Hello,
Since #18932 hasn't been approved, there's no reliable way to avoid ESX inventory override the inventory of VMs made with GLPI-Agent installed locally. I use ESX inventory because some machines do not allow the GLPI-Agent be installed locally. The only way to filter those machines is using the "Model" field, since ESX inventory do not provide them, but GLPI-Agent does, so I created the following filter rules:

It denies the importing of assets with no "Model" field is already present but is missing on inventory data, but that wasn't working as expected and the local GLPI-Agent data was being overriden by ESX inventory anyway. It happens because GLPI only validates the rules when adding a VM (as can be seen on the same file edited on this commit), but not for update. Now it also checks the rules when updating the Computer asset, and only updates it if rules allows it, thus avoiding the override.
