AHV Virtualization

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?    

Is there an ACLI or NCLI command to keep a VM from using flash tier completely?

Create VM, Add windows server 2016 CD-Rom, 16 GB memory, 80 GB HDD Power on Launch console Console displays SeaBIOS (version 1.10.2-3.e17_4.1) Machine UUID And thats it no activity, no messages, nada

Let us consider a scenario where you are running specific workloads that require extensive video rendering and needs GPU-enhanced acceleration.   Nutanix provides a solution in which the hardware is configured with GPU cards that allow video rendering to be passed through to the User Virtual Machine.    Want to read about NVIDIA Grid vGPU on Nutanix?    The following guide will help in understanding the architecture and requirements of handling it.  

WE are planning to migrate 40 physical servers using Sureline. please if some one having some previous experiences .please comment.

Invested in HCI nutanix, but corporate executives is asking me to provide the following: cost per core cost per gb (Memory) cost per gb (storage) Pricing of Nutanix is always bundled (CPU memory and storage) not per line item How do i compute?

I’m in the process of migrating from VMWare to AHV.  I was curious if there are any licensing changes in regard to SQL.  Do I need to just make sure that I have enough core licensing to run the actual VM or do I have to buy core licenses for every core on my entire 4 node cluster?  I heard of something called infinity that I could use to keep my VM on just one node?  Thanks for your help!

Hi, Anyone know the highest supported ESXi version we can upgrade to on the Dell XC630-10? 

Attempting to add the Hyper-V feature to a fresh Server 2016 VM. I receive the message: "Hyper-V cannot be installed because virtualization support is not enabled in the BIOS" After picking through some very limited search results I attempted to modify the VM using "cpu_passthrough=true", however the error remains. Any advice to get this working? Thanks Andy

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 Reliability, Availability, Serviceability, and Scalability 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

Hi there,        I’m a network guy and this is my first time post here. Sorry if I broke any forum rule. We are having some issue with vServer host on Nutanix, and I would like to see if any experts here can tell the solution of the problem from nutanix stand-point. We have nutanix setup as LACP and connects to two nexus switches(5000) by using virtual port-channel. Sometimes mac address of vServer showed incomplete on arp table in one of the switches, not only one vServer. Then we finally realized that if we shutdown one port of the switch, which mac address incomplete in arp table, the vServer started to work immediately. After we executed no shut, the issue was back again. We checked the issue from switch stand-point, but couldn’t find any issue. Is anyone know the issue can be related to Nutanix? Thank you.

You have a new Nutanix solution configured using ESXi hypervisor and you’re facing issues with Networking like packet drops and NIC configuration. You want to check if you have quite a lot of RX/TX errors in the NIC or if your NIC is flapping. You might also want to check the VLAN and MTU configuration or how vmkernel port(vmkX)is configured. Troubleshooting is fun if you understand the architecture and know the commands. We have a knowledge base article to guide you regarding troubleshooting network issues on ESXi in a Nutanix environment and help to make the users a little more aware of the commands and the networking architecture. Go through the following KB to get a brief idea regarding network troubleshooting in ESXi.KB-1088 Go through the following vSphere Networking Guide to know more

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. @aluciani or I will post the link here as a reply once its posted.

Let’s say you have a new NX Hyper-converged architecture and want to use Hyper-V as a hypervisor, but now you are confused regarding the initial configuration and what all are required.Questions which are hovering your mind right now !!! What are the requirements to create a Nutanix cluster with Hyper-V? How can I image the nodes with Hyper-V and install AOS? How can I manage my Hyper-V host? How can I create a failover cluster and update Hyper-V settings? How can I create and manage VMs, especially HA VMs? Do we provide a documentation which can help you answer all these queries? Yes, absolutely Give this following documentation a read to easily get started with Hyper-V.

Hi   Would like to check if there is any tool which help in Migration from On premise physical workload directly to Nutanix Xi in AWS.   Let me know if it is technically feasible to do this.   On Premises server → Nutanix Xi in AWS (P-V Migration)

Can I get official documents / links from nutanix that PCI DSS is compliance with.

Let's say you're running a huge infrastructure of 10 pretty big SQL VMs and just shifted your infrastructure to Nutanix. You must be bewildered and confused regarding the best practices of SQL in Nutanix and how can you improve the performance. For most SQL server databases, there is nothing that needs to be done in order to successfully run on Nutanix.  SQL servers with small DBs are normal and okay but what about larger workloads?Do we have some best practices guide that can help us improve our performance?Yes, we have some general recommendation for running SQL workloads. Try giving the following Knowledgebase articles a read to understand the configuration and recommended settings to improve performance of SQL workloads.KB-3532

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.

Hi All,   One of my customer doing POC Nutanix right now. They create VM with application that use for Exam Online. So they set Public IP on that VM where their student can access for Exam from outside. Suddenly for 2 days the VM active, they found on their router that VM consume almost 500 Mbps internet bandwith usage. They already have that application on non-Nutanix server and not find any issue related.   Is there any application or service or something on Nutanix platform consume internet bandwith that we don’t know?

Hi !I want to make an image of a windows server on the ABS disk. How can I copy the file to images on CVM to start migrate the Fysical server to Virtual. WinSCP is so slow so it will take 6-7 hours. To write it to ABS iSCSI it is fast but only problem to copy it to AOS. File system is NTFS.thanks!-Kim W-

HiI am new in Nutanix , would you please explain for me the below stats , and what its performance in VMs performance , the cache stats screen i got it while the backup is running ?  

In our previous posts, we briefly explored some basics of vdisk management on AHV via Acropolis cli (acli). You can explore further namespaces in acli by logging on to any CVM and entering the acli shell.In some scenarios you may need to move disk from IDE to SCSI bus or vice versa. Sample scenarios including but not limited to:VM does not boot due to missing SCSI driver.  In such scenario disk can be converted to IDE to install missing driver and then move back to SCSI. Wrong disk type was used during VM creation. Disk index should be changed due to application requirements.From the AHV Best Practices Guide:Nutanix recommends using SCSI-based disks wherever possible for maximum performance. 

Is there an option to remove/detach a drive from a virtual machine? Cant seem to find it or look it up anywhere neither gui nor cli 😕

Understanding and knowing where a Virtual Machine stores its vDisk is important for Admins. In our previous post we explored a couple of ways, we can use to find where Virtual Machine vDisks are stored on a AHV / AOS Cluster. Quick Recap:VM Disks (vDisks) are stored in a Container on AOS Cluster Acropolis service is responsible for all VM Operations Acropolis service offers a powerful interface called acli acli offers TAB Completion acli can be executed from any CVM in the cluster, for VM info operationsIn this post we will first find the vDisk of a given virtual machine and then use WinSCP to connect to the cluster and download the vDisk.Su
