Nutanix supports an Prism Central upgrade path from current version N to target N+2 in most cases.

Hi there We are running pc.2023.4.0.2 and because we would like to upgrade to AOS 6.8.1, we need to first upgrade the Prism Central to pc.2024.x. However, upgrading from pc.2023.4.0.2 to any pc.2024.x at the moment, it’s not supported. As of today, the latest PC Version is 2024.1.0.2. I do understand the upgrade N to N+2, but when it comes to PC, i don’t know what N+2 means relative to pc.2023.4.0.2.Considering that AOS 6.5 is going EOM in Oct 2024, we are a little afraid that we’ll not be able to upgrade our AOS’es 6.5.x to AOS 6.8 in time, because PC 2024.x is a prerequisite for AOS 6.8. What to expect here, and how to proceed? Best regards,Casian

Is there a webinar on VM creation with Rest API or Postman?

I'm looking for information about VM creation with REST API or Postman, and so far I can't find anything “good”, I find it strange because Nutanix always have very good information, but in this case I can't find much, neither videos, I know there is no Test Drive. But they should have some videos on this important topic.

No compatible versions for deployment - Prism Central

From prism Central Element, I am trying to deploy Prism Central. When I go for create new Prism central through Prism Central Element GUI, it did not list out available versions. Instead, it just shows “No compactible versions for Deployment”. Following is what I have. I am using nutanix hardware.Version 6.8.1 - COMMUNITY LicenseNCC Version: 5.0.1LCM Version: 3.0.1.1 Not sure, how I can deploy prism central If I do not have binary. If I uncheck the option “Only show compatible versions”, it lists out following public version.pc.2023.4.0.2pc.2022.6.0.10pc.2022.6.0.11pc.2022.6.0.12 In that case, I had deployed pc.2023.4.0.2 but i never able to get GUI. I suspect the compatibility issue.Any help would be appreciated.

Volume group with multiple Disk for Windows failover Cluster

Hi all,Today we have Set up a Windows file failover cluster.WE have configured a volume group with one vdisk for quorum and one volume group with two vdisks for data.Windows see the two disks in the second volume group seperately. WE have attached the volume groups directly to the Windows VM.Why is the volume group seen as seperate disks?Should it not be only one? Regards,Thomas

Initial Configuration: AHV passwords (root, admin, nutanix)

Hi all,I just setup a new AHV environment and was wondering if it still needed to change the passwords for the users:adminnutanix...on AHV!https://portal.nutanix.com/page/documents/details?targetId=AHV-Admin-Guide-v6_8:app-ahv-access-initial-config-t.htmlThe reason for asking is, that they do not seems to be the default passwords (tried to login with them  - did not work: nutanix/4u) - and also the standard alarm that informs that you need to change these disappeared just after I changed the root password!Has something changed in ver. 6.7 / 6.8 ?

Replication

Hello, I am seeking your assistance with enabling replication on my cluster, which consists of 5 servers and 60 VMs. I am undecided between Metro mode and Asynchronous mode on Prism Central. Given that I have two clusters using Metro-type replication, we encounter difficulties when Metro mode is activated, as clients experience significant slowdowns on their VMs. This is why I am considering enabling Asynchronous replication on Prism Central. My question is: if I activate Asynchronous replication on Prism Central while other clusters are using Metro mode, will this have any impact? Thank you for your help.

Migrating Data from Old VM to USB Drive

Hello,We have an old VM that is in our Nutanix cluster. It is running an old version of Windows server, and our Cyber department does not want it connected to the network. There has been a request to retrieve historic data from the server.  Is there a way to boot the server with the network disconnected and use a USB drive connected to the Nutanix host to export the data? If there is no way to do that what other possibilities will work? Can the virtual disk from the old server be mounted on a new network connected VM? Thanks

Eve-NG: Build Virtual Labs on Nutanix

Create your own virtual networking / security lab without having to purchase hardware.Eve-Ng is similar to another popular networking/security tool called GNS3.  I’ve run (GNS3 successfully on HyperV.)Both products are network emulation hypervisors that allow you to, say, load real IOS images from your environment to run them as virtual appliances.  You can emulate routers, switches, firewalls, WAPs, clients, web servers, etc.Then you can test IOS upgrades, routing changes, or whatever you want without having to risk messing with your live environment.  It’s also a great tool for education.The environment has a visual dashboard that allows you to see your network in a GUI, similar to Cisco Packet Tracer, GNS3, or MS Visio.Eve-ng is based on KVM and appears to be running very well nested inside AHV.https://www.eve-ng.net/You will need to prepare AHV to allow the VM to run as a nested hypervisor.The following commands will allow you to do that and so far that is all that was needed to ge
