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!

VM creation automation

Hello All,I am new to Nutanix and AHV; however, I have a large amount of experience with Hyper-v and SCVMM. One of the things I am trying to do is automate the creation of a vm’s. My end goal is to take an “image” base drive I have uploaded to images containing an install of my windows OS.Deploy a new vm with that image, have a static IP assigned to the new vm automatically from a pool of IP’s, join my domain, and run a few powershell scripts in the VM. I would have done this all with an IP pool and a template in SCVMM and as much as I have read about templates in AHV I am not seeing anything like it. Am I missing something here?Do we have a resource on how to configure something like this?

ESXi 6.7u3 Patch - 1-click upgrade - Not compatible with current VIBs

I ugraded my ESXi hosts using 1-click upgrade to VMware-VMvisor-Installer-6.7.0.update03-15160138.x86_64-DellEMC_Customized-A04 with no issues. Trying to apply patch ESXi670-202004002.zip using 1-click upgrade and get the following error: Upgrade bundle is not compatible with current VIBs installed in hypervisor. [DependencyError] VIB QLC_bootbank_qedi_2.10.19.0-1OEM.670.0.0.8169922 requires qedentv_ver = X.11.15.0, but the requirement cannot be satisfied within the ImageProfile. I am able to successfully patch using esxcli and update manager.  I updated the image profile to DellEMC-ESXi-6.7U3-15160138-A04 on the hosts thinking that may resolve the issue but this did not work. Anyone have any suggestions to get 1-click upgrade to function with 6.7u3?

Use Nutanix Storage for a VMware external Cluster

We have a dozen or so VMs/appliances that do not support AHV and thus cannot be migrated over to our new AHV cluster that runs 95% of our servers. We would like to expose a container/Volume Group from Nutanix to the VMware hosts as NFS datastores to build these VMs/Appliances on. Our goal is to then replicate that Container/Volume Group to our DR Nutanix cluster and then connect our DR VMware cluster for the same VMs/Appliances to then use as well incase of failover. We have gotten conflicting information from all parties and wanted to know if anyone was already doing this and what your results are? These VMs/Appliances would have fairly high IO.

Does Nutanix Support SQL Cluster on ESXI5.5?

Hi All , As you know that to build a SQL cluster on vmware vsphere 5.5 I need to create RDM disk for both cluster's nodes with physical compitilty , and this will eliminate the vsphere from running vmotion (need to shutdown the host to migrate )since it is not supported. My question is : does nutanix support create a SQL cluster ? and how they will replace the RDM (the physical LUN)? And for licensing :Does nutanix base license support building critical application clusters for free? Regards,

DataCenter Refresh and the Nutanix Sizer for the Dell Product Line

The customer I currently support has a pair of Nutanix clusters running on the Dell PowerEdge XC630-10 harward platform. They have really enjoyed the performance and overall gain (simplicity of the design, reduction in administration/alerts, etc.) since moving to the Nutanix platform. The topic of a server refresh has arisen, and we're beginning to collect all the different metrics we will need to analyze to support this effort. After that's done, though, the planning and designing will begin. In the past, I've used the Nutanix Sizer. That since seems to be locked away behind a Nutanix/Partner Login page now? Does this still exist? Is there one that supports the Dell hardware platform line? Any other workload sizing resources for the theoretical migration planning would be much appreciated. Thanks, in advance!

CVM Resources Allocation

Hey Everyone. So, I am relatively new to the whole Nutanix game. Im curious what everyone is suggestion is for CVM allocation. We had nutanix do our original provisioning, but the provisions the installer set it up with seem a bit excessive. 10 Cores and 32gb ram per CVM, Any thoughts?[img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/2333i06E549D1B99C0D7A.png[/img]

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 3.0.0.2, 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

OvS Bonding

I am trying to implement SLB, or LACP, rather than A-B. To do this seems to require using either the manage_ovs show_bridges or list port {br0 | bond0} command. Other then the Command_Ref-AOS and AHV_Admin-Guid, where can more information be found ? I am getting a `ERROR kvm.py:488 failed to execute ....` error.

Cluster name must be in FQDN format

While attempting to upgrade from v4.7.1 to v5.x.x, the pre-upgrade fails with the following error: "Cluster name must be in FQDN format." Is there a way to upgrade the name from "CLUSTER" to "CLUSTER.domain.com" without downtime? Or, alternatively, is there a way to perform the upgrade without making this change/ingoring this message? Thanks all!

Server 2012r2 CHKDSK /SDCLEANUP crashes VM Everytime

We have a fresh Windows Server 2012R2 VM that we ran CHKDSK /SDcleanup on. After running for a period of time, the server VM turns off with no errors logged other than the fact that it was an unexpected shutdown. At first we thought something was corrupt, and since it wasn't in production yet we decided to just recreate the VM from scratch. Immediately after creating the new VM, we ran the same command and got the same results. It crashed while running on the C: drive running on boot up as well as on the 4tb data drive with zero data on it yet. So far we have been able to duplicate it everytime. We have a Xen Server with a Server 2012R2 VM on it and there is no issue running this command. Any ideas? Driver issue? Thanks Steve

AD DC on Nutanix Hyper-V

Hi I found the KB below stating you can't virtualize domain controllers on Nutanix Hyper-V. [url=https://portal.nutanix.com/#/page/kbs/details?targetId=kA032000000TTGWCA4]https://portal.nutanix.com/#/page/kbs/details?targetId=kA032000000TTGWCA4[/url] Quote: "Why? Because Hyper-V wants to contact the AD server before it can power up any VM on Nutanix storage, and the AD server would not be available because the VM cannot be booted." I am of the understanding that this might have been a thing in up until 2008 R2, but this should not be a problem when running Hyper-V on 2012 R2. Anyone that could shed some light on the matter? Would like to call the support line, but that is not an option right now since it has nothing to do with our own nutanix nodes. EDIT: Solved. Found out it is due to the SMB3 share of the nutanix cluster, which requires authentication from the domain.

MS SQL Clusters - Multiple SCSI Controllers

Hi All-I am in the process of creating some MSCS SQL Clusters on Server 2012R2 . In the applicable documentation in regards to using iSCSI-based VGs with Nutanix. Also read Mike Websters information about hot expaning the disks associated with those VGs in an upcoming software release, really nice! My question is about how I break the I/O over the multiple VMWare P/V SCSI controllers currently. If I followed the instructions in [url=https://portal.nutanix.com/#/page/solutions/details?targetId=BP-2049_Acropolis_Block_Services:BP-2049_Acropolis_Block_Services]https://portal.nutanix.com/#/page/solutions/details?targetId=BP-2049_Acropolis_Block_Services:BP-2049_Acropolis_Block_Services[/url] Wouldn't all the I/O go over the default and only SCSI controller for that VM? I am trying to distribute the I/O for logs, tempDB, etc over multiple SCSI controllers. It was worked well in our environment in which we leverage RDMs and would like to try to repeat this on the Nutanix side. Can
