AHV Virtualization

We have a fresh Windows Server 2012R2 VM that we ran CHKDSK /SDcleanup on. After running for a period of time, the server VM turns off with no errors logged other than the fact that it was an unexpected shutdown. At first we thought something was corrupt, and since it wasn't in production yet we decided to just recreate the VM from scratch. Immediately after creating the new VM, we ran the same command and got the same results. It crashed while running on the C: drive running on boot up as well as on the 4tb data drive with zero data on it yet. So far we have been able to duplicate it everytime. We have a Xen Server with a Server 2012R2 VM on it and there is no issue running this command. Any ideas? Driver issue? Thanks Steve

Buddies, Good morning! What I wonder to know is with docker swarm cluster runs on nutanix in detail. Can Acopolis container service support swarm or only support rancher? Thanks. Ricky

Hi All, Just wanted to let you know that using traditional SQL failover clusters and SQL FCI, or any MSCS / Microsoft failover cluster is available in tech preview as of NOS 4.1.5. This is because we have introduced SCSI 3 Persistent Reservations to the iSCSI stack. To implement a cluster you need to use the MS iSCSI Initator and the Nutanix Volume Groups contract and iSCSI target for in-Guest iSCSI access. This will become a full GA feature in an upcoming release of NOS. Please experiment with it and let us know your thoughts.

Hi Expert, I plan to relocate my Nutanix Box to another rack. can someone help me or guide me the proper procedure for this activity, below the details Hypervisor: ESXi 5.5 Nutanix Box: 4box Node: 16 node How can I perform the proper shutdown. I a bit confuse with some article from google

Hello All, I am new to "Nutanix XCP, One basic question regarding the Raw device mapping in Esxi using the Nutanix infrastructure. Is RDM mapping supported in the Nutanix Appliance4.6 (Nos)? If yes, Can you please share the procedure to Create a RDM (Physical mode)?.. Thanks, Bhoopathy

G'day one and all, We're a new nutanix site and have been migrating machines from our previous HyperVisor over to Acropolis/KVM. Our older servers have been no problems at all, 2003 and 2008 servers. however all our 2012R2 servers are having problems where the storage drivers are not being seen. To test I have tried a new install ont a VM from install DVD. Driver load screens comes up and I point it to the correct location on the nutanix VirtIO drivers ISO image. All drivers are seen, i.e. shows the correct drivers to load, but when selected and goes to load the drivers, and error stating "No new device drivers were found. Make sure installation media contains the correct drivers" The VM Disk is configured as scsi Regards, stephen...

Dear Community, I have an issue. I'm installing a Windows 2008 standard (not R2 nor SP1) on a AHV cluster and then I need the virtIO drivers. It works fine for the iSCSI passthrough driver and the baloon. But the Networking adapter is failed. It says drivers are not signed and cannot be verified, I bypass the warning and then it says there is an error, driver corrupt blablabla. I have tried the latest Nutanix virtIO without any luck - whatever OS version, they all failed. any magic idea ? Thanks 😉

Hi all, I created a document describing how to upgrade ESXi on the XC platform for a customer. It uses the Dell iDRAC specifically. If anyone has feedback on anything that was missed or could make things easier I'd appreciate it.

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.

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.

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
