Copy or Storage Vmotion Very Slow

I have a 8 nodes nutanix with vSphere 7 deployed. I’ve created 2 new storage container with compression enabled and map to the nodes. I test to copy the file that i uploaded to the default container to the new storage container presented as NFS datastore...it was very slow. 5GB took 2hrs. Then i tried storage vmotion of a VM reside on the new datastore to another new datastore. A 10GB VM took 20 minutes. If storage vmotion from the default container to new datastore, it fails.

KVM Hypervisor - Management

Hello all, I'm wondering if there is anyone out there using Nutanix with KVM as a hypervisor, and if so, what kind of management do you use for daily VM related admin jobs? - virsh/virt-manager ? - RHEV/virto ? - OpenStack on top? - other "cloud solution"? - custom tools/scripts ? Please share :) I'm quite curious about official / eventual cross-vendor support and/or "show-stoppers" you might have experienced or enlightenments you might have had.. [i]P.S..: *psssst*...rumours have it, that Nutanix themselves are developing some "management tool" for KVM..anyone knows more?[/i]

jMeter On Nutanix

Hello friends, I am new here nice to meet you and I hope you can help me.I am working with two Scenarios in my client. One we have Nutanix on its Linux KVM-based hypervisor and the other we have common x86 servers running VMware.The objetive is compare both solutions and decide what's best. (we want Nutanix to the best of course!)The application running on both of them is a jBOSS system, on 3 virtual machines. (application, DB and one apache front end.)I created a recording test using jmeter, where the user makes a lot of steps in the web interface (for instance, search for a specific person, click on the menu, etc). The test runs fine on the x86 server and VMware, but on the Nutanix, after 150 users, I always get: Started: 0 Finished: 0. And also the CPU Usage is higher than the other scenario. Almost the double.I added more CPU and RAM to the virtual machine, but it didn't work. I am also running on non-GUI mode, removed the listeners, added more memory to the "MaxNewSize", but nothi

NUTANIX & NSX

Hi guys, I'm still digging to give corrects answer to my manager who is puting pros and cons for nutanix on the table. As I need to make a design without knowing exactly where he want to go, I'm making assomption on it. I understood that they wanted to put NSX on it VRA and vCloud SP. I've found a couple of recommandations / tips on NSX over NUTANIX but nothing that can be used on design part (more on implementation which is quite cool !) Do someone have integrated it on a 4.5 cluster ? do Nutanix plan to give us a technical note / any other cool stuff on NSX ? sheers,

Upgrade cluster from 5.20 to 6.5.2 using LCM

Greetings all,Testing out an upgrades I have faced some problems upgrading cluster from 5.20 straight to 6.5.2 AOS version using dark site web server. Even though the Upgrade Path shows that such upgrade is supported, and I was able to upgrade all the other components including the AOS itself using Prism LCM. The only problem is that after Performing Inventory and even after the upgrade complete it does not show AHV version changed or the upgrade available and the AHV version stays the same. I have tried to perform Direct Upload too and even though I could see the uploaded AHV version I still was unable to upgrade it. Upgrade to 6.5.1.8 version went successful, however. So  I had to try it with 6.5.2.5 and the result stays the same as with 6.5.2First I tried to upgrade fromAOS 5.20.1.1 AHV 20201105.2096 → AOS 6.5.2 AHV 20220304.342then after reimaging the cluster toAOS 5.20.2.1 AHV 20201105.2244 →  AOS 6.5.2 AHV 20220304.342.Both upgrades showed same results, then after reimaging the c

Display resolution in Windows Server 2016 (AHV-VM) stuck to 1280x1024

Ok, yesterday one of our many Nutanix clusters was upgraded to 5.15 LTS and I started to create a new Windows Server 2016 template using UEFI-configuration.   Now I am stuck at display resolution of 1280x1024 and change is not possible, because it is grayed out. Nutanix Guest Tools from 5.15 LTS and VirtIO 1.1.5 are installed.   Is this bug known and does there exist a work-around?   What about 5.16 STS? Is it fixed there?   Thanks for any reply.   Regards, Didi7

XenServer to Nutanix AHV VM Migration ERROR [Boot Device not found]

Hi,I am trying to move a Windows Server 2012 R2 VM from Xenserver to AHV. With reference to this article: AHV | Migrating a Windows VM from XenServer to AHV everything is working great except when I am at the last step. When I turn on the VM in AHV, I am getting a boot device not found error and windows will not boot up.Windows will start with a windows icon throws the error and restarts, then goes into disk repair, reboots and same error and goes into the troubleshooting menu and when I am restart the VM in AHV it again and always goes into the boot disk inaccessible error.I made sure all the Xen components are already uninstalled from the vm and Nutanix VirtIO drivers are also installed. Tried with loading the image as scsi and IDE, but still going into the same error. Also tried booting up in safe mode, tried disk repair, etc. but no luck.Please help if someone has a solution.PS: I am migrating Windows Server 2012 R2 from XenServer to Nutanix AHV.

PostgreSQL Performance

Hi Does anyone having experience or recommendation for tuning Postgresql Server Workload on Nutanix? We followed the Nutanix SQL Server Best Practices and Micheal Webster's Recommandations for vDisk and LVM layout at: [url=http://longwhiteclouds.com/2014/11/27/performance-testing-mysql-and-postgresql-with-hammerdb-and-pgbench/]http://longwhiteclouds.com/2014/11/27/performance-testing-mysql-and-postgresql-with-hammerdb-and-pgbench/[/url] Unfortunately, the Performance does not meet our expactation compared to our old PostgreSQL server running on a NetApp Filer.

IOPS&Latency issue

Hello mates, We have 2x NX3350 and Arista switch which handle roughly 100 VM. Workloads are: 20x VM with heavy disk workload which are used mainly for reporting and analysis. R/W ratio is roughly 50/50. They created 20K IOPS workload when they lived on SAN storage with RAID10 and tiny flash tier and average latency was always below 5 ms. 10x VM which are used for application virtualization 70x VM which are use for desktop virtualization. Now, when we migrated to Nutanix, we have only 4K cluster IOPS and 20 ms latency which does not seems to be very good for us. Trying to resolve the issue, we enabled inline compression and increased CVM memory up to 20GB. We also tried to change tier sequential write priority. Unfortunately, this does not help. ncc, cluster status and prism health claim that everything is ok. Before we migrated our environment, we've run diagnostic VM and the results was roughly 100K IOPS for read. Here is the current configuration of cluster:NOS Version: 4

Running OpenDNS VA in AHV

We attempted to migrate our ODNS as well as setup new VM's in AHV by extracting the vmdk's but each time we get the below screen on boot. Has anyone else successfully got the ODNS VA to run in AHV? I've tried editing the vm's xml file to change the video type and vram but no luck as of yet:[img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/df42756e-6765-4971-8d7f-63a99d3f8651.png[/img]

Real cost of AHV

Hi fellas,Does anyone have a clear answer of what is the real cost of AHV?  I’m told that AHV is free but is this referring to only Nutanix Community Edition? What about AOS? when purchasing a Nutanix node/block/cluster, these come pre-installed but the cluster essentially has no ‘smarts’ without the CVM which is AOS.Referencing this Licensing Quick Reference Guide, it looks like AHV is included with AOS but AOS’ licensing metric is charged per node.  Am I reading this correctly?Is it possible to run AHV without AOS? Thanks,JS

SQL Clusters on Nutanix and NOS 4.1.5

Hi All, Just wanted to let you know that using traditional SQL failover clusters and SQL FCI, or any MSCS / Microsoft failover cluster is available in tech preview as of NOS 4.1.5. This is because we have introduced SCSI 3 Persistent Reservations to the iSCSI stack. To implement a cluster you need to use the MS iSCSI Initator and the Nutanix Volume Groups contract and iSCSI target for in-Guest iSCSI access. This will become a full GA feature in an upcoming release of NOS. Please experiment with it and let us know your thoughts.

Server 2008 standard

Dear Community, I have an issue. I'm installing a Windows 2008 standard (not R2 nor SP1) on a AHV cluster and then I need the virtIO drivers. It works fine for the iSCSI passthrough driver and the baloon. But the Networking adapter is failed. It says drivers are not signed and cannot be verified, I bypass the warning and then it says there is an error, driver corrupt blablabla. I have tried the latest Nutanix virtIO without any luck - whatever OS version, they all failed. any magic idea ? Thanks ;)

VCPU(S) vs. Number Of Cores Per vCPU

Hello everybody, let's assume we have one Nutanix block with 3 nodes. In each node we only have 1 CPU socket with 10 Cores. A VM can only run on one node. So, in this case, wouldn't it make more sense to let a VM with 4 CPUs run on 1 VCPU and 4 Cores, instead of 4 VCPUs with 1 core, as each node has only 1 CPU socket? Or does Nutanix always recommend to use only 1 Core per VCPU not matter how much CPU sockets are available in a node? Best regards, Didi7

Problems with drivers on 2012R2 DataCentre edition

G'day one and all, We're a new nutanix site and have been migrating machines from our previous HyperVisor over to Acropolis/KVM. Our older servers have been no problems at all, 2003 and 2008 servers. however all our 2012R2 servers are having problems where the storage drivers are not being seen. To test I have tried a new install ont a VM from install DVD. Driver load screens comes up and I point it to the correct location on the nutanix VirtIO drivers ISO image. All drivers are seen, i.e. shows the correct drivers to load, but when selected and goes to load the drivers, and error stating "No new device drivers were found. Make sure installation media contains the correct drivers" The VM Disk is configured as scsi Regards, stephen...

Red Hat support

Hi I am an absolute noob so please be gentle to me. Can I know if Nutanix supports applications built that run on Red Hat Enterprise Linux? Basically, I have many applications that run on RHEL 7 that I am in the process of virtualizing using RHEV. So when I googled and saw this article below I was curious if Nutanix really supported RHEL and RHEV?
