Migrating from Hyper-V to AHV

Does anyone know of any official documentation on the best way to perform a migration from Hyper-V 2016 on Nutanix to a new AHV cluster (not an in place migration)? Or any good guides on doing this? It is going from Hyper-V 2016 to AHV but 2012 would be helpful. I have found a few articles but they are either quite old or not very well written. https://vmwaremine.com/2016/04/11/migrate-windows-2012r2-from-hyper-v-to-nutanix-ahv/ https://vmwaremine.com/2016/06/06/migrate-hyper-v-generation-2-vm-to-nutanix-ahv/ http://vcdx56.com/2018/06/migrate-hyper-v-2012r2-vms-to-nutanix-ahv/ Thanks

Storage Utilization

Hello, I have turned on Windows Dedup for some of my file servers that reside on AHV, however the storage reduction is not reflected on Prism. Any thoughts as to why? I wish I could run the Capacity Dedup from AHV however the last time that I turned it on I received the following alert: Do not replicate protection domain XXXXXXX comprising entities from the storage container that have deduplication enabled to a single node remote site XXXXXXX. (XXX denote omitted field)

Space reclaimation for LINUX servers - RHEL 6.7 * VMWare 6.5

Hi All, Hope you are doing well. I have question regarding the storage usage and space reclaimation in VMWare 6.5 with Nutanix clusters. This question is more into VMware instead of Nutanix, thought of checking here. Just to give a overview we have Nutanix nodes and we have got VMWare 6.x installed on the nodes, a single storage pool and multiple containers. I got a RHEL VM migrated from the old environment and it got 4 disks (10GB, 20 GB, 500GB & 5 GB), all the 4 disks are in the same DS and thin provisioned. No deduplication & compression enabled on those. Now when I access the VMware web console and look for the vmdk files by browsing the files in the DS, I can see a different capacity from the actual usage compared at the server level. When I see the same VM via PRISM and I cannot see the 4 disks assigned to it. It shows only 1 disk with some 160 MB used out of 20 GB and none other than that. Could you please help me to understand why its not showing the disks in the P

Self Service Restore portal hangs

When I load the SSR portal through the desktop shortcut, or by browsing to locahost:5000 within a second or two the browser chokes and becomes unresponsive. I thought it may be related to the background animation, does anyone experience this also? Is there a way to disable the animation in the SSR portal page? Mant thanks, Daniel

Deploying Prometheus on Nutanix Karbon

This is the first of a three-part blog post on deploying monitoring addons with Nutanix Karbon. Nutanix Karbon is a curated turnkey offering that provides simplified provisioning and operations of Kubernetes clusters. Kubernetes is an open-source container orchestration system for deploying and managing container-based applications. Karbon was released in Tech-Preview after the launch of AOS 5.9 and Prism Central 5.9 in October 2018. We’ve received several queries from our customers, partners and peers alike who value the simplicity that we bring to the table for Kubernetes, but they find it hard to understand how the cluster is behaving and what is going on under the covers. Enter Prometheus (also known as Prom or P8s). Prometheus is an open-source monitoring tool that was built by a team at SoundCloud and it was inspired by Google’s Borgmon, it was designed from day one for the Kubernetes model of assigning and managing units of work. Prometheus has an expression bro

How to patch the recent Kubernetes vulnerability (CVE-2018-1002105) in Nutanix Karbon

Note: Nutanix Karbon is on Technical Preview so it should not be used on production. The steps on this guide may impact the existing running containers. This post covers how to patch the recent Kubernetes vulnerability (https://github.com/kubernetes/kubernetes/issues/71411). The version used as an example in this post is Kubernetes version 1.10.3, this is the only version tested but it should work on the same way for any of the other Kubernetes versions available in Karbon. Note: the SSH password is the known standard for Nutanix CVM 1. Gather the IP address for your Kubernetes nodes: code:kubectl get nodes -o yaml | grep address Output: code: addresses: - address: 10.10.56.174 - address: security-e8316c-k8s-master-0 addresses: - address: 10.10.56.150 - address: security-e8316c-k8s-worker-0 2. Connect to the master node and run the commands (change the IP address with yours): code:ssh root@10.10.56.174 code:sed -i 's/hyperkube:v1.10.3/hyperkub

When doing VM Migration from XenCenter to AHV, the VM gives a boot disk error at the startup in AHV after migration

PROBLEM: When doing VM Migration from XenCenter to AHV, the VM gives a boot disk error at the startup in AHV after migration. DESCRIPTION: VM to Migrate: Windows Server 2012 R2 XenCenter Version: XenCenter version 7.1 64-bit Nutanix HyperVisor: AHV I am trying to do VM migration from XenCenter to Nutanix AHV. I am referring this article (https://portal.nutanix.com/#/page/kbs/details?targetId=kA00e000000kAKJCA2) which seems to be the exact case what I am trying to do here. Every step is going smooth, but I am facing error only when the VM is migrated and when I start the VM it will always go into disk check and boot device not found error. See image: This is happening in both of the following case when I am creating a VM in AHV and mounting the disk image of the VM to be migrated: 1) When the DISKs are mounted as SCSI a. Now, when I am mounting the disks as SCSI which is the normal approach, the VM startup goes into the same error and VM will reboot and goe

XenServer to Nutanix AHV VM Migration ERROR [Boot Device not found]

Hi,I am trying to move a Windows Server 2012 R2 VM from Xenserver to AHV. With reference to this article: AHV | Migrating a Windows VM from XenServer to AHV everything is working great except when I am at the last step. When I turn on the VM in AHV, I am getting a boot device not found error and windows will not boot up.Windows will start with a windows icon throws the error and restarts, then goes into disk repair, reboots and same error and goes into the troubleshooting menu and when I am restart the VM in AHV it again and always goes into the boot disk inaccessible error.I made sure all the Xen components are already uninstalled from the vm and Nutanix VirtIO drivers are also installed. Tried with loading the image as scsi and IDE, but still going into the same error. Also tried booting up in safe mode, tried disk repair, etc. but no luck.Please help if someone has a solution.PS: I am migrating Windows Server 2012 R2 from XenServer to Nutanix AHV.

Remote site replication tuning

What options are available within nutanix to speed up replication to a remote site? The best i am able to get on a single stream is about 20MBps (160mbps) with an aggregate speed of about 60MBps (480mbps) spread out over several streams. However, we have a 10gbps link between sites, so i expected to get better throughput.

CSI Driver for Kubernetes

We have a new blog post that recently went live: Nutanix Releases New Kubernetes CSI–Based Driver CSI is an open and independent interface specification that describes or specifies how third-party storage providers can provide storage operations for Container orchestration systems. CSI makes installing new volume plugins as easy as deploying a pod, and enables third-party storage providers to develop their plugins without needing to add code to the core Kubernetes code base. The CSI Driver for Kubernetes leverages Nutanix Volumes (formerly known as ABS) to provide scalable and persistent storage for stateful applications. It was authored by a great team of folks Subodh Mathur (Engineering), Denis Guyadeen (PM), Dwayne Lessner (TME) and Christophe Jauffret (Architect) Continue the conversation from the article on this thread and let us know what you think!

Application Consistent snapshot on Nutanix Acropolis

Hi, Our customer would like to utilize the snapshot feature on Nutanix AHV as backup solution. They would like to know if they could create Application Consistent snapshot. I did some research. 1. In the Web Console Guide which mentioned about Application-Consistent Snapshots "This option is available for ESXi only; it is not supported for Hyper-V or AHV. However, athird-party product could be used to invoke VSS when the hypervisor is Hyper-V or AHV." 2. QEMU should have guest agent and which the VirtIO Driver should have included. So, my question is. Can Nutanix AHV support Application Consistent snapshot. Thabnks
