License-Free Virtualization for Your Enterprise

Hi I'm looking to created clustered files servers using Windows Server Failover Clustering - VMs will be in-guest, i'm using AHV. My understanding that presenting the Nutanix storage via iSCSI to WSFC servers is supported however i'm confused about how to setup the networking and the Nutanix ABS documentation doesn't make this clear. I'm used to creating a separate storage network / VLAN for all storage traffic however the iSCSI target IP address is recommended to be on the same network as the CVMs / all of the Nutanix infrastructure. So the question is do i create a separate network for storage and have it route to the iSCSI target IP address, or have the iSCSI initiators on the same network as the iSCSI target / data services IP? It wouldn't seem logical to mix the CVM traffic with storage traffic, however also not great to have to route storage traffic. Thanks Adam
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?

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]
Ubuntu installation on VM
Hi, I'm currently installing ubuntu on a VM. I notice the installation process is extremely slow. The downloading of files is going fast, but the actual installing isn't. Is this common when installing ubuntu on a nutanix VM? I tried different version, but they are all very slow. Thanks!
Migrating from Hyper-V to AHV
Does anyone know of any official documentation on the best way to perform a migration from Hyper-V 2016 on Nutanix to a new AHV cluster (not an in place migration)? Or any good guides on doing this? It is going from Hyper-V 2016 to AHV but 2012 would be helpful. I have found a few articles but they are either quite old or not very well written.

Determining appropriate methodology for cpu over subscription
We are new to Nutanix. We are migrating from ESXi to AHV. We currently have some level of CPU oversubscription in place on ESXi. We anticipate the need to oversubscribe CPU on some clusters and I am looking for ways to do this safely. I’ve looked in the Best practices guide but there was very little there. Any help would be appreciated.
dedicated CPU allocation
Hi, I'm a little bit new a Nutanix, however since last summer I can handle it very well Now I got a question wich I want to share here. I have to prepare a windows server. The requirments of the software wich will be hosted on this server preverene dedicated CPU and memory. So is this in the nutanix (AHV) installation posible to create a VM with his own dedicated CPU's (6cores) and memory? Regards Peter
Disk layout for Vmware SQL 2016 Guest Cluster
Hello all I'm trying to establish the optimal disk layout for a VMware MS SQL 2016 2 node guest failover cluster that will have a single SQL instance hosting multiple small to medium sized databases. Unfortunately we don't really have the funds for licensing to do the recommended approach of creating lot of small VMs to host these databases, so we need to consolidate where possible. I've been reading though the Nutanix SQL 2016 best practice guide and it's raised a few questions. I've decided to allocate multiple vdisks specifically for database files, so I'd have a few database files to each vdisk instead of one vdisk with all the database files on it. I'm assuming this approach might be better due to each vdisk having a 6GB Oplog allocation and so more vdisks would prevent a single oplog from quickly over filling? Is there any there real a benefit here to having more vdisks to spread the databases across or does this only really come into play when you split indi
Microsoft Exchange Server
Is anyone running Microsoft Exchange on their Nutanix cluster? If so, approximately how many mailbox databases (EDBs) are you running and what is the approximate size of each? Also, overall feedback/thoughts of the performance of your Exchange environment on the Nutanix cluster?
Elasticsearch on Nutanix
Ray Hassan from our solution engineering team has blogged about Elasticsearch on his site cannybag.com (don't ask :-) Here are some relevant blogs worth sharing: * http://cannybag.com/2015/10/elk-on-nutanix-elasticsearch/ * http://cannybag.com/2018/08/elasticsearch-sizing-on-nutanix/ Elasticsearch is also available as a pre-seeded app blueprint through Calm -- https://portal.nutanix.com/#/page/docs/details?targetId=Nutanix-Calm-Admin-Operations-Guide-v57:nuc-launching-elastic-search-app-blueprint-t.html Gabe Contreras, consulting architect in our services team is also writing up a blog about Elasticsearch on Nutanix that will be published soon.

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

what about memory management on ahv
Hi everyone, I'm struggling to find some documents about how ahv manages the virtual machine's ram. As far as I know, it doesn't share ram among vms....but, for example, what about overhead? Is it necessary to consider some overhead in addition to guest ram?Thank you all
2TB vmdk to AHV Migration
Hi, I have a standalone ESX 5.1 server with a VM with multiple 2TB (screenshot from WinScp attached below) vmdk volumes. VM is Windows 2008 R2. My Nutanix cluster is running 5.01, NCC 18.104.22.168, AHV 20160925.30 - Starter Edition I am planning to use a Windows 2012 R2 server with WinSCP to get the vmdk files onto the Nutanix cluster container (I have multiple containers) and then use the Image service (via Chrome browser) to upload/convert via UNC to the container. Here are my questions: [list=1] [*]I'm wondering if there are any limitations on the Image Server when using the Chrome Browser [*]Any potential issues with these vmdk sizes? [*]What is the syntax for the URL to access the Storage Container so I can upload the vmdk without using the UNC? -Figure this one out. In Image Service use nfs://clusterip/Containername/name ofvmdk-flat.vmdk [*]Since I need to upload multiple vmdk files that quite large, can/should I open multiple browsers to get simultaneous uploads happeni
Install NGT on VM template before Sysprep?
Is it ok to install Nutanix Guest Tools in a guest vm template before the template is Sysprepped? I need to deploy a bunch of Server 2008 r2 VMs that will need NGT. I'm aware that it's easy to automate NGT install AFTER vm deployment and I do that for most cases; however on Server 2008 r2 builds there's a techinical limitation that prevents this from working. So I'm wondering if there is anything in NGT that will break if the vm is Sysprepped afterward.
Migrate Data to Hyper-V cluster from another Hyper-V Cluster
What is the best approach to migrate data to a nutanix hyper-v failover cluster from a normal hyper-v failover cluster. I used export from the old host (Whitelisted in PRISM) and it succeeds fine but as the data is exported to the cluster FQDN, how do I know which node to use to import the files to make best use of data locality? is there a way to have the VM exported to a specific node?
Create Test Environment Alongside Production Environment
Hello Everyone! I am using AHV and would like to create a duplicate of my production environment alongside the actual production environment. The point is that we have some highly specialised network software that needs to be tested as though in the actual environment before we actually deploy it there. This software is frequently updated and occasionally an update creates havoc, requiring lots of downtime and restoration of significant portions of the network. So what i am looking for is to have a protected space in AHV that thinks and behaves identically to our production environment (but with no actual interaction with the real network or the internet ... just via AHV consoles.) Thank you in advance for any help you can offer!
