CPU frequencies in AHV vs in VM

Hello, We have recently set up a new Nutanix infrastructure consisting of two clusters, each with three AHV nodes. The hardware comprises ThinkAgile HX650 V3 CN servers, equipped with Intel(R) Xeon(R) Silver 4416+ CPUs (2GHz, up to 3.9GHz). The BIOS of the AHVs is configured to Performance Schedutil. Our concern is that the VMs are operating at a CPU frequency of 2GHz. Monitoring shows that the CPU frequency never exceeds 2GHz, while the AHV CPUs average around 2.8GHz. Is this behavior a bug, or is it by design? Is there a way to change and increase the CPU frequencies used by the VMs? We are still learning about the Nutanix infrastructure and would appreciate your assistance. Thank you.

Can't enable NFS, even after updating to the newest version.

Hello! I’m unable to enable FNS on my test CE nutanix cluster, even after updating both Element and Central to the newest version using LCM. If anyone have any clue of what I’ve done wrong, it would be much appreciated.

How to view the history of vm migrations

Hi How can I view the history of vm migrations. We had business impakt on an application, that apparently is so sensitive that a migration between nodes in the same cluster caused a split brain situation according to the supplier. However I want to see if that particular vm was migrated in that timeframe the supplier indicated. Can someone provide me this troubleshoot procedure?

How to increase the sinze of Prism Central?

In this single-node hardware environment (24C/384GB/4x800GB) I have installed Nutanix CE 2.1 which work fine. I then wanted to test Prism Central and deployed it in size x-small which turned out to be too small (could not do all fun stuff). How do I increase it to size small instaead? I tried to just add the extra cpus and memory to match the size of small, but that was not enough, it still said that it was x-small. Then I tried to remove PC to create a new larger one, but it wasn’t as easy as I thought. The VM wasn’t possible to delete without deregister but the deregister was blocked but a objects-lite database which wasn’t possible to remove! It just referred to KB-17159 which literally only said “Contact Nutanix support”… But this is CE and I’m just a partner playing around without support… Any procedure for size upgrade of Prism Central? (I searched in the portal but failed)

Is Network Controller supported on Community Editon 2.1?

Hello, just finished installing a new CE 2.1 cluster to experiment a bit, and a new Prism Central. Trying to enable Network Controller, but it says my cluster is not supported. Is this not a feature supported by CE? Or would I have to use a different Prism Central version?

Community Edition, can't reach CVM's when trying to segment backplane LAN

Hi! I’m trying to segment, the backplane LAN on an already existing cluster, it passes the validation, but then I get this error when it gets to about 45% Anyone know what i’m doing wrong?I’m following this documentation Link My CVM’s use 10.10.10.11,21,31 And AHV use 10.10.10.10,20,30 Trying to get the backplane to use a 10.10.11.0/24 on a different physical switch. All ports are VLAN tagged with VLAN11 just like the This is the error I get When looking in the Foundation logs, they fail to ping eachother, but I don’t know what the issue there could be, they are using the correct IP’s and the interfaces are up on both sides.

VM resolution stuck at 1280x1024 after MOVE from ESXi to AHV

We are starting to migrate from ESXi to AHV, using the MOVE application. And as the title says, all the VMs are stuck on 1280x1024 resolution when they come up on AHV. I’ve tried the “Preferred Resolution” change mentioned here Display resolution in Windows Server 2016 (AHV-VM) stuck to 1280x1024 | Nutanix Community I change the Preferred resolution from “<Unset>” to “1920x1080”, but as soon as I exit and boot into Windows, it goes back to 1280x1024 and won’t change. Some posts mention not having Guest Tools installed before the MOVE, but that made no difference for us. I’m stuck at the same resolution, regardless of whether Guest Tools was installed prior to MOVE or not. Nor does the method of access - launch console or RDP, the VM resolution is hard coded to this annoyingly small (by 21st century standards) resolution. And all my VMs are UEFI, which is pretty much the default. And obviously that can’t be changed, without deleting the whole VM. Is there any workaround or resolution (s

Updating tools results in hanging at uefi upon reboot. Has to be power cycled to then boot to Windows Server

SCSI disk 100gb, 16gb mem, Server 2016 standard desktop experience, dual xeon icelake Likely other configurations, as this has happened with multiple VMs, still collecting data, but wanted to get something started in case others have experience with this. My first thought is obviously some uefi configuration with boot order or something, but doesn’t really make sense, since it only *seems to happen* right after tool updates. *updated as it’s not like we reboot often, maybe it will happen without updating as well.

Storage tiering for QLC SSDs

I am considering building a cluster that will use a mix of TLC and QLC NVMe SSDs. I assume that Nutanix will put all of these drives into the SSD-PCIe storage tier and every disk will be a member of the same tier. Since QLC SSDs have lower performance and lower write endurance than their TLC, MLC, and SLC counterparts, it would be advantageous to use storage tiering to encourage cold data to reside on the QLC media and hotter data to reside on the more performant drives. Is there a supported method for this in non-community edition clusters? It would be relatively straightforward to manually change the tier-name for the QLC drives to SSD-SATA, but is that a supported practice?
