AHV Virtualization

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? 

Hi All, I am trying to migrate one Windows 10 PC to Nutanix Acropolis. I tried to run a full backup with Veeam endpoint and tried the baremetal recovery in to Nutanix and that did not work. I tried this method for almost all of our servers (but they are already on nutanix) to restore into our test environment (running Nutanix CE) with out any issues. But this time I am doing it with Physical device to virtual and did not work. So is there any other method to do this. I see a lot of topics here mentioned vCenter converter but I never used it. Is there any particular steps I need to be careful about when using that tool.  Thank you,

Hello Folks, I see usually after satadom replacement of Hyper-V reinstallation we get errors in Live migration related to processor specific features. You can looks at the KB-6617 “Live Migration of VMs fails on Windows Server 2012 R2 or 2016 with processor compatibility error” We have couple of more KBs and Documents on Hyper-V live migrations you can check based on your error KB-3639 Shared Nothing Live Migration in Hyper-V Might Fail if it Takes More Than 10 hours to Complete KB-2247 Hyper-V: Live Migration, Configuration and best practices.

Hi everybody we are just in the beginning of the process of migrating our environment from VMWare to AHV. One of the scenarios that we need to consider for one of our application sets involves cloning an entire drive from a build server to a reporting server. Essentially right now I have a server that takes data and compiles it into a finished product on an intermittent basis.  When the server completes it’s build it calls another script that clones the drive to a reporting server.  Our reporting server has duplicate drives 1 online and 1 offline, the script overwrites the offline drive, then gets the drives to swap online state so that our clients are now reporting on the newly refreshed data. I am looking to replicate this concept and am hoping for a few pointers. In our existing environment I am making use of some of the storage commands for the disk clone.  I am hoping to understand how to replicate the disk clone from an AHV hosted Windows server. Would anybody have any sugge

There was a thread back in 2016 regarding getting VM activity events logged in Prism (PE or PC).  Events such as powering on and off a VM should be displayed in PE or PC so we can try to track down when a reboot may have occurred easily.  This has been a core VMware vCenter function for ages, but is glaringly absent in Prism for AHV. My company is in the middle of the AHV conversion right now, and my teammates are asking me how to find out about these events.  I don’t really like the idea of giving untrained folks access to the “nutanix” account on the CVM to look at acropolis.log.   In the 2016 thread, someone said enhancements are coming to Prism.  Are they still coming?

How To enable nested virtualization on AHV?

When creating a vm there is a scripting section that has the option to select a file from an ADSF Path.  How can I put files to an ADSF location?

Hello,  If you use balance-slb, how does one figure out which physical is being used by one VM ? For instance, with ESXi I’d run esxtop, and I can see which physical nic is being “mapped” to my virtual nic. Is it possible with AHV? If yes how ?  I think it is important when you troubleshoot.

Hi teams,   i have question about migration process in nutanix and esx, can i joining nutanix node in existing cluster on existing vcenter, processor in my existing node and my new nutanix node is same, and evc is enable, so can i joining nutanix and general server in same cluster?

You might have noticed a 100% CVM memory usage in the Prism Element or high CVM memory usage alarms in vCenter. In vSphere 6.5 and later, this issue is seen with virtual machines configured with PCI pass-through devices. Symptoms: In the vSphere Web Client: CVMs trigger the Virtual machine memory usage alarm. The VM's Memory Usage/Active performance metric is continually reported as 100%. In Prism Web Console: CVM Memory Usage % is permanently shown as 100%   There is nothing to worry about as this is just a cosmetic issue and has no effect on the CVM  performance. The NCC health check report will not include any errors or warnings regarding memory usage. Similarly, o alert will be generated in the Prism Element.   To take a detailed look at why ESXi displays CVM memory usage  as 100% and the solution for the above, take a look at CVM Memory is 100% in Prism and Web Client with ESXi 6.5 or later

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.

When is the next LTS version of the AOS due to release?

Hi, I have a customer who is having a cluster of 11 Hyper-V 2016 compute nodes and 2 AHV storage nodes. During a NCC health check, there is an error mentioning that the 2 AHV nodes are not syncing with any NTP server. The current NTP time sync setup is something like this.   Nutanix cluster (Hyper-V and AHV) → DC → NTP source   First question, how should we begin troubleshooting the issue? There is no remote access for our support to perform a webex session troubleshooting due to security.   Second question, customer is changing the NTP source. This new NTP source is 1-2 mins behind. Any impact if customer proceeds to update on the DC? Does the cluster auto sync up    Third question, at what time intervals does the nutanix cluster probe or sync up with NTP time?   Regards, Leonard Thng

Hi all I´m attempting to create one disk image from http server (I know that NFS is preferred) but i got errors from PE, acli and REST API. AHV, CVM, PE, PC and the web server are one the same network (then I can exclude routing issues)  and on the web server (Centos 7.7, apache httpd-2.4.6-90) firewall and selinux are disabled and the url is called using IP to avoid dns issues. The content is available via wget but the image creation command ends with error 503 (Service Unavailable) while on the web server with log at debug level nothing is written on error and access log.   I have tested also to stop httpd and use python -m SimpleHTTPServer 80 but doesn´t work (I got one excepction that I cannot fully read and I don´t know where is logged)   What´s wrong? I´m missing something? Someone have a suggestion?   Here some operation samples:   Download test using wget to check http service ~~~ nutanix@cmv:~/tmp$ wget http://192.168.158.40/images/gm-back-test-001-scsi1.qcow2 --2020-03-17 16:

Hi Team,   We are running few file servers (windows 2016 machines) which are running on Nutanix + VMware 6.5. For e.g. i have a 5TB VMDK attached to the VM which is holding up a lot of files (being a file server). Now when we check the size of this disk in VMware, we this as around 4TB consumed (similar figures in Prism as well). However within Windows, the actual space consumed is only 1 TB.  The question is - how do we reclaim this space to match up the numbers seen by OS with what VMware believes the used space is. (i have seen some posts where users have mentioned using sdelete etc. but it isn’t really a scalable solution)  Thoughts ?  Thanks. Ravi  

Hi, my name is Rossana, I am new to the community and I have a question, I would like to know if someone can help me to know what kind of requirements NUTANIX must have to install SAP Business One, with 25 users and a HANA Database engine of 64GB with an average of 20,000 monthly transactions. Thank you very much

Are you going to have a planned power outage or relocation procedure that needs to shut down your Hyper-V cluster safely?   Maybe you have experienced this situation: We have a scheduled power outage at this location for Dec 31th. We are going to need to power everything down prior to the outage. What is the best way to safely power down the Hyper-V cluster? With Hyper-V Clusters it is important to consider the following procedure before shut down all the user VMs in the failover cluster : Make sure that you have at least one domain controller running outside of the Nutanix cluster. Otherwise, you will not be able to start VMs after powering on the cluster. Make sure that the Hyper-V hosts are configured to use this external DC/DNS server. Disable all Metro Availability-enabled Protection Domains, and make sure no on-going replication is happening. Consult the article Disabling Metro Availability for more details. To check the complete procedure and the details follow through to th

I'm trying to upgrade ESXi 6.0 to 6.7U2 but when try to do it from Prism im getting errors on DRS not enabled. Now we don't have DRS license, our cluster is ESXi 6.0 Standard License, is there any way to do the upgrade without the needs of DRS ?I read few documents that even if i try to use vCenter Update manager update will fail becasue DRS is not enabled. Any workaround solution ?

In the last few weeks we have been experiencing complete host CPU usage at 100% on all of our host(6 of them). We were never this high. When the system is at this level no one can do much on the ystem for a few minutes. The biggest change we did was add Bitdefender Gravity Zone to our system. We have about 650 VMs on the system. Memory usage hovers between 50-60% on all the hosts. We are running ESXI hypervisor with VMware Horizon to run our VDI system. Anyone have an insight into this situation? Is there any tweaking I need to do? What could be causing this?

Hi all, I´m attempting to download one image from a cluster on port 2222 as described on many documents (i.e. AHV | How to access VM disk files on Nutanix container or Copy files to/from a containter ) and I have a strange issue: using Filezilla or Winscp it works fine, using Centos 7.7 Linux scp doesn´t work. A syntax as “scp -P 2222 admin@VCM-IP:/default-container-171248/.acropolis/vmdisk/image-or-disk-uuid” accept the password and then terminate with error “exec request failed on channel 0” On the linux side firewall & selinux have been disabled a scp to other systems works fine. Any suggestion?
