AHV Virtualization

Hi All-I am in the process of creating some MSCS SQL Clusters on Server 2012R2 . In the applicable documentation in regards to using iSCSI-based VGs with Nutanix. Also read Mike Websters information about hot expaning the disks associated with those VGs in an upcoming software release, really nice! My question is about how I break the I/O over the multiple VMWare P/V SCSI controllers currently. If I followed the instructions in https://portal.nutanix.com/#/page/solutions/details?targetId=BP-2049_Acropolis_Block_Services:BP-2049_Acropolis_Block_Services Wouldn't all the I/O go over the default and only SCSI controller for that VM? I am trying to distribute the I/O for logs, tempDB, etc over multiple SCSI controllers. It was worked well in our environment in which w

I'm new to ntnx and have a what I hope is a simple question. Is it possible to access the nfs data store from inside a vm that is running in the ntnx env? i have a vm that will need tb's of storage but I don't want to create giant vmdks for it. Chris

I've just written an article about the official VMware vRealize Operaitons Management Pack for Nutanix that was published by Blue Medora. If you'd like to check out the management pack and also the content pack for Log Insight, here it is - http://longwhiteclouds.com/2016/09/18/vmware-vrealize-management-packs-for-nutanix/.

Hi all, We have a 3x node Dell XC630-10 Cluster running on AOS4.5.0.2 - Starter License. These nodes are running a Dell Customised 5.5U2 VMware image. I want to upgrade these nodes to a Dell 5.5U3-A04 image build 3248547. This will have to be done manually as we do not have DRS running (Standard VMware license). On top of the image I want to patch them to "Patch 8" level - release date - 04/AUG/2016 (Patch 9 available now). However reading the Hypervisor FAQ it seems that major/minor vSphere releases are supported and QA certified within 90 days of GA. Therefore my question is: After applying the Dell 5.5U3 Custom image then, in theory, I can only apply Express Patch 10 build 3568722- 22/Feb/2016? Comments are much appreciated.

Hi all, I have a requirement with one of our migrated servers to retain its original MAC Address due to licensing. I've migrated the machine only to find these requirements post migration, so the Question is how can I change the VM MAC address? Thanks, Stephen...

I'm running NOS 4.7.1 with vSphere 6.0 and loving the seemless vm migration to the remote site using Metro (for a planned outage). Is there a way to perform a failback just as seemlessly - no downtime? After reading through Mike McGhee's v2.0 Best Practices document I wasn't able to find if this is possible or not.

Hi all, Just wanted to check if anyone else is having issues with PRISM stops collecting CPU and Memory Stats from the Hyper-V hosts themselves. The issue seems to be somewhat sporadic and I havn't been able to Pin-Point any specific operation nor any specific time. Restarting the NutanixHostAgent helps to resolve the issue until it stops collecting again. We are currently running 4.6.1 and are using Logical Switches that perhaps might be one of the problem. When this happends the Runway function in Prism Central stops working properly so while it is a "cosmetic" issue it still affects other functions inside of other Nutanix Functions. Kind Regards

I've had an intermittant problem with some 2012 VMs I had migrated that have been locking up after a random time, usually going to 100% CPU and all IO stops. VM Console is unresponsive and network not reachable, reset is only solution to bring back online. It would then run again for a number of minutes, hours, even a day or more only to do same thing again at a random time through day or night, so was no logical patten to it. I endup tracking it down to a timezone config issue, when rebooting the VMs in question the timezone would set their clock to the hypervisior host time, which was in a different timezone (default TZ nodes were shipped with) to the the host VM TZ. I had a similar problem in the past, although not with the host lockups, where a number of hosts would lose time sync and be out by the TZ difference between host and VM on our Citrix XenServer Cluster hypervisor host. Because our VM are on an AD domain they will be out of NTP adjustment range becasue t

Does anyone have some experience with running SAP on Nutanix, doesn't matter if it runs on HyperV or VMware. Oracle or MS SQL is ok. Just looking for some feedback and best practices. Kind regards Bart

Hi Does anyone having experience or recommendation for tuning Postgresql Server Workload on Nutanix? We followed the Nutanix SQL Server Best Practices and Micheal Webster's Recommandations for vDisk and LVM layout at: http://longwhiteclouds.com/2014/11/27/performance-testing-mysql-and-postgresql-with-hammerdb-and-pgbench/ Unfortunately, the Performance does not meet our expactation compared to our old PostgreSQL server running on a NetApp Filer. Out Setup: 3 Nodes Nutanix Cluster NX-6035-G4 with 1200 GB SSD, NOS 4.6.11 vSphere 6

Running DELL XC630 5 node cluster with ESXi 6.0 / NSX Trying to use One Click Upgrade to move from NOS 4.5.2 to 4.6.2 PreUpgrade Check fails with "Failed to connect to Hypervisor managment IP X.X.X.1 Failed to connect to Hypervisor managment IP X.X.X.2 Failed to connect to Hypervisor managment IP X.X.X.3 Failed to connect to Hypervisor managment IP X.X.X.5" x.x.x.1~5 being ESXi IP External addresses - SSH to all ESXi from all CVM on both Internal and External IP works. (also the reverse connection is working) - ESXi reboot / Genesis restart done - fix_host_ssh done - even updated all ESXi root password on CVM (even though unchanged just to be sure) - No Alert/Warning under PRISM - ncc health_checks run_all came out with flying colors. - Identical setup at DR site having same issue/symptoms tail -f genesis.out shows: esx_utils.py:135 Connection to host x.x.x.1 failed x.x.x.1:443 is not a VIM

Apart from listed pre-requisites before starting Hypervisor Upgrade (ESXi) listed below, had to Disable Affinity Rules under DRS to enable ESXi host go into Maintainance mode and continue update. Got stuck since i did found this part the hard way... 1) Genesis.out log pointed the target CVM owning Shutdown token and not letting it go. 2) Then from vCenter: Manual Shutdown of CVM -> Manually put related ESXi host in Maintainance mode -> Exit Maintainance mode -> Start CVM 3) Go to PRIMS and upgrade continues... and so does 2048... - Koji

There appears to me a Management Pack for SCOM 2012 available now http://myvirtualcloud.net/?p=6687 but I cannot find it. Can anyone pls help? Thx, John Bradshaw

Good day, Quick question regarding Exchange on Hyper-V, I havn't been able to iron out all the questions regarding the support for Exchange on Hyper-V where the .VHDX files resides on the backed SMB3 part. From a Microsoft stand-point they support .VHDX files on SMB3 as long as it's backed by block storage, but I havn't been able to verify that Nutanix actually goes under the "Block-Storage" part, on my own mind it should. There are a few documents where Exchange on Hyper-V is mentioned, and in those SMB3 and iSCSI are both mentioned but no on what part (SMB3 for OS, iSCSI for Databases or in fact VHDX on SMB3 for databases also). VMWare is rather straight forward, Volume Groups to be fully supported by Microsoft, period. But what is the stand-point regarding Exchange on Hyper-V where databases are .VHDX on SMB3 from a Microsoft and Nutanix perspective? Kind Regards

Hi, Is there any way that we can monitor a particular VM activity - log file from Nutanix perspective. we keep on getting VM to be rebooted. VM OS: Windows Server 2008 Hypervisor: AHV

I found a problem that can not type a full stop symbol into User VMs under acropolis hypervisor but if I uesd a remote desktop connect to those User VMs It's available a full stop symbol I want to know that in this case it is a problem with IE or AHV.

Hello folks, I installed a 3node cluster with hyper-v on 1Gig interfaces. Now I want to "migrate" this setting to 10gig interfaces. If i disconnect the 1gig interfaces and plugin the 10gig interfaces the host disconnects and no services are functional. I have to disconnect the 10gig interfaces and reconnect the 1gig interface to reach the host/cluster. Is there a document which describes the procedure to change 1gig to 10gig interfaces? Or could anybody give me some advice? If i check the nic teaming on the hyper-v hosts there are 4 interfaces (2x1gig, 2x10gig) added to the NetAdapterTeam. Best regards, Freddie

Planning a customer migration of 15 physical servers and looking for supported options of P2V.I see links to the Sureline 3rd party tool. Is that the only direction or anything native from Nutanix yet.

Hello, I have had no issues building Microsoft Failover clusters using volume groups, vDisks, and MPIO; the procedure is very straightforward. Now I want to clean up a few test configurations and remove unwanted clusters, but I'm not sure of the best approach. How do I: List and remove attachments List and remove vDisks List and remove volume groupsI'm sure it's all in the acli; I'm hoping someone has already written a procedure. Thanks, Scott

I've been going through the nutanix SQLServer best practices guide and was wondering how relavent it is for AHV? mainly where it refers to different drives on different SCSI controllers? Regards, Stephen.

CIFS is supported via Hyper-V currently. Rumor has it that native CIFS for the NTNX File servers is scheduled for the NOS 4.6 release. Is there any pre-GA information on this?

Hello friends, I am new here nice to meet you and I hope you can help me.I am working with two Scenarios in my client. One we have Nutanix on its Linux KVM-based hypervisor and the other we have common x86 servers running VMware.The objetive is compare both solutions and decide what's best. (we want Nutanix to the best of course!)The application running on both of them is a jBOSS system, on 3 virtual machines. (application, DB and one apache front end.)I created a recording test using jmeter, where the user makes a lot of steps in the web interface (for instance, search for a specific person, click on the menu, etc). The test runs fine on the x86 server and VMware, but on the Nutanix, after 150 users, I always get: Started: 0 Finished: 0. And also the CPU Usage is higher than the other scenario. Almost the double.I added more CPU and RAM to the virtual machine, but it didn't work. I am also running on non-GUI mode, removed the listeners, added more memory to the "MaxNewSize", but nothi

Greetings community members! I am brand new to the Nutanix platform and have completed my basic initial configuration of my nodes on ESXi 5.5U2, however I am having trouble finding (not through lack of Google-fu) a complete guide on what Nutanix recommends as BPs for configuring hosts for ESXi. This raises some questions... e.g: Should I add anything to my node's Advanced Settings? Should I chanage the power settings Active Policy to High Performance? What is the definitive guide to HA settings with respect to the nodes, VM monitoring, policies therein, etcetera ? Not that this is an exhaustive list of questions, but I forgot to ask our Nutanix Pro Services rep before he left...and I could not immediately find what I need unless I am looking in the wrong place! :$ Edit: Some of what I asked is in the

Hi all, My present client is making me working on a design implying to deploy a XAAS plateform with a lot of security inside (NSX is on the cook list). In our team, i was declared as the nutanix man. My mission is to determine the best way to isolate storage from diffrent workload : we'll have an integration zone, a developpement and a production zone as PAAS. Some node will executed heavy VDI (K2 graphic cards will achieve this), Then we'll have a IAAS with vcloud SP for the sandbox zone).So we can imagine some sort of multicluster with 3 cluster dedicated to 3 zones : 3D VDI zone / SANDBOX IAAS zone / and PAAS zone. It implies at least 9 nodes which is a bit too much for starting plateform. My question is, can I make a 6 node cluster for nutanix / storage point, with 3 volumes pools on all 6 node ? and more than that what will it implies in terms of storage performance, data protection, data seggreg

Hello all, I'm wondering if there is anyone out there using Nutanix with KVM as a hypervisor, and if so, what kind of management do you use for daily VM related admin jobs? - virsh/virt-manager ? - RHEV/virto ? - OpenStack on top? - other "cloud solution"? - custom tools/scripts ? Please share :) I'm quite curious about official / eventual cross-vendor support and/or "show-stoppers" you might have experienced or enlightenments you might have had.. P.S..: *psssst*...rumours have it, that Nutanix themselves are developing some "management tool" for KVM..anyone knows more?
