Host Profile Customization Issue

vSphere Host Profiles is a great feature for consistent ESXi host configuration and compliance checks, but can at times be flaky.

I’ve noticed an issue recently with Host Profiles in vSphere 6.7, where after providing host customization values the following error is shown in vSphere Web Client:

The “Update host customizations” operation failed for the entity with the following error message.

Host settings validation failed.

This is how the error message looks like in the client:

Even though it’s a bit annoying, I found it to be a furphy. Customizations are actually saved successfully and the error can be ignored. You can find the following messages in ESXi host’s /var/log/syslog.log file, which confirm that it works:


INFO: Execute completed
INFO: Validating AnswerFile Status1 = success
INFO: Cleaned up Host Configuration
INFO: GetAnswerFile completed

I’ve also found that this error doesn’t appear when you provide host customization values first time straight after attaching a profile to the host. Only when you update them. It also doesn’t show up in HTML5, only Web Client. I guess, one more reason to switch to HTML5.

Hope this blog post helps someone who searched in Google, but couldn’t find any information related to this error message.
