what about memory management on ahv

Hi everyone, I'm struggling to find some documents about how ahv manages the virtual machine's ram. As far as I know, it doesn't share ram among vms....but, for example, what about overhead? Is it necessary to consider some overhead in addition to guest ram?Thank you all

Red Hat support

Hi I am an absolute noob so please be gentle to me. Can I know if Nutanix supports applications built that run on Red Hat Enterprise Linux? Basically, I have many applications that run on RHEL 7 that I am in the process of virtualizing using RHEV. So when I googled and saw this article below I was curious if Nutanix really supported RHEL and RHEV? [url=http://www.computerweekly.com/news/2240173672/Nutanix-supports-Red-Hat-KVM-in-upgraded-storage-stack-hardware-and-OS]http://www.computerweekly.com/news/2240173672/Nutanix-supports-Red-Hat-KVM-in-upgraded-storage-stack-hardware-and-OS[/url] Can someone confirm?

SAP Hana certified on Nutanix?

Hi, As per SAP Note 2428012 - SAP on Nutanix (Version 10 from Mar 15, 2017 in English), it states that " [b]HANA Support[/b] As of now, no Nutanix hardware is certified to run HANA workloads. However, if you wish to leverage a fully supported solution for HANA alongside Nutanix, only a Bridge to HANA solution is supported. For more information". Whats the latest new on this, is HANA supported now, if yes can you please let me know the SAP note or any source assosiated with it Regards Sreeram

Veeam One VM heartbeat alerts nightly in a chain by host

This is really weird, every night we are getting veeam one "Heartbeat is missing for VM" alerts from every guest in our protection domain, in a chain, by host. For instance, one host starts at 6:30pm and is all resolved by 8:50pn, then the next at 12am and resolved by 5am, then the last at 8am and resolved by 820am. We don't have backups going at 6pm (they start at 8) and the snapshots go all day, hourly, so it can't be those causing it. Seems like some sort of nightly maintenance on the hosts that would be causing the issue. Any idea where I could look to see those logs?

AHV VM CPU Usage consumes higher % than ESXi?

My customer reported that in their test, the CPU Usage of AHV VM always consumes 10% higher than ESXi so I am going to find out what is the most suitable reason behind this problem I have searched around and find out this blog below that having a paragraph pointing about hypervisor bottleneck: "The Nutanix Controller VM (CVM) runs on top of multiple hypervisors and delivers excellent performance, but there is always room for improvement. With our extensive experience with in-kernel and virtual machine based storage solutions, we quickly learned that the [b]biggest bottleneck is the hypervisor itself[/b]."

On the other hand, I have tested by myself on the scenario in which I have built up 2 VMs with the same configuration on 2 clusters having same Nutanix model and run the CPU tes

Migrate VMs with boot firmware set to UEFI from VMware ESXi 5.5 to AVH

I have a large number of VMs created with the boot firmware set to EFI. As I understand it, AHV cannot convert "out of the box" The options I have been told include the following:- [list] [*]Use VMware Convertor to perform a virtual to virtual VM conversion to change the boot firmware back to BIOS [*]Use an import tool to bring in the VMDK files over and run a CLI command to accept the UEFI setup[/list] Does this sound right? Is there an easier way? Can new VMs under AHV be created with UEFI ?

Replace HDD/SSD with different capacity

Hi, I would like to ask if Nutanix support replace SSD/HDD with different capacity. The reason I ask is that I want to keep the certain Hot Data ratio when data growth but without a growth on compute capacity. My concern is that if I just add the NX-6035C could allow me to growth my data, but the SSD may not enough for maintain the ratio of required Hot Data. Thanks.

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

HDDs in Hybrid Cluster: No Usage

Hi all, I have a case open for this with Nutanix Support, however, while I'm waiting... I'm wondering if anyone can explain why in a block that contains 12HDDs and 6SSDs (3-node block), only shows disk statistics for the SSDs and no values for the HDDs in the list (all metrics are 0).

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!

Slow Windows to Windows File Transfer

Hello, We have just migrated our entire infrastructure to Nutanix. We are in the process of moving an old file server to a new windows vm. We are running AHV as the hypervisor and are on 10GB ethernet. I am experiencing slow network transfers between these 2 VM's on the same Nutanix Cluster. So bad that the IOPS dont regiser above 300 in Prism. Any thoughts?

Incompatibility with Server 2016/Win10 and 2012r2 Hyper-V Cluster (AOS: v4.7.1)

AOS: v4.7.1 Server Platform: Multiple Hyper-V (2012 r2) clusters It appears that if you whitelist an IP that belongs to either a Server 2016 or a Windows 10 machine, that machine still can not access the SMB share being published by our Nutanix (v4.7.1) clusters. We found this out after upgrading our SCVMM server to Server 2016. At this point, the VMM server can 'see' the shares but can not calculate share size (reports 0GB) and therefore can't manage the share(s). Since then we've tested with multiple other 2016 and Windows 10 machines - all with the same result: added to the whitelist but can't browse the share, even from Windows Explorer. We are looking for confirmation that this is a known issue. If so, can you confirm if it's resolved by an upgrade to v5.0.2?

CVM Uses Dynamic Memory - Why?

Our CVMs are configured with 32GB of dynamic memory. Start, minimum and max are all set to 32GB. I'm curious to know why Dynamic Memory is enabled on these VMs? Since the CVM's OS isn't fully Hyper-V integrated, we don't see memory demand from the hypervisor (this is the only benefit I see from leaving dynamic memory enabled on a VM with all values set the same). As an explicit downside, since we're using Dynamic Memory on these VMs, we lose the vNUMA featureset (not that a 32GB VM is [b][i]likely[/i] [/b]to benefit from it). Thanks!
