+Custom CPU Types
+^^^^^^^^^^^^^^^^
+
+You can specify custom CPU types with a configurable set of features. These are
+maintained in the configuration file `/etc/pve/virtual-guest/cpu-models.conf` by
+an administrator. See `man cpu-models.conf` for format details.
+
+Specified custom types can be selected by any user with the `Sys.Audit`
+privilege on `/nodes`. When configuring a custom CPU type for a VM via the CLI
+or API, the name needs to be prefixed with 'custom-'.
