ESXI 6.5 lowering syslog logging levels (again..)

November 23, 2016, 11:43 am

Hi,

 

there were a couple of discussions about configuring the syslog logging level of an ESXi server. So, I we all know these links:

 

Enabling trivia logging in VMware vCenter Server (1001584) | VMware KB

and

vSphere Documentation Center

 

But I still have some issues in reducing the 'verbosity' of an ESXi 6.5 host:

 

In my config.xml in /etc/vmware/hoistd I have this code. My understanding: "Only syslog messages 'error' or more severe"

 

      <!-- default log level -->

     <level>error</level><!-- <level/> -->

 

 

      <!-- If true, logs to syslog -->

      <outputToSyslog>true</outputToSyslog>

 

 

      <!-- syslog configuration.  Only used if outputToSyslog is true. -->

      <syslog>

         <!-- syslog identifier to use when logging -->

         <ident>Hostd</ident>

 

 

         <!-- syslog facility to use when logging -->

         <facility>local4</facility>

 

 

But I still get syslog messages like this:

2016-11-23T18:40:48.222Z vmh-01.samos Hostd: trivia hostd[9E40B70] [Originator@6876 sub=Snmpsvc.http.HTTPService] HTTP Response: ....

2016-11-23T18:40:01.722Z vmh-01.samos hostd-probe: info -[7F9E980]

 

So, any explanation why this is the case?  Any other configuration file?

 

Or are these options overwritten somewhere?

 

Thanks for refreshing the discussion here.

 

Best.

Hi,

 

what does a syslog message like this mean:

Hostd: [LikewiseGetDomainJoinInfo:354] QueryInformation(): ERROR_FILE_NOT_FOUND (2/0):

 

We get a lot of them from all different ESXi servers.

 

  • Which file was not found?
  • Why?
  • Any method for debugging this?

 

Thanks for any insights here.

 

Best.

 

PS: This is ESXi 6.5 updated from 6.0/5.x etc.

Can you tell me your physical switch vendor? And sorry, but I didn't understand what you mean with "just a bit more information were a running the server of a switch connected to a switch". Are you tell me that the switch where your server (ESXi host) is connected have another physical switch connected?

 

If your switches are Cisco, just post the port configuration and I can confirm if you're using Port Security or not.

The ESXi host is connected directly to a switch, this switch is then connected to another switch across the building. and both switches are cisco but we dont currently have access to the port config

Thanks for your help, We moved the Host to the main switch and it works fine, so the 2nd switch was faulty.

Re: ESXi 6.0 boot stuck on iscsivmk_StartConnection

It was actually due to the partition that holds the "Store" folder, that I deleted by mistake at some point when configuring coredump.

 

I booted on a GParted live CD, rebuild the partition with the right partition number, copied the store folder from another host to it and it was fixed.

 

Quite a fight.

So, if you search for "LikewiseGetDomainJoinInfo" you'll find only one hit which seems related: https://sflanders.net/2015/03/18/vsphere-6-0-syslog-gotchas/ But also is not resolved (see comments at the end)

 

@VMWARE: Anyone at least able to tell where us where "LikewiseGetDomainJoinInfo" is coming from so we can try fixing ourself?  This error is spilling our logs and we would like to eithter fix it or 'silence' it!

 

Thanks.

Boot from a ISO-image not possible if stored on NFS

December 1, 2016, 12:59 am

Two data-sources are configured inside of a ESXi 6.5 Hypervisor:

- a NFS (from a NAS)

- a VMFS on local HDD.

 

Within the ESXi web-interface it is possible to browse inside of both data-sources and also copy files between both sources.

 

 

But when trying to mount a ISO-image from the NFS to an emulated CD-ROM drive, it is not possible boot from this drive to install the OS on the virtual machine.

Also entering the boot-menu and selecting explicitly to boot from CDROM does not work.

 

Copying this ISO to the VMFS on the local HDD and changing only the ISO-position in settings solves the boot problem.

 

Why is it not possible to boot from a ISO stored on the NFS?

I've heard that The US military (or was it the NSA?) consider the VMware hypervisor to be secure enough to run both DMZ and inner zone VMs on the same hypervisor. Can anyone point me to sources that confirm this?

Re: ESXi Patches / cumulative

I know this thread is a bit old but I`d like to share my point of view on this. The confusion in the subject comes down to what one understands by "cumulative". For me it means that specific zip file I download includes all the fixes to all packages (VIBs) released since GA. So the way I see it:

  • Patches are not cumulative
  • Updates are cumulative

It`s clearly stated in VMware KB2083707.

 

Now I`m wondering if there is a way to manually combine several patches into one? This would save me some reboots.

Re: Enable USB device on VM

> On the host I see this USB3 device. It seems it doesn't support Passthrough. I assume it means it will not be possible to see this from the VMs.

 

user9922, you appear to be confusing PCI passthrough and USB passthrough.  You are correct that passthrough of a USB 3.0 host controller as a PCI device is not supported.  This is true for any host controller or hub.  USB end devices can be passed through.  In your case all of your USB devices appear to be attached to USB 2.0 ports.  To passthrough a specific USB 3.0 device other than a hub or host controller please try the following:

 

1) Add a virtual USB 3.0 host controller to your VM.  This is a virtual device just like the USB 1.1 and 2.0 host controllers that you already have.

2) Ensure that the USB 3.0 device is attached to a USB 3.0 port (i.e., a blue one)

 

From your original lsusb output the USB drivers are reporting that all devices are on a physical USB 2.0 bus.  The "root hub" is in fact the host controller.

 

[root@localhost:~] lsusb

Bus 001 Device 004: ID 045e:0752 Microsoft Corp. Wired Keyboard 400                                    <<<<< Device on bus 001

How to improve the performance when use VMXNET3 RSS and DPDK?

Hi expert,
Firstly, I'm not sure is it right to post it here, if not, please help to move to the right forum, thank you!

In our application, we use vmxnet3 vnic and dpdk to process large amount of packets, we want to improve the throughput of the application.
I heard about that RSS could improve the performance of vmxnet3 vnic, so I first try with pktgen and DPDK sample l3fwd(which support RSS native).

 

Here is my test result, and from these I didn't get any positive result.
Port Num    Queue Num/Port    Thread Num    Thgroughput(64bytes)
2                 1                              2                     1.4Mpps
2                 2                              2                     1.36Mpps
2                 4                              2                     1.36Mpps
2                 8                              2                     1.33Mpps
2                 2                              4                     1.31Mpps
2                 4                              4                     1.3Mpps
2                 8                              4                     1.28Mpps

Before test, I have added some print to verify that the packets are distributed in different queues.

 

I have set the RSS option in host, here is the setting:
[root@109:~]  esxcfg-module -g ixgbe
ixgbe enabled = 1 options = 'RSS=4,4,4,4,4,4,4,4,4,4'

 

The VM is deployed through vCenter.
And I have set the advanced option in VM, which are;
ethernet1.pnicFeatures=4 ethernet2.pnicFeatures=4
ethernet1.ctxPerDev=1 ethernet2.ctxPerDev=1

 

So I don't understand why there is no performance improvement?
Is there any configuration missing or my test scenario is not reasonable?

 

Any reply would be appreciated!

 

BR.

boot from ISO Vmware Vsphere 6.5 Hypervisor

hi,

I am trying to find an option to boot from ISO on my second VM. Due to Hypervisor 6.5 free version limitation I cannot edit it over Vshere client. So I logged in over web interface and there are 2 options: 'host device' or 'datastore ISO'. I could not upload it to datastore due to ISO file size 3.5 GB (Windows 2012r2) halfway through it stopped. When choosing host device it shows a message under: 'Client CD/DVD devices are not supported when using the VMware Host Client. If you wish to use a client device, please use the vSphere Web Client.

This device will be ignored.'

 

How else can I load from ISO to install windows 2012 on my second VM? Is there a command line over SSH to mount it by chance ? Or the only way is to purchase a license with extended features ?

Afaik the file size limitation for uploads only occurs with Internet Explorer. Please try another browser.

You are on the right track. You need to upload the ISO to your datastore then select the "Datastore ISO" option and select the required ISO file.

 

If you are having issues with a browser upload you can also enable SSH on your host then connect via WinSCP and upload the ISO via WinSCP GUI. The path to the datastore is /vmfs/volumes/[datastore name]/. I usually create a new folder in the datastore to store any ISOs I need.

Moving to VSphere from Hyper-V

December 30, 2016, 5:48 am

Hi all, I am pretty new to VMWare so I hope I am posting in the correct place.

 

In my previous job we had a few clients running VSphere, but I never really got much of an opportunity to play with it because for the most part it just worked without issues.

 

I have recently moved jobs and I now work for an organisation with approx 10K users. They use VSphere for their infrastructure so I feel it would be beneficial for me to start getting to know it a little more, and maybe looking into the certifications from VMWare,

 

On my home network I currently use Hyper-V but after some frustration today I thought that I should possibly try VMWare and go with VSphere. I do not have the best setup, I have 5 x 2TB disks for data backing up to a Synology. There is no hardware RAID or any sort of redundancy other than my Synology.

 

I do Storage Pools in HyperV though to make all of my drives appear as one larger driver just over 7TB with parity. - Does the free version of VMWare, or any version offer a similar setup to this?

 

I just want something reliable, that works, and that doesn't run like crap, which HyperV is doing at the moment, every VM I create runs slow, and I just cannot be bothered troubleshooting it when VMWare may be a better option for me.

 

Just to clarify also...

I assume VMWare is the company, VSphere is just a product. And the VSphere Client allows you to manage the product? I have used the client before and have had a basic play around with it all, but I really feel I should get more involved, what better way than to set this up on my home environment.

 

Thanks!
