I was playing around with vSphere ESXi 4.0 and the Update Manager. As Jason Boche already reported several patches have been released and I wanted to test Update Manager. After downloading all the patches I noticed that there was a patch regarding the Cisco Nexus 1000v.
Although I did not have the 1000v installed Update Manager did want to install the patch. Kind of weird because why install the patch when you are not using the plugin? I decided to exclude it from my baseline to make sure I did not install it.
I was lucky to notice it because according to this KB article it can and probably will cause issues. If you did install it read the KB article on how to remove the patch!
Now this made me rethink my patching strategy. Normally I just install every single patch out there to make sure I am running the latest and greatest version, but apparently this is not the best practice anymore. My recommendation: review your patches and if it doesn’t apply to you exclude them!
