You can create custom attributes in the vSphere Client and associate the attribute with an object, such as a host, virtual machine, cluster, or network. You can also edit custom attributes.
After you create the attributes, set an appropriate value for the attribute on each virtual machine. This value is stored with vCenter Server and not with the virtual machine. Use the new attribute to filter your virtual machines. If you no longer need the custom attribute, remove it. A custom attribute is always a string.
Note: Tags and tag categories support a finer-grained mechanism for tagging your object. Consider using tags and tag categories instead of custom attributes.
