VM network Troubleshooting

Hello, If you use balance-slb, how does one figure out which physical is being used by one VM ? For instance, with ESXi I’d run esxtop, and I can see which physical nic is being “mapped” to my virtual nic. Is it possible with AHV? If yes how ? I think it is important when you troubleshoot.

ESXi | CVM shows 100% memory usage at all times in prism.

You might have noticed a 100% CVM memory usage in the Prism Element or high CVM memory usage alarms in vCenter. In vSphere 6.5 and later, this issue is seen with virtual machines configured with PCI pass-through devices. Symptoms: In the vSphere Web Client: CVMs trigger the Virtual machine memory usage alarm. The VM's Memory Usage/Active performance metric is continually reported as 100%. In Prism Web Console: CVM Memory Usage % is permanently shown as 100% There is nothing to worry about as this is just a cosmetic issue and has no effect on the CVM performance. The NCC health check report will not include any errors or warnings regarding memory usage. Similarly, o alert will be generated in the Prism Element. To take a detailed look at why ESXi displays CVM memory usage as 100% and the solution for the above, take a look at CVM Memory is 100% in Prism and Web Client with ESXi 6.5 or later

AOS 5.10.9.1 LTS - Error creating image from URL using PE, acli and REST API

Hi all I´m attempting to create one disk image from http server (I know that NFS is preferred) but i got errors from PE, acli and REST API. AHV, CVM, PE, PC and the web server are one the same network (then I can exclude routing issues) and on the web server (Centos 7.7, apache httpd-2.4.6-90) firewall and selinux are disabled and the url is called using IP to avoid dns issues. The content is available via wget but the image creation command ends with error 503 (Service Unavailable) while on the web server with log at debug level nothing is written on error and access log. I have tested also to stop httpd and use python -m SimpleHTTPServer 80 but doesn´t work (I got one excepction that I cannot fully read and I don´t know where is logged) What´s wrong? I´m missing something? Someone have a suggestion? Here some operation samples: Download test using wget to check http service ~~~ nutanix@cmv:~/tmp$ wget http://192.168.158.40/images/gm-back-test-001-scsi1.qcow2 --2020-03-17 16:

Nutanix space reclaimation

Hi Team, We are running few file servers (windows 2016 machines) which are running on Nutanix + VMware 6.5. For e.g. i have a 5TB VMDK attached to the VM which is holding up a lot of files (being a file server). Now when we check the size of this disk in VMware, we this as around 4TB consumed (similar figures in Prism as well). However within Windows, the actual space consumed is only 1 TB. The question is - how do we reclaim this space to match up the numbers seen by OS with what VMware believes the used space is. (i have seen some posts where users have mentioned using sdelete etc. but it isn’t really a scalable solution) Thoughts ? Thanks. Ravi

Best way to power down an Hyper-V cluster for extended time or relocation

Are you going to have a planned power outage or relocation procedure that needs to shut down your Hyper-V cluster safely? Maybe you have experienced this situation: We have a scheduled power outage at this location for Dec 31th. We are going to need to power everything down prior to the outage. What is the best way to safely power down the Hyper-V cluster? With Hyper-V Clusters it is important to consider the following procedure before shut down all the user VMs in the failover cluster : Make sure that you have at least one domain controller running outside of the Nutanix cluster. Otherwise, you will not be able to start VMs after powering on the cluster. Make sure that the Hyper-V hosts are configured to use this external DC/DNS server. Disable all Metro Availability-enabled Protection Domains, and make sure no on-going replication is happening. Consult the article Disabling Metro Availability for more details. To check the complete procedure and the details follow through to th

100% CPU Usage on all my hosts

In the last few weeks we have been experiencing complete host CPU usage at 100% on all of our host(6 of them). We were never this high. When the system is at this level no one can do much on the ystem for a few minutes. The biggest change we did was add Bitdefender Gravity Zone to our system. We have about 650 VMs on the system. Memory usage hovers between 50-60% on all the hosts. We are running ESXI hypervisor with VMware Horizon to run our VDI system. Anyone have an insight into this situation? Is there any tweaking I need to do? What could be causing this?

Download AHV image/vm disk from AOS 5.10 - scp error on port 2222

Hi all, I´m attempting to download one image from a cluster on port 2222 as described on many documents (i.e. AHV | How to access VM disk files on Nutanix container or Copy files to/from a containter ) and I have a strange issue: using Filezilla or Winscp it works fine, using Centos 7.7 Linux scp doesn´t work. A syntax as “scp -P 2222 admin@VCM-IP:/default-container-171248/.acropolis/vmdisk/image-or-disk-uuid” accept the password and then terminate with error “exec request failed on channel 0” On the linux side firewall & selinux have been disabled a scp to other systems works fine. Any suggestion?

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!

What organizations lose when not chose Nutanix as the Hyper-Converged Infrastructure (HCI) Solution – Part 1

Technology landscape is changing rapidly, and IT teams in organizations should embrace the newer technology at the earliest as it would be refreshed in no time. Meanwhile, there are some technologies which are making their presence felt and getting enough attention that every other vendor is willing to launch or have a me-too product irrespective of its [b]Reliability, Availability, Serviceability,[/b] and[b] Scalability[/b] features. The technology is Hyper-Converged Infrastructure aka HCI. The organization coined and pioneered this is Nutanix Enterprise and a product initially good for running Virtual Desktop Infrastructure (VDI) Solutions has become de-facto standard for all kinds of virtualization workloads be it VDI, Remote Office Branch Office (ROBO), Business Critical Applications (BCA), or similar virtualized workloads.

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.
