (I assumed that all resources for rebuilding are enough.)3 Node cluster with RF=2 1 node was failed. And after that rebuild task was finished. In this situation, Does cluster status or data consistency fine if 1 more node failed ? (It is mean that only 1 node is available)    9 Node cluster with RF=2 1 node was failed. If rebuilding task finished ever node failure, Does cluster status or data consistency fine if multiple node failed ? ( I mean that - Node01 was failed. Rebuilding finished. - Node02 was failed. Rebuilding finished. → cluster status or data consistency fine ? ( two node failed. 7 node available) - Node03 was failed. Rebuilding finished →  cluster status or data consistency fine ? ( three node failed. 6 node available) - Node04 was failed. Rebuilding finished →  cluster status or data consistency fine ? ( four node failed. 5 node available) - Node05 was failed. Rebuilding finished →  cluster status or data consis

Installed Nutanix Community Edition but can't create a cluster

After successful install, I try to create a single-node cluster using the ‘cluster -s cvm_ip --redundancy_factor=1 create’ from the guide here: Community Edition CE 2.0 - Creating a Cluster (nutanix.com) I have an ssh session on my CVM and I am met with ‘warning mainthread genesis_utils.py 1580 failed to reach a node where genesis is up ensure genesis is running on all cvms’ . I then try ‘cluster start’ but it says ‘Cluster is currently unconfigured. Please create the cluster’. This has happened for me on different hardware as well. Any thoughts on this issue?

Expand Cluster with New Node

Dears, we are planning to expand a cluster consists of 3 Nodes, the new node supposed to come with DiscoveryOS the Existing AHV and CVM are using tagged VLAN, could you please advice if using expand option from the prism element will be able to discover the new node and re-image it ? should any preparation be done on the node before the expanding  AOS version is 6.5.4, foundation is 5.4, IPV6 is enabled on the switch. from Prism webUI guide i can see “If the Controller VMs in the cluster reside in a VLAN configured network, the discovery process still finds any factory-prepared nodes regardless of their current VLAN status (configured or not configured).” → in our case it’s coming with DiscoveryOS.

Deploy Windows VM through Ansible

Trying to deploy a VM through ansible playbook.  Deployment work fine. But I would like to configure IP address, netmask and gateway. Also I would like to add code for joining the vm to AD domain. Looked into guest_customization. But I am not finding any documentation on how to use guest_customization. There is some, but it only for Linux systems. Any tips/references will be appreciated. Thanks Yezdi

DMZ cinfiguratuin

Hi,I have configured a 3 node nutanix cluster with an active active lacp configuration. We have 2 more ports on the node which we wanted to use for dmz. However the prism element gui configuration fails continuously. I tried removing the 2 ports from the br0 bridge and add to br1 bridge. Doing so is only supported in one node, on the other nodes it is not reflected. Kindly suggest the right method or commands to configure since none of them seem to work. Also whether is there a separate vs switch configuration is needed for the scenario? Ps: I don't have flow or prism central. And since it is in deployment state, license activation is also not done

Would Nutanix consider selling their AHV as a standalone product?

Food for thought - If Nutanix wanted to grab more market share and with Broadcom taking over VMWARE, would VMWARE customers be interested in AHV as a hypervisor in a non hyperconverged environment?   I know it goes against the grain of what Nutanix wants to offer (Hyperconverged) but for some smaller customers with  only a few nodes it is a very productive solution with the big hit on disk in a 3 node cluster.

RDP Connections Freezing - Windows Server 2022

RDP to guest vm’s running Windows Server 2022 are freezing a few seconds after connecting. Running latest VirtIO drivers 1.1.7. After rebooting the guest, RDP seems to work ok for an hour or so before freezing again. Guest memory utilization 48%, CPU 3-5% so no issue there.
