AHV Virtualization

slow performance with Citrix MCS

Hi, we have a new Nutanix Cluster with three nodes. Now we will move our citrix farm from VMware to Nutanix.But on Nutanix the VMs much slower as on VMware. We use publish desktops with Citrix MCS an Fslogix.Login with VMware takes 15 seconds with Nutanix more that 50 seconds.The Nutanix Hardware much better then on Vmware.So we don‘t understand why it is so much slower.Also we use the Best Practice Guide from Nutanix for Citrix MCS.so have anybody an idea, why Citrix is slower on Nutanix and what we can do to speed up the system?

Packer Windows 2022 Boot Loop

We are new to Nutanix coming over from vSphere and are experiencing the same issues that is discussed but not resolved on this thread:https://next.nutanix.com/ahv-virtualization-27/packer-press-any-key-to-boot-from-cd-dvd-issue-43213We are using Packer to build a Window 2022 image. We have customised the ISO to remove the "Press any key to boot..." prompt. However, we are now in a situation where Packer/AHV doesn't allow us to specify a boot order so the CD is constantly booting, installing and rebooting.We can continue the Packer build if we manually dismount the CD, however, we want to be in a position where this is a hands off build and orchestrated by a pipeline like our vSphere builds are.Has anyone managed to get around this?

Issues creating 3 node cluster on bare metal

Hi All, I am trying to set up a 3 node cluster in Nutanix CE 2.1 but I don’t seem to be able to get past the creation of the auth certificates, my set up is as below: Dell PowerEdge R7515 2U Rackmount Server1 x AMD EPYC 7H12 64Core 2.6GHz CPU512GB (8x64GB PC4-3200AA-R) DDR4 RAM6 x 1.6TB SSD PCIe NVMe Gen 4 2.5" Dell Enterprise Hot-Swap SSD - used for DataPERC S150 Software Controller for NVMe Drivesx24 way Backplane for up to 24 x 2.5" PCIe NVMe Hot Swap DrivesDell BOSS Controller Card w/ 2 x 240GB M.2 SATA SSD - used for AHVBroadcom 5720 1Gb Dual Port Onboard LOM (2x1GB RJ45 Ports)Broadcom 57414 Dual Port Mezz LOM (2x10/25GB SFP28 Ports)1x 960GB PCIe NVMe Gen 4 2.5” - used for CVM these are connected to a Dell SF-S5148-ON 25GB switch which is then uplinked to a Sonicwall TZ470 firewall. the issue I seem to be seeing is that when creating the cluster, the CVM is unable to connect to the control master and then is unable to copy the certificate files via SCP, I have checked communicatio

How to stop and start cluster with script

We should type ‘I Agree’ when shutting down a cluster, so if is it possible to shutdown a cluster with script, or any method to bypass the manual confirmation?

Cost Governance

Consumption billing and reports

Hey everyone,I’m wondering if there is a built-in tool in Nutanix for on-premises environment that allows tracking of resource consumption — something that can act like a virtual currency or internal billing system based on usage (e.g., vCPU, memory, storage). Ideally, we’re looking for a way to generate reports that show per-project or per-VM consumption over time. I’ve thought of Cost Governance, but I think it’s only for cloud setups and I’m not aware of all its capabilities.Does Nutanix offer anything natively for this, or is this something that would require integration with an external tool?Thanks in advance!

Why CVM can not use all LACP bandwidth

We have eight XC nodes installed, each one connected to two 100Gbps switches ( 200Gbps btw two switches) by using two 100Gbps MLNX CX-6 network adapters. AHV and switches configured with LACP (Active-Active). After installation, we ran bandwidth with iperf:AHV to AHV could reach to 188Gbps ( 1 port with 20 threads) CVM to CVM was very close to 90Gbps (The total BW always was about 88Gbps, even we used multiple ports with multiple threads)So CVM can only use the bandwidth of one port of lacp for traffic?

How to add 2 more tape drives to a tape library in Veeam

I currently have a Quantum Scalar i3 tape library with 4 drives. I need to add 2 more drives to the library in Veeam. We bought a new SAS card, and have not yet installed it into the tape server. When I do, and connect the 2 new drives to it, I am unclear as to what I will need to do in Veeam to get it to recognize that there are now 2 more drives in the library, so I can add them to the correct media pool. Will it automatically see them?
