Official support date for vSphere 5.5/5.5U1

Hello everyone, Does anyone have an official date for the support of vSphere 5.5? And with 5.5 update 1 right around the corner (next month or so), do you now if the U1 version will be supported on the release date or will we need to wait some more? For what it's worth, our block is running fine in 5.5 since ~1month (although unsupported by Nutanix, we updated it with VUM without problem). Thanks in advance for you answers, Sylvain.

Windows Server Patching

I am looking for a patching product that will tie into Nutanix and be able to take a snapshot before patching, we are looking to automate this process to get away from manually taking snapshots prior to deploying patches. We do have Protection Domains setup but with the timing intervals it is not ideal only use those pre-deploy as they can be hours behind the actual patching deployments. If anyone is using a product that has this capability please let me know or if you may have a better way to accomplish this within Nutanix.

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?

Error adding HyperV feature on Server 2016

Attempting to add the Hyper-V feature to a fresh Server 2016 VM. I receive the message: "Hyper-V cannot be installed because virtualization support is not enabled in the BIOS" After picking through some very limited search results I attempted to modify the VM using "cpu_passthrough=true", however the error remains. Any advice to get this working? Thanks Andy

SQL Licensing - Moving From ESXi to AHV

I’m in the process of migrating from VMWare to AHV.  I was curious if there are any licensing changes in regard to SQL.  Do I need to just make sure that I have enough core licensing to run the actual VM or do I have to buy core licenses for every core on my entire 4 node cluster?  I heard of something called infinity that I could use to keep my VM on just one node?  Thanks for your help!

2012 VMs intermittently locking up resolved

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 time differen

ESXi5.5 Upgrade and patch installation - Supported-QA vertified

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 [url=http://www.nutanix.com/support/support-faqs/#hypervisor-support]Hypervisor FAQ[/url] 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.

NTP time sync in cluster consisting Hyper-V compute nodes and AHV storage nodes

Hi, I have a customer who is having a cluster of 11 Hyper-V 2016 compute nodes and 2 AHV storage nodes. During a NCC health check, there is an error mentioning that the 2 AHV nodes are not syncing with any NTP server. The current NTP time sync setup is something like this.   Nutanix cluster (Hyper-V and AHV) → DC → NTP source   First question, how should we begin troubleshooting the issue? There is no remote access for our support to perform a webex session troubleshooting due to security.   Second question, customer is changing the NTP source. This new NTP source is 1-2 mins behind. Any impact if customer proceeds to update on the DC? Does the cluster auto sync up    Third question, at what time intervals does the nutanix cluster probe or sync up with NTP time?   Regards, Leonard Thng

Copy or Storage Vmotion Very Slow

I have a 8 nodes nutanix with vSphere 7 deployed. I’ve created 2 new storage container with compression enabled and map to the nodes. I test to copy the file that i uploaded to the default container to the new storage container presented as NFS datastore...it was very slow. 5GB took 2hrs. Then i tried storage vmotion of a VM reside on the new datastore to another new datastore. A 10GB VM took 20 minutes. If storage vmotion from the default container to new datastore, it fails.

vServer LACP Issue

Hi there,        I’m a network guy and this is my first time post here. Sorry if I broke any forum rule. We are having some issue with vServer host on Nutanix, and I would like to see if any experts here can tell the solution of the problem from nutanix stand-point. We have nutanix setup as LACP and connects to two nexus switches(5000) by using virtual port-channel. Sometimes mac address of vServer showed incomplete on arp table in one of the switches, not only one vServer. Then we finally realized that if we shutdown one port of the switch, which mac address incomplete in arp table, the vServer started to work immediately. After we executed no shut, the issue was back again. We checked the issue from switch stand-point, but couldn’t find any issue. Is anyone know the issue can be related to Nutanix? Thank you.

Is Hyper-V Generation 2 UEFI a showstopper for Production VMs?

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”. [b]Is this a showstopper?[/b] Are other customers moving important production Gen 2 UEFI Hyper-V VMs to AHV?

Server 2012r2 CHKDSK /SDCLEANUP crashes VM Everytime

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

Redundant Windows based file server on Hyper-V

Hey there We have a Windows Azure Pack environment deployed on a Nutanix Hyper-V based infrastructure. The infrastructure is build with high availability in mind: [list] [*]Redundant Virtual Machine Manager configuration [*]Redundant SQL Server configuration (using SQL Server AlwaysOn)[/list]But we are currently facing an issue setting up a redundant VMM Library Share. Microsoft does not allow using a redundant VMM installation as the Library Server. Instead they recommend to setup a Scale-Out File Server infrastructure as the Library Server and then add your Library Share to it. However, to my current understanding, it is not possible to setup a Cluster Shared Volume on Nutanix Hyper-V - which is a requirement for a Scale-Out File Server. What are the design recommendations from Nutanix in this matter?

Enabling or Disabling Console Support for vGPU VMs

Enable or disable console support for a VM with only one vGPU configured. Enabling console support for a VM with multiple vGPUs is not supported. By default, console support for a VM with vGPUs is disabled.To enable or disable console support for each VM with vGPUs, do the following: Run the following aCLI command to check if console support is enabled or disabled for the VM with vGPUs.acli> vm.get vm-nameWhere vm-name is the name of the VM for which you want to check the console support status.The step result includes the following parameter for the specified VM:gpu_console=FalseWhere False indicates that console support is not enabled for the VM. This parameter is displayed as True when you enable console support for the VM. The default value for gpu_console= is False since console support is disabled by default.Note: The console may not display the gpu_console parameter in the output of the vm.get command if the gpu_console parameter was not previously enabled.

VGLB and AOS 5.6

As the most of you probably know, with AOS 5.6, has been introduced the Volume Group with Load Balancing function, well known as VGLB As i know the 5.6 version is in short term support. Now i'm deploying a two Oracle 12c RAC clusters on 2 8000 6-nodes AOS-AHV clusters with AOS 5.5.3.1. It involves using volume group with multiple vdisk, network related configuration, Linux related tuning and so on... Of course, with 5.5.3.1 (so far the latest GA version in long term support), i've not the VGLS choice, every volume group's I/O is managed by a single CVM. By the other side, with AOS 5.6, i could distribute this load on every single CVM and every single node storage on the cluster. Of couse this heavily impact on the resiliency, the performance and the resources distribution. The questions are two and i need some suggestions. 1) could be better to upgrade to 5.6 even if it is in short term support? 2) is it possible to update "on the fly" the volumes's configuration with "vg.upd
