Network Segmentation and Port groups for BackPlane Network
Hi Our setup will look very similar to the attached diagram once it’s setup (taken from here - https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Security-Guide-v6_1:wc-network-segmentation-intro-wc-c.html). We won’t have the separate DVS for the VM’s though as these will be on the same DVS with everything else 😊 What I'm trying to understand is what the vmk2 kernel interface is used for and why this must be on its own port group and can’t use the same port used by the CVM. I’ve illustrated what I thought should be possible with the blue line. Within Prism where you change the setting for the Backplane network, you must select a port group for the CVM and for the host. However, when you try to select the same port group for both host and CVM it gives an error and won’t let you do it. Does anyone know why they need to be on separate port groups even though they will be on the same Backplane VLAN? I hope that made sense
Affinity rules light
Hello All, I am working with Affinity policies and I wonder if there is an Affinity “light”. What I mean by this is in Hyper-v clusters you have a “Preferred Server” this means that if the preferred server is available the vm will reside there if not it will move to stay running. Once the preferred server is back online then it will move back. Is this possible in AHV? Thanks,Scott

Dark site sever: uprading hypervisors & AOS
Dear Team,I had setup Dark Site web server (IIS) and uploaded unpacked LCM Dark Site Bundle and the firmware bundle (HPE). After performing LCM inventory LCM has been updated to the required version and “firmware” section is showing available new FW pack (SPP). Is any option to upload to the Dark Site server ESXi update file with metadata file or only one way to update it is to upload hypervisor metadata and binary file directly to to the Prism Elements?Software section is empty: Same question about AOS and File Server… Regards,Dominik
Host updates, firmware, bios, ESX, etc
Our current Nutanix infrastructure has been a bit neglected for a while, AOS, PC, NCC, etc have been kept up to date but not firmware\bios or hypervisor so I need to get these done.Current infrastructure is nothing massive, two clusters one 4 node one 3 running on NX-8035-G6 and NX-8035-G7, both are AOS 5.20.4. We have one PC running at the latest version and its sitting on a separate Management vSphere cluster along with vCenter. Hypervisor is currently ESXi 7.0 Update 2a 17867351 on all hosts, this is Standard Edition so NO DRS ☹ My plan is to upgrade the firmware and BIOS etc via the LCM on the smaller of the two clusters. I have freed up one host so there aren’t any VM’s on it apart from the CVM. I take it I can just run the LCM to do the firmware updates on that host and let it do its thing without having to do anything else, it’ll shut down the CVM maintenance mode the host and restart it?Once that is complete I want to upgrade ESX on that host. I have checked the compatibil
LCM failed performing action wait_for_services_startup
Hello, I recently tried to run an LCM upgrade of AHV Hypervisor el7.nutanix.202011005.30417 to version el7.nutanix.20220304.242 and ran into an issue where a failure occured during the upgrade and one of my clusters is now stuck on “Detaching node xxx.xxx.xxx.xxx from metadata ring” at a little bit of a loss as to where i can move forward from here. I am unable to launch the console for the CVM and cannot ping the CVM. I apologize for the formatting on this post. This is my first time posting and I am not too sure how to best format or attach screenshots.shown below.

Network Segmentation logically questions
Hello , I have two questions in “Network Segmentation logically”:I have 3 nodes (ESXi) with standard switch for every node , and i need to do logically network segregation to separate MGMT from CVM traffic The tasks which is need to be done in vCenter is 1- Create 2 port groups 1 for MGMT and the other for CVM traffic every one with different vlan Now ,1- I need to move CVM nic0 to MGMT port group and CVM nic2 to CVM traffic port group ? or Nutanix do this step ?2- From Nutanix configuration part , i need to add the vlan ID in “Backplane LAN Configuration Dialogue” or it is enough when i add the vlan ID in vCenter port groups?
Prism Central Tasks related to Reports
My Prism Central cluster (PC Scaleout) running version pc.2022.6.0.1 has ben generating Tasks related to Reports every few seconds - see screenshot below. This has been occurring for several days now and I don’t know if it’s normal or not - does anyone else experience this?
ESXi download versions for NX hardware
I’m looking to upgrade the hypervisor on my cluster of NX-8035-G6 hardware however the download site only lists ESXi version 7.0.0-ga (build 15843807) as the latest for this hardware line - which was released from VMware almost 2 years ago.Can I use this older .json file with newer versions of ESXi? For example version 7 Update 3?Or, since there appears to be support for these newer versions of ESXI for other vendors (like the Dell hardware line), can I use the .json files for the Dell hardware along with the new ESXi binary’s on my cluster of NX-8035-G6 nodes?

setting up a AHV cluster on 1G switches ( 3 node and 2 node )
Hello I am looking for guidance regarding setting up a 3-node and 2 node AHV cluster on 1G switches . Our workloads are low. The official response is to use a 10G switch fabric. If I opt for 2 node, can I connect the servers back to back for distributed storage ? Can data network go over 1G ? I plan to procure 2 servers with 2x 10G for distributed storage , 2x 1G NICs for data Thanks,Ajay

Adding new network adapters
Hi,we added additional networkcards into the servers, but when doing a ifconfig -a | less the additional cards/ports are not being displayed.Also the CVM starts and goes into a continous boot loop. the following is being displayed UNLOAD: attempting modprobe remove virtio-pciNow our question is why are the additional ports not being displayed? Are drivers needed in order for the CVM to boot correctly with the new card installed? Thanks
