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...

Windows Admin Center
Environment: Windows Server 2019 version 1809 (core and with graphical user interface). At the moment I am working for a customer to do migrations to Windows Server 2019. Since the migration of the virtual environment by the customer from VMWare VSphere 6.xxx to Nutanix AHV, version 20170830.412 I have the following problem. Before the installation I could work with the Window Admin Center on a Windows Server 2019 without any restrictions. After the installation the Windows Admin Center can be opened, but several error messages appear: Error messagesPerformance class not found:CPU performance class not found on this computer.Remote Exception: The property 'Product' cannot be found on this object. Verify that the property exists. Type: ErrorRetrieve user settings and extensions: RemoteException: The property 'Product' cannot be found on this object. Verify that the property exists. This means that no more data is displayed in the overview and the Tools bar of the Admin Center is on

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.
APC UPS - Graceful Shutdown for AHV
I am currently running VMware but will be soon switching to AHV. Will be purchasing a APC UPS with parchute software. Does anyone know if this is compatible for AHV? Does anyone out there with a UPS running AHV care to comment how they are managing the graceful shutdown of their Nodes and VMs in the event of power loss?
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.
SSH Public Key is removed from ESXi
Hi,we are running 20 Nutanix Nodes with AOS 5.0.1 and ESXi 6.0 as hypervisor. Normally we using passwordless login to the ESXi host using SSH Keys. So we copy our public key as usual to /etc/ssh/keys-%u/authorized_keys, but after a reboot of the ESXi Host our keys are removed.So I modified the sshd_config on the ESXi host to use multiple authorized_keys- AuthorizedKeysFile /etc/ssh/keys-%u/authorized_keys+ AuthorizedKeysFile /etc/ssh/keys-%u/authorized_keys /etc/ssh/keys-%u/authorized_keys2But even with this config, the authorized_keys2 is also deleted.Can anyone assist me to solve this issue in case of our internal security guidline to use passwordless login.Best regardsMarkus
Should I stop the cluster to set Erasure Coding?
Hi, I'll create new cluster for 3 nodes that maybe expand. If I add node to cluster, Should I stop it to set Erasure Coding ? Or Should I set Erasure Coding at create new cluster before running user VMs ? I'm concerned about some impacts user VMs running on new cluster for that setting.
What organizations lose when not chose Nutanix as the Hyper-Converged Infrastructure (HCI) Solution – Part 1
Technology landscape is changing rapidly, and IT teams in organizations should embrace the newer technology at the earliest as it would be refreshed in no time. Meanwhile, there are some technologies which are making their presence felt and getting enough attention that every other vendor is willing to launch or have a me-too product irrespective of its [b]Reliability, Availability, Serviceability,[/b] and[b] Scalability[/b] features. The technology is Hyper-Converged Infrastructure aka HCI. The organization coined and pioneered this is Nutanix Enterprise and a product initially good for running Virtual Desktop Infrastructure (VDI) Solutions has become de-facto standard for all kinds of virtualization workloads be it VDI, Remote Office Branch Office (ROBO), Business Critical Applications (BCA), or similar virtualized workloads. Nutanix is about to complete 10 Years in industry, lot of things have changed from its inception as a Hardware Appliance-based Solution to True Hybrid Cloud bas
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
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.
Single larger drive or several smaller drives attached to VM?
We are in the process of setting up a new fileserver using AHV and Windows 2019. Our current physical server has one larger 2TB drive letter for all file storage with 3-4 various shares. My question is would it make any difference to keep this same setup with AHV, 2TB drive attached to the VM for storage for files, or would it be better to have 2-3 smaller attached storage drives?
HyperV/Nutanix (SMB), VM import from Hyper-V manager
Hi, I'm trying to import a VM using hyper-V manager but it is always saying "can't access folder, you might have not permission to access this folder" and tried to check all VMs and the same issue shows up. Any idea why this error is there? I'm thinking about modifying the permissions on VM folder, can we? knowing that i'm trying to access the VM folder from container share path [example: \container_name.........] We are running hyperV2012R2 on nutanix 4.7.1 Thank you, Pierre
Progress Database optimization for Nutanix cluster - Monster VM on Acropolis
I have 3 x 3000 series node each with 256GBs of RAM, and 1 cluster. - 7.2TB Total SSD Flash (2.4TBx3 nodes)- 12TB Usable HDD (before de-duplication/compression)- 2.6GHz/20 Cores, 6 Physical CPUs: 60 Total cores- 768GB Total memory We are running pure Acropolis. The monster VM workload is a Progress database that is 7TB in size and has 200GB RAM allocated to it. We are setting this up as a PoC to migrate off a standalone ESXi host with a Violin all flash array. Previously, the VM on VMware was only pushing 12,000 IOPs. What should we be doing to optimize the performance for this VM? Multiple virtual scsi adapters? Also, is there a way to see if the working set is exceeding the node cache capability?
Deploy Prism central on Nutanix with Acropolis Hypervisor
Hi Community, I would like to deploy Prism central to manage 2 clusters. Until now, nothing complex. The issue is : Prism Central is provided as an OVA to be deployed with ESX but I'm using KVM/Acropolis. Is there a way to import it ? Can you please provide me with some guidance ? Thanks a lot.
