How It works

Do you want to import Third Party Appliances on AHV and wondering about following questions?Is my Third-Party Appliance compatible with AHV? What is supported and un-supported? How will I migrate my Appliance to AHV?We have multiple options that can be used to deploy Third Party Appliances on AHV. Third-party application vendors provide different applications or appliances that are certified to run on AHV.Here is the full current list of such applications: Compatibility MatrixNote: Software vendors can utilize this link to request an official software validation on AHVFor more details, refer to KB 9849

Hello!We have 5 node RF3 cluster. I tried shutting down 2 of 5 node at a time. Cluster stays online, but rebuild never happens. Is it normal? Should 5 node RF3 cluster rebuild after loosing 2 nodes? Can it survive loosing 1 more node after already loosing 2 (only 2 of 5 stays online)? 

Hi All, Wondering if anyone has scripted the addition and configuration of nic’s for VM’s that have failed over in a PD? Noticed a few posts from a few years ago but seeing if approach has changed at all. My approach (no script yet): Check which PD’s have become active at remote site to get list of vm’s grab mac and ip info from a mainted csv (plan to use dhcp reservations on dhcp server) Add nic’s with info grabbed from csv Perform some DNS updates Power on Interested to know what others are doing and any feedback on my approach would be appreciated. Thanks! -PeteP

By default, the Prism Central login page includes background animation, and users are logged out automatically after being idle for 15 minutes. You can disable the background animation, change the session timeout for users, and override the session timeout completely.Some points to note:1. This setting is not persistent. In other words, if the Prism service restarts, this setting is lost and must be disabled again.2. Disabling or enabling this setting in Prism Web Console does not propagate to Prism Central or vice versa. The setting must be disabled in Prism Web Console and Prism Central UI separately.3. The timeout interval for an administrator cannot be set for longer than 1 hour. For more information on the details and steps, click here. 

Hello - We created a custom DISK Image and need to automate the upload to Nutanix. Is there a way for us to programatically upload an image using powershell?

While maintaining your Nutanix environment, there is a need to apply patches to keep everything running smoothly. Some of these patches require reboot of the CVM or Hosts to take effect.For example, rebooting all hosts in a cluster means manually putting the host in maintenance mode, evacuating the VMs, turning off the CVM, rebooting the host, waiting for the CVM and host to boot up, and confirming the cluster data resiliency is OK before proceeding to the next host. As you can see, there is a lot of manual work involved.However, there is a simpler solution: leveraging the rolling reboot script. The script utilizes our shutdown token feature to ensure that the node is up and running before proceeding to the next node. If you are using AHV, the script will be available in Prism. For ESXi hypervisors and for more robust options (even for AHV), there is a command line option found in KB 4723More information about the prerequisites (please read this before using) and execution can be found

Hi,I am trying to monitor the CPU ready time (hypervisor.cpu_ready_time_ppm) for the VMs on AHV but the metrics available via the API does not provide this particular metric.The host metrics available via the API areHost_hypervisor_avg_io_latency_usecsHost_hypervisor_avg_read_io_latency_usecsHost_hypervisor_avg_write_io_latency_usecsHost_hypervisor_cpu_usage_ppmHost_hypervisor_io_bandwidth_kbpsHost_hypervisor_memory_usage_ppmHost_hypervisor_num_ioHost_hypervisor_num_iopsHost_hypervisor_num_read_ioHost_hypervisor_num_read_iopsHost_hypervisor_num_received_bytesHost_hypervisor_num_transmitted_bytesHost_hypervisor_num_write_ioHost_hypervisor_num_write_iopsHost_hypervisor_read_io_bandwidth_kbpsHost_hypervisor_timespan_usecsHost_hypervisor_total_io_size_kbytesHost_hypervisor_total_io_time_usecsHost_hypervisor_total_read_io_size_kbytesHost_hypervisor_total_read_io_time_usecsHost_hypervisor_write_io_bandwidth_kbpsHow can I report on this metric?Thanks. 

 key-based SSH access to a cluster is supported. Adding a key through the Prism web console provides key-based access to the cluster, Controller VM, and hypervisor host. Each node employs a public/private key pair, and the cluster is made secure by distributing and using these keys. Users can create a key pair (or multiple key pairs) and add the public keys to enable key-based SSH access. However, when site security requirements do not allow such access, you can remove all public keys to prevent SSH access. To control key-based SSH access to the cluster, do the following: Steps:Click the gear icon in the main menu and then select Cluster Lockdown in the Settings page.The Cluster Lockdown dialog box appears. Enabled public keys (if any) are listed in this window. To disable (or enable) remote login access, uncheck (check) theEnable Remote Login with Password box. Remote login access is enabled by default. To add a new public key, click the New Public Key button and then do the followin

With the introduction of download pages on the Nutanix Support Portal, The download bundle links now come with an expiry time set to them.wget command-line utility to download the bundles directly on to your CVM however chops down the signature files on the download links, this is due to the Download links being too long for wget command line utility.There is method to wget a release bundle from the Nutanix Support Portal directly to a CVM. In order to wget a release bundle on to a CVM/Host, run the below command on the CVM where you wish to download the bundlenutanix@cvm$ wget “url” -O <filename>Note: Filename can be obtained from the Download link as shown in the highlighted text above. wget "http://download.nutanix.com/downloads/ncc/v3.10.0.1/nutanix-ncc-el7.3-release-ncc-3.10.0.1-x86_64-latest-installer.sh?Expires=1595478032&Signature=Rb3R02qRIZZWVaHwAr1N7aj7AXQ3NOYPySn1AyF4H77HzhdxXEcVp7YBEGbd7h-oA~CVgkJWwla-iqGWSw4CAJmrugIhM0iXAUCIW-n0aNAvMbEOxxquRRQcMCwpNuHtSchwkOqZ~wR

The Nutanix platform and all products leverage the Security Configuration Management Automation (SCMA) framework to ensure that services are constantly inspected for variance to the security policy. Nutanix has implemented security configuration management automation (SCMA) to check multiple security entities for both Nutanix storage and AHV.  It continuously assesses and heals Nutanix clusters to ensure that it meets or exceeds all regulatory requirements. In this process over 1,700 security entities are analyzed and self-corrected across storage and hypervisor (AHV only) layers. Nutanix automatically reports log inconsistencies and reverts them to the baseline.With SCMA, you can schedule the Security Technical Implementation Guides (STIG) to run hourly, daily, weekly, or monthly. STIG has the lowest system priority within the virtual storage controller, ensuring that security checks do not interfere with platform performance.To learn more about this feature, click here.

 Networking on a Hyper-V host is very similar to networking on an AHV host and an ESXi host.  Naming of objects is again different, but functionality is the same: Just like with AHV and ESXi, the hypervisor has a connection to both the InternalSwitch and the ExternalSwitch.  The name of the hypervisor on a Hyper-V host is confusingly also Hyper-V, and this hypervisor attaches to virtual switches by way of a vEthernet port.  All virtual network adapters are where the VLANs are defined, and also where the network names are defined.  Hyper-V doesn't have port groups, it has network names which don't work at all the same way that they do in AHV. Verification Commands from Powershell Get-netadaptervmq Get-netadaptervmqQueue   Please refer to this link for detail explanation of Networking in hyper-vhttps://portal.nutanix.com/page/documents/kbs/details?targetId=kA0600000008fOSCAY

So I recently asked this question…  https://next.nutanix.com/api-31/playbook-rest-api-post-teams-37756?postid=51764#post51764 I saw support for slack but no teams… I got to looking and sure enough API’s are available to call from within playbooks yipee!    Youll need to create an incoming web-hook in teams (google this if you dont have it setup).  open up a team channel, click connectors  select configuregive it a name, upload an image and hit createOnce you do that you now have a url which an be used to post messages to via script or whatever your flavor is.    In nutanix heres what i set   Prism Central    set a custom alert policy to 5-10% cpu so it would trigger a lot and selected my test vm   Result: niceeeeeObviously this is my very fist time attempting this and I literally just figured it out but in the near future Id like to see if I can call the alert parameters, include useful information automatically e.g only alert on critical, and include the alert info.

We are looking to combine our two nutanix blocks together.we currently have the NX-3360-G6 and the NX-1365-G6. if this possible to achieve, do we have have to double up on the redundant connections per node? this would mean it would be occupying 12 sfp+ connections all together. can anybody shed some light or experience on this?

Dear Team, I purchased 3 node IBM Power node running with AOS.Once i am trying to create ticket with Nutanix they said raise ticket with IBM vendor but i couldn’t understand if the Issue with AHV then why i should log ticket with IBM?IBM vendor Only responsible for hardware issue.Please suggest anyone how to register the ticket IN kuwait region if customer having IBM power Node with nutanix native AHV.

Continuing on the previous post on all things snapshot. A few more questions today:What happens when I delete a snapshot? Do I loose data? R. You loose a recovery point but not the data, regardless, if it is the first snapshot, the snapshot in the middle or the last one in the snapshot tree. Let’s take a look at a few examples: A. You take a snapshot, create a file within the guest OS, take another snapshot and remove that file. Then you delete that snapshot. Whether that snapshot was in the middle of the chain or the first/last one, that file is no longer recoverable. B. You take a snapshot, create a file A, take another snapshot, create file B. You remove the first snapshot. File A is till there. You can no longer recover to the point in time where file had not existed yet however.If I recover a VM from a snapshot what happens if I then delete the snapshot? R. The VM continues to operate just like it used to while the snapshot was still in place. The only difference is that once the

​​​​​​Cluster lockdown is the ability to disable password based CVM access and/or only allow key based access to users.Nutanix recommends that access including SSH directly to CVM and hypervisor should be restricted to as few entities as possible. In high security settings, Cluster lockdown can be very appropriate and should be implemented Cluster Lockdown does not effect any cluster communication between its components. Cluster will function as normal.It ultimately boils down to requirements. You can choose the level of security and give access to only a select few when the cluster is in lockdown mode. Below are few helpful links that can help you secure your Nutanix Clusters : KB 1895 - How to create a password-less SSH login to your Nutanix clusterKey Based SSH access to CVMSecurity Guide

 Ever wondered what are some of the main services/components that make up Nutanix?The following is a simplified view of the main Nutanix cluster components.All components run on multiple nodes in the cluster and depend on connectivity between their peers that also run the same component. Cluster components ZeusKey Role: Access interface for Zookeeper·  A key element of a distributed system, zeus is a method for all nodes to store and update the cluster's configuration. This zeus configuration includes details about the physical components in the cluster, such as hosts and disks, and logical components, like storage containers. The state of these components, including their IP addresses, capacities, and data replication rules, are also stored in the cluster configuration.·  Zeus is the Nutanix library that all other components use to access the cluster configuration, which is currently implemented using Apache Zookeeper. MedusaKey role: Access interface for Cassandra·  Distributed sy

We notice that after deleting VMs or Files the free space on Nutanix cluster doesn’t  increase instantly and may only reflect after a few hours.  This behavior of free space being slowly presented back to the cluster is expected behavior for Nutanix. The reason for this is because of the service responsible for cleaning up space, Curator. Curator takes time to perform scans on the cluster and spreads the storage across the disks and carefully removes the correct files (egroups) while maintaining redundancy for any data you want to keep. It takes a few curator scans before all expected free space is available again. Each curator scan is scheduled to be performed once per hour. To remove more data, it will take longer time for curator to clean up data relative to the existing workload of the cluster. In case after 24 hours, the space is not reclaimed and does not appear as free space, contact Nutanix Support for assistance with diagnosing the cluster health.  Portal document explaining t

Hello Community,Just, I want to know how can I setup a Solaris 11.4 or Solaris 11.3 VM on Nutanix, any guide or walkthrough?. Please, let us know how can we have this OS running on AHV. We have AOS 5.15 LTS.
