Defragment Guest OS

I was wondering what best practice is for defragmenting guest OS on a Nutanix node.  I am running ESXi on the nodes.  I have looked all over but I cannot find anything that tells me definitively the best practice.

Problem exporting files from Nutanix NFS

I'm trying to move our vms from one cluster to another but the built in remote site don't work so now I'm trying to manually move the vmdisk files to the other cluster but the NFS connection stops working after a while. I have tried to mount the NFS share in a ESXi server but the transfer errors out after a while. Now I'm trying to use qemu-img to convert the vmdisk and move it, but it fails with : qemu-img convert nfs://127.0.0.1/default-container-49239103706845/.acropolis/vmdisk/81cd6231-e421-441c-850c-9124adf565d0 -O qcow2 ./dns-export.qcow2 & NFS Error: NFS: Read failed with NFS3ERR_JUKEBOX(-11) qemu-img: error while reading sector 4202495: Resource temporarily unavailable Is there any logs that will tell me what is happening with the NFS connection?

Veeam Backup on Hyper-V 2012 R2 VSS issue

Long shot i know, but i’m wondering if anyone every solved the issue of VSS backups failing after June 2022 Update on Hyper-V 2012 R2 hosts. Veeam has this KB Article that references a workaround/fix:  https://www.veeam.com/kb4333However, it’s not at all clear how i would make a domain account an administrator/backup operator on the File Server that hosts the SMB3.0 share (the cvm..)

OSD via SCCM problem AOS 5.10

Keep getting an error while trying to deploy Server 2016 on AHV using SCCM. Has anything changed recently? I used VirtIO v.1.1.4. Do you have to have NGT in sccm also?

VM memory dump creation procedure for Acropolis (VM)

HelloI am interested in the possibility to get a VM memory dump for further analysis (list of processes, sockets, other artifacts). How to do it if using the KVM hypervisor (Acropolis).I need to create a dump on a running VM for analysis. A detailed description of the procedure is required. If I understand correctly, all VMs in Nutanix are kept in the form of files, which files are VM dump files? Оr does Nutanix have a special procedure for creating and downloading a complete dummy file(s) of a virtual machine?OS doesn't matter, it can be anything.Please tell me the information to understand this issue.

Assistance installing community edition for testing

Hey Team,I need a little bit of assistance here. I am new to Nutanix and currently attempting to deploy the community edition for some testing. However, I’ve been following several different guides out there and not having much luck.Installing on VM using ESXi 7.0 (VM version 17). I created new VM w/ Centos 7 compatibility and loaded the ISO.ISO was downloaded from here:https://next.nutanix.com/discussion-forum-14/download-community-edition-38417And md5sum matches.The ISO loads and boots up. I then go through the CLI UI installation and get past to the last screen where it should start installing but then get an error that I need help troubleshooting:Last Screen:Then the Error right after the previous screenshot:Looking at the error, there is reference to minimum requirements but I’m pretty sure I meet them on this VM but if this is what it is, then I can look at a newer beefier server to test on:8CPUs24GB of MemorySata1 20GbsSata2 50GbsSate3 50Gbs​Anyone seen this error before?

Packer - Nutanix Builder

Hello,I'm working on building a Debian 12 image for Nutanix, but I found it difficult to start the automatic Debian installation process (DebianInstaller). Unlike other virtualizers that I have worked with so far, Nutanix does not have the "boot_command" parameter to start the self-installation process.Is there any documentation or tutorial on how to proceed in this case?Thanks for any guidance.

Credential Guard

Can Credential Guard be enabled via GPO for 2016 servers running in AHV? Or is this something that only applies to servers running on a HyperV host?

KVM VM on AHV?

Hi, AHV is based on KVM, but I can't find any documentation that states that you actuelly can run/move KVM VMs on AHV. Can anyone confirm this? We have a customer who wishes to move their KVM VMs to our AHV environment. :) So we want to confirm that it is possible. Best regards Peter

How to schedule a VM power state with AHV

I will looking to migrate from VMware to AHV in the next few weeks. As I understand it, it is not possible to schedule the state of a VM say for Shutdown or Power On, as you can do in VMware. Is there a workaround and is this on the roadmap?

2012 VMs intermittently locking up resolved

I've had an intermittant problem with some 2012 VMs I had migrated that have been locking up after a random time, usually going to 100% CPU and all IO stops. VM Console is unresponsive and network not reachable, reset is only solution to bring back online. It would then run again for a number of minutes, hours, even a day or more only to do same thing again at a random time through day or night, so was no logical patten to it. I endup tracking it down to a timezone config issue, when rebooting the VMs in question the timezone would set their clock to the hypervisior host time, which was in a different timezone (default TZ nodes were shipped with) to the the host VM TZ. I had a similar problem in the past, although not with the host lockups, where a number of hosts would lose time sync and be out by the TZ difference between host and VM on our Citrix XenServer Cluster hypervisor host. Because our VM are on an AD domain they will be out of NTP adjustment range becasue time differen

Network and storage segregation

Hi all, My present client is making me working on a design implying to deploy a XAAS plateform with a lot of security inside (NSX is on the cook list). In our team, i was declared as the nutanix man. My mission is to determine the best way to isolate storage from diffrent workload : [list] [*]we'll have an integration zone, a developpement and a production zone as PAAS. [*]Some node will executed heavy VDI (K2 graphic cards will achieve this), [*]Then we'll have a IAAS with vcloud SP for the sandbox zone).[/list]So we can imagine some sort of multicluster with 3 cluster dedicated to 3 zones : 3D VDI zone / SANDBOX IAAS zone / and PAAS zone. It implies at least 9 nodes which is a bit too much for starting plateform. [b]My question is[/b], can I make a 6 node cluster for nutanix / storage point, with 3 volumes pools on all 6 node ? and more than that what will it implies in terms of storage performance, data protection, data seggregation (security team will challenge me heavily on

Nested Shares on AFS

Hi, we have the need for nested shares on our fileserver. While this was easy on NetApp Filer it seems impossible with Nutanix AFS, or I am missing something. We are currently on latest GA release AFS 2.0.2. with AOS 5.0.2 on ESXi 6.0U2. Is this on the roadmap or even possible with AFS 2.1? Replacing Fileservers (Windows or NetApp, doesnt matter) could only be done with full feature set. best regards Steffen

Nested HyperV on AHV

Has anyone successfully been able to get HyperV(or ESXi) nested under AHV? I do see nested [b]KVM[/b] VM's are supported but no mention of anything else. Only reason for exploring this is to get Cisco Umbrella VA's working under AHV so i don't have to re-purpose an old server to run HyperV/ESXi.

Hyper-V - Persistent Reservations & Corrupt VHDs

[b]How do Persistent Reservations work with Hyper-V on Nutanix?[/b] [list] [*]I'm asking because with our other "Hyper-V with SMB Storage" clusters, you are not able to use Hyper-V manager on [b]HOST1[/b] to modify VHDs that belong to a VM running on [b]HOST2[/b], as you would expect - Error reads: "Access Denied".

ESXi5.5 Upgrade and patch installation - Supported-QA vertified

Hi all, We have a 3x node Dell XC630-10 Cluster running on AOS4.5.0.2 - Starter License. These nodes are running a Dell Customised 5.5U2 VMware image. I want to upgrade these nodes to a Dell 5.5U3-A04 image build 3248547. This will have to be done manually as we do not have DRS running (Standard VMware license). On top of the image I want to patch them to "Patch 8" level - release date - 04/AUG/2016 (Patch 9 available now). However reading the [url=http://www.nutanix.com/support/support-faqs/#hypervisor-support]Hypervisor FAQ[/url] it seems that major/minor vSphere releases are supported and QA certified within 90 days of GA. Therefore my question is: After applying the Dell 5.5U3 Custom image then, in theory, I can only apply Express Patch 10 build 3568722- 22/Feb/2016? Comments are much appreciated.
