AHV Virtualization

Hi guys, we're planning to move/migrate my MS SQL workload from physical standalone host to a new Nutanix cluster. We already engaged with local Nutanix representative for this. However, we encountered a few hurdles in terms of performance during and we can't be sure whether we have the right sizing for our performance requirement. Current Production Physical host:- Processor: Intel Xeon E5-2690v3 @ 2.6GHz (single socket, 12C 24T) RAM: 96GB (However only 64GB usable for the MS SQL 2008R2 DB) Disks: Database MDF resides in a SSD RAID 5 diskgroup. (6 disks), OS and LDF etc resides in other disk groups, SAS disks 10K, 15K RAID 10, RAID 1 etc. Test Unit ( 3 nodes):- Processor: Intel Xeon E5-2650 v4 @ 2.2 GHz (dual socket, 24C 48T) per node RAM: 512GB per node Disks: 6 x 1.6TB Intel S3610 SATA (All Flash) Hypervisor: AHV 5.9.2.4 Network: 10GbE RJ45 SQL Test VM created in Nutanix test cluster:- 12 vCPU 96GB RAM CVM size: 12 vCPU 32GB RAM Test Result from MS SQL s

Keep getting an error while trying to deploy Server 2016 on AHV using SCCM. Has anything changed recently? I used VirtIO v.1.1.4. Do you have to have NGT in sccm also?

I'm trying to deploy FortiAuthenticator v5.5 VM but running into issues on AHV. I've tried creating the VM using the files from Fortinet but no instructions when using AHV per this guide: https://s3.amazonaws.com/fortinetweb/docs.fortinet.com/v2/attachments/5795878a-1f78-11e9-b6f6-f8bc1258b856/fac-vm-install-guide-43.pdf The files I've used are the following: KVM - fackvm.qcow2, datadrive.qcow2 Vmware - fac.vmdk, datadrive.vmdk screenshot attached of my options from Fortinet Created vm adding cloned disk using the files above Set vCPU, Mem, added NICs Fortinet suggested I use the vmdk files but still getting the error in the screenshot. I'm new to AHV so any help would be appreciated.

Anyone successfully running Fortinet FortiSandbox VMs on AHV in their environment. The VM itself is able to deploy, but it fails to create its on VMs to test executables on.

Are there any VMware 6.7 "gotchas" that I need to worry about before upgrading? We're on 5.10.2 running on Dell XC series for a little context. Thanks!

I’m planning to move a Windows Server 2012 R2 Datacenter Edition VM from Hyper-V 2012 R2 to AHV on AOS 5.10.2 today. I have created a similar (but not cloned) test VM in the environment and migrated it yesterday with no issues. UEFI worked fine. Today in my final prep I’m seeing that in newer versions of the Nutanix documentation (AOS 5+) that this migration and VM type (AHV with UEFI) is listed as Limited Support and “Not recommended for Production”. Is this a showstopper? Are other customers moving important production Gen 2 UEFI Hyper-V VMs to AHV? Scenario Support Level Generation 2 VM (UEFI) migrated from Hyper-V to AHV Limited support. For information about configuring UEFI for VMs migrated from Hyper-V, see Post-Migration Tasks, Windows VMs. UEFI VM migrated from ESXi to AHV Not supported Note: The support levels in the second column are defined as follows: · Limited support. Nutanix recommends that you not use the configuration in product

Hello all I'm trying to establish the optimal disk layout for a VMware MS SQL 2016 2 node guest failover cluster that will have a single SQL instance hosting multiple small to medium sized databases. Unfortunately we don't really have the funds for licensing to do the recommended approach of creating lot of small VMs to host these databases, so we need to consolidate where possible. I've been reading though the Nutanix SQL 2016 best practice guide and it's raised a few questions. I've decided to allocate multiple vdisks specifically for database files, so I'd have a few database files to each vdisk instead of one vdisk with all the database files on it. I'm assuming this approach might be better due to each vdisk having a 6GB Oplog allocation and so more vdisks would prevent a single oplog from quickly over filling? Is there any there real a benefit here to having more vdisks to spread the databases across or does this only really come into play when you split indi

So over a year ago, there were reports of AHV turbo coming to us in 5.5. We are now at 5.10 and there have been no reports of VirtIO drivers for Windows supporting MultiQueuing. Any ideas as to why?

Wanted ask the community for some feedback on the topic of SQL Server 2008/R2 End of Support. My fellow Nutanix Solutions team members @gregwhite @Chris Paap, myself and others were discussing about SQL Server 2008/R2 End of Support and how that would impact IT? Can you help us by sharing your thoughts, actions, tools around DB/app upgrades, migration etc related to SQL Server 2008/R2? You can take the survey here: https://www.surveymonkey.com/r/VJ2NWXS

A customer asked.... Is there a sort of table to compare the Acropolis version with che KVM corresponding one? Thank you!

Hi , Anyone would know if RHEL is supported to run on Nutanix Acropolis Hypervisor (AHV) ?

The following shows the available Load Balacing options currently available in vSphere 5.5 along with the recommended configuration for Nutanix environments for both Virtual Distributed Switches (VDS) and Virtual Standard Switches (VSS). NIC Teaming & Failover Recommendation

Hi, I just added a new storage disk onto a VM and copied data onto it then realize we'd rather just expand the current one so I deleted the new disk and when I go to expand the current disk it is showing that I have no more space to use to expand. Where is the space going after I delete disks? Thanks,

Hi Team, We use SCVMM to manage all our VM's and we are planning to move some machines to the AHV environment..Can you please confirm whether we will be able to do the live migration my VM's from HyperV to AHV?? Regards, V.Pradeep

Is it possible to implement throttling at a per VM level? The thoughts/scenario behind the question: We have had on a couple occasions where we found a VM (different in each occasion) that was running away with storage controller IOPs. Of course the goal is to get the actual issue resolved for the offending VM, but we would like to be able to implement throttling to be able to assure other VMs in that cluster don't suffer when this does occur. Disk I/O has been the scenario so far, but could also see the need to throttle CPU, memory, and/or NIC throughput at some point.

Hi Everyone, im just cruious about this scenario, I have 3 server type 2310 with single ssd, So if SSD FAIL on 2 different server at the same time what will happening?

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

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)

How do virtual machines on AHV migrate to vmware?

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

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

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.

Hey Everyone. So, I am relatively new to the whole Nutanix game. Im curious what everyone is suggestion is for CVM allocation. We had nutanix do our original provisioning, but the provisions the installer set it up with seem a bit excessive. 10 Cores and 32gb ram per CVM, Any thoughts?
