VMware ESXi - Detecting incorrect OS version after open-vm-tools installation

resuni · 05-13-2017, 09:45 AM

I have a CentOS 7 guest in ESXi 6.5. I installed VMware tools using the open-vm-tools package. After I install tools and reboot, I get an error message in the vSphere web client:

Quote:

The configured guest OS (CentOS 7 (64-bit)) for this virtual machine does not match the guest that is currently running (CentOS 4/5 or later (64-bit)). You should specify the correct guest OS to allow for guest-specific optimizations.

This has happened to me on other ESXi servers as well, and I'd like to find out why. Is this just a bug? Is additional configuration required for open-vm-tools?

It's also possible I'm incorrectly correlating this with the installation of open-vm-tools. It could be that simply rebooting it caused vSphere to start detecting the wrong CentOS version.

If anyone reading this has seen similar issues with other distributions running as guests in ESXi, I would be interested to hear your experience.

If it's a shell script that starts it up, maybe you can hack it to ignore the OS version or make it compatible with whatever your OS is returning?

I have exactly the same problem. Any ideas?

I encountered the same issue after uploading a Workstation 12 VM (CentOS 64 bit) to Esxi 6.5.
To fix this issue I had to use the option Upgrade VM compatibility.
