Hi Behrad,
   you'll need newer ESXi version (7.0), and virtual machine using 
hardware version 17 to have vmxnet3 device that supports more than 8 queues.

Then you'll need newer guest driver to be able to use the feature - 
currently driver in the Linux kernel does not support extended queues.

Hi,

After upgrading glib from 2.61.0 to 2.63.4, I am getting Deprecation error
for open-vm-tools 11.0.5-15389592 as below :

How to generate a reliable UUID inside a guest image?

[Karl M. <kme...@me...>]

I was hoping to ask for some design help on VMWare.

I am developing a new licensing feature for a desktop app.


A typical solution to this problem is a stand-alone license server which 
just counts concurrent licensed instances on the LAN.    Unfortunately, 
the customer has taken that offtheytable and require us to do software 
only, disconnected, per seat activation.   I know their environment and 
their reasons are mission critical for them...

So to implement the license policy requires us to uniquely identify each 
physical machine the app is installed with a UUID.   For the case of 
Windows running hardware, we can make a hash value from the serial 
numbers in the bios through WMI and treat the hash value as a UUID.    
Although there is a risk a determined cheat could spoof their bios we 
decided that was an acceptable risk since bios spoofing is clumsy.   
Above a certain level of effort they could just edit our assembly and 
crack the security check anyway...


The case of Windows in a guest OS on VMWare is harder to design 
something robust to very simple cheating.   Just about everything in the 
guest OS is configurable and easily replicated with thevmxand 
checkpointing. So guest OS features like the bios or MAC addresses just 
seem too easy for a user to spoof by making many instances of particular 
(licensed) guest image.

I am looking for something an application can query which identifies the 
underlying host in a robust way.

One solution I been exploring is using theVMXhIO port to query the 
underlying host.    Using the IO Port was very attractive since it 
seemed to require minimal dependencies, installation and configuring  
and was typically on by default

According to
https://sites.google.com/site/chitchatvmback/backdoor#cmd0fh

command 13h will provide the bios UUID but then I realized that VMWare 
allows multiple instances of a particular guest image as long as they 
run on physically distinct hosts.  It seems I really need to be asking 
for the/HOST's/UUID

The PowerCLI does seem to provide that data with the Get-VMHost command

https://www.vmware.com/support/developer/PowerCLI/PowerCLI41U1/html/Get-VMHost.html

something like

(Get-VMHost -Name MY_VCENTER_IP).ExtensionData.hardware.systeminfo.uuid

Is therea IOPort way to get the same or equivalent value - the physical 
host UUID?

  I just need a stable and robust way to identify what (physical) 
machine the app is running on.   Ideally, one which is simple to 
implement and does not have a lot of dependencies or configuration for 
the customer to deal with.


thanks
Karl Meissner

Want to edit source to add specific options for vmtoolsd.service file

[Achilles G. <ach...@gm...>]

Hello!

I am looking for the file that is creating the following service file :

~~~
/usr/lib/systemd/system/vmtoolsd.service
~~~

My aim is to simply add extra arguments and make specific changes in
Exec section
of the aforementioned service file.

something like :

~~~
-ExecStart = /usr/bin/vmtoolsd
+ExecStart = /usr/bin/vmtoolsd  ARG1 ARG2
~~~

I know I can edit the unit file simply, but I want to build a binary
which would have this by default for some of my systems.

The above is just an example, I wish to execute vmtoolsd in a different
namespace than it currently runs in.


Best,
Achilles

Use VMWare's own VMware Tools, or native open-vm-tools with RHEL/CentOS 6.x guest OS?

[spezialist <spe...@em...>]

Hi all!
 
In continuation of the topic, published on https://communities.vmware.com/message/2721551#2721551: what is VMware Co. thinks that open-vm-tools have long been available as ready-made rpm-files for RHEL/CentOS 6.x on EPEL repo?
 
I.e., can I use the RHEL/CentOS 6.x guest OS with the above rpm-files from EPEL repo, for example under ESXi 5.5U3? Problems will be or not?

And the most important question -- is whether VMware Co will refuse me in the official technical support if on the RHEL/CentOS 6.x guest OS I will have open-vm-tools installed from the EPEL repository, rather than native vmware-tools.
 
Very thanks for the support.

Re: Time not syncing after VMotion

[Ravindra K. <rav...@vm...>]

You might have missed the second part of the documentation, which talks about the option "pref.timeLagInMilliseconds". One time sync does not kick in if the error is within 1000 milliseconds. This threshold can be controlled using "pref.timeLagInMilliseconds". Could you please check this?

So every time we do a VMotion, our guest clock is off by a few hundred milliseconds. We do run ntpd, so it eventually corrects itself. But these time discrepancies can cause problems until ntpd gets around to fixing things. According to various resources I can find on the internet, the time is supposed to be synchronized after a few events happen, such as snapshots, and vmotions.
We have the periodic time sync disabled (though we tried with it enabled, and it made no difference). We do not have any of the "time.synchronize.*" options set in the vmx file.

Any idea why the time is not synchronizing? Or how to debug this?

Hi Cedric,
    you do not need any Tools at all for CPU & memory hot-add to work.

What VMware Tools (both bundled and open) do is that they attempt to 
configure system for you: they make sure that acpi_memhotplug is loaded, 
and provides script that tries to bring hot-added resources online 
automatically.

Current distributions usually take care of both of these tasks 
automatically, as part of their systemd & udev setup, and so you do not 
need any VMware Tools involvement to get this functionality (f.e. 
Windows always supported this functionality without Tools present)

auto resize down of desktop not working

I upgraded this from 15.04 to 15.10 and everything worked just fine.

Upgraded to 16.04 and resize works just fine as long as I am going to a
larger screen size or expanding to the second monitor with the "Cycle
Multiple Monitors" button on VMware Workstation.

Changing the size of the VMware Workstation window, turning off full
screen mode, or going back to a single monitor does not cause an
automatic resize down.  The scroll bars on the VMware Workstation
appear.  I can scroll just fine, but the mouse location is no longer in
sync with what is displayed on the screen.

open-vm-tools manually start

[PRISCO F. <pri...@gm...>]

Hi guys,
 I am looking to the open-vm-tools compiling phase.

I did not finished the correct procedure, I mean if I don't want to "make
install" at the end of the compilation, how can I start the vmtoolsd
"manually"?

By looking to my Virtual Machine I can see:

root@ubuntuvm:~# ps -ef | grep vmtoolsd
root      1802     1  0 15:13 ?        00:00:00 */usr/sbin/vmtoolsd*

*/usr/lib/vmware-tools/sbin32/vmtoolsd
-n vmusr --blockFd 3*

Is not clear for me if I have to lunch vmtoolsd binary file by passing the
previous parameters.
I am asking because I am using this VM just to build, I need to lunch the
executable file on another machine.

I have opened another post regarding hearbeat feature.
I need the heartbeat functionality to check if from my host vsphere machine
(for some reason) my VM is locked, I hope that HA feature will restart it
in case VM doesn't answer to some events.


Could you help me to find "open-vm-tools" documentation?
