CVM leader only wants to use itself (.LOCL) as time source

I have been trying to chase down and eliminate this error for a while now. The cvm leader only wants to use itself as the time source - when I run this command  (allssh ntpq -pn)  it shows      remote           refid      st t when poll reach   delay   offset  jitter==============================================================================x.x.x.x  y.y.y.y    2 u  603 1024  377    0.337  55090.5 419.722x.x.x.x  184.105.182.16   3 u  200 1024    4    0.358  75064.8   0.000*127.127.1.0     .LOCL.          10 l  587 1024  377    0.000    0.000   0.000 (The asterisk indicates that it is using itself as a time source, is that correct?) I can run ntpdate successfully to the configured ntp servers and the cvm can connect to them.  (I can even run ntpdate to an external time server that is not configured for that matter)   How do I get the cvm leader to use the configured ntp servers as the source (and not use itself)?

Hyper-V Collector output causing error on import

Collector 3.5.1, Windows version. The customer has collected the data from a 2-node Hyper-V cluster and I can open the excel and browse through it - it looks right to me, I see all the VMs etc. When I try and import into sizer, I get “Some unknown error occurred”.  Any ideas?  There’s nothing particularly strange or unusual in the data that I can think of.  In the meantime I will probably try and manually add the equivalent workload. Thanks, Allan.

Nutanix CE installs but CVM does not create cluster

Hi,I followed this guide:Installing Nutanix Community Edition (CE) on vSphere 7 - Derek Seaman's IT BlogTo test a install of AHV/Prism CE and the AHV host installs fine but the CVM can not get to the outside world or ping ip’s.I can ssh to the CVM from the host on the correct IP and do the one_node_cluster create command but it just fails with `Failed to reach a node where Genesis is up` if I do `genesis start` it gets past that but just hangs after it starts up some services during the create.I tried not checking the one_node_cluster option in the install and doing it manually afterwards, but I get the same results.Happy to provide any info. The gateway etc look fine in the `/etc/sysconfig/network-scripts/ifcfg-eth0` file

Vendor image that needs the machine type to be Q35?

We are running an image from HPE Aruba for a Mobility Master that crashes daily. The error is an IRQ interrupt:User: [14730.377720] irq 27: nobody cared (try booting with the "irqpoll" option) [14730.378230] handlers: [14730.378461] [<ffffffff813be5d0>] vring_interrupt [14730.378717] Disbling IRQ #27I’ve been directed by the community that there is a KVM fix for this by changing the machine type to Q35. I can see in the acli documentation there are settings for machine type but I can’t seem to find a list of acceptable settings that I could use there. I was hoping to perhaps create a VM through the acli with this already set or perhaps update a VM (is this bad?)Perhaps it would look something like this:acli vm.update machine_type="pc-q35"

Upgrading sequence AOS, NCC, Foundation

Hi Team, I will be carrying out upgrades tonight at 8 pm GMT and want to plan before hand: can I please get urgent assistance: I understand that I can jump from AOS 5.15.6 LTS to 6.0.1.1 directly but before doing this I want to confirm below: The order I can see is to upgrade Foundation 1st: we currently have foundation-4.6.2-6e9b7fc8 version can we directly jump to 5.0.4 version of foundation? or we have to install from older base versions one by one to reach 5.0.4? NCC 2nd: we currently have 4.1.0 can we jump to 4.2.0.2 or we have to install 4.2.0.1 first?

Expand 1 node cluster

Hi everybody,In this moment, I have a 1-node cluster AHV, but in a few months this cluster will be expand could be with 1 or 2 nodes more.May I expand to 2-nodes cluster? If it is possible Is necessary a witness VM?If I have the opportunity, I think buy other 2 nodes, I think that I will not have issue expand from 1-node to 3-nodes cluster. Are I right?What do your recommend in both scenarios?

NIC not showing up in VM

This seems like the place to post this, so please tell me if I need to move it.I am trying to setup a lab with a Nutanix G3 3060 cluster running 5.15. Using AHV, which I don’t have a lot of experience with. I think I am having a networking problem. For lab I’m only using 1GB connections.On each link I have a native or untagged VLAN which the CVM’s use. I also have several other Tagged or Trunked VLANs that I want to use for other purposes in the lab.The CMV’s are fine and the cluster comes up no problem. It has some complaints like NTP and the like, but it is otherwise good.Under networking I added the other VLANs and their VLAN IDs.I then created an OPNSense VM and gave it 2 NICs. One on the management VLAN. The same one the CVM’s use that is native. Then a second NIC with one of the tagged VLANs .I have verified that both NICs are set to connected. I even tried adding a 3rd. The management NIC (untagged) comes up and I can access the VM, but the other one won’t. OPNSense is reporting

Nutanix Task Log Size - Tracking down power actions

We are running a Nutanix AHV / Citrix EUC environment.  We are currently chasing down a problem where we are being told by our Citrix team that machine power on requests are taking 4 - 5 minutes at times.I have asked for specific examples, and the examples I have seen - when looking at the acropolis.out log - show the task for power actions taking 7 seconds to complete.A missing piece here is that the acropolis.out log is showing when the task is being executed but I don’t see where the task request came in.  Following this article: https://portal.nutanix.com/page/documents/kbs/details?targetId=kA00e000000Cq9eCAC I see it clearly documented on how to track down the task. However, our task log shows like, 500 tasks.  Is there a limit set somewhere? It seems like the log is for a very short window.  When I look up the task ID, I get no data at all.  We have 10,000 VDAs so, during a busy time, 500 tasks flush out in minutes, if not quicker.

Minimun VM witness requested

HiI would like to know which is the minimun VM witness that I need for an specific scenario with several sites and 2-node cluster on each site. At the following article I see this:You can register multiple (different) Metro cluster pairs to a single Witness VM. One Witness VM can support up to 100 instances, that is the combined total number of protection domains in the registered Metro cluster pairs and the number of registered two-node clusters. (A single Witness VM can support both metro availability and two-node clusters.)https://portal.nutanix.com/page/documents/details?targetId=Prism-Element-Data-Protection-Guide-v5_18:sto-metro-availability-witness-c.html However at the following post I see this: You can register multiple (different) Metro cluster pairs to a single Witness VM. One Witness VM can support up to 50 Witnessed Metro protection domains distributed among its registered Metro cluster pairs.https://next.nutanix.com/installation-configuration-23/metro-availability-witness
