@item cache-size
The maximum total size of the L2 table and refcount block caches in bytes
-(default: 1048576 bytes or 8 clusters, whichever is larger)
+(default: the sum of l2-cache-size and refcount-cache-size)
@item l2-cache-size
The maximum size of the L2 table cache in bytes
-(default: 4/5 of the total cache size)
+(default: if cache-size is not specified - 32M on Linux platforms, and 8M on
+non-Linux platforms; otherwise, as large as possible within the cache-size,
+while permitting the requested or the minimal refcount cache size)
@item refcount-cache-size
The maximum size of the refcount block cache in bytes
-(default: 1/5 of the total cache size)
+(default: 4 times the cluster size; or if cache-size is specified, the part of
+it which is not used for the L2 cache)
@item cache-clean-interval
Clean unused entries in the L2 and refcount caches. The interval is in seconds.
-The default value is 0 and it disables this feature.
+The default value is 600 on supporting platforms, and 0 on other platforms.
+Setting it to 0 disables this feature.
@item pass-discard-request
Whether discard requests to the qcow2 device should be forwarded to the data
mechanism. The credentials should have been previously created
using the @option{-object tls-creds} argument.
-The @option{tls-creds} parameter obsoletes the @option{tls},
-@option{x509}, and @option{x509verify} options, and as such
-it is not permitted to set both new and old type options at
-the same time.
-
-@item tls
-
-Require that client use TLS when communicating with the VNC server. This
-uses anonymous TLS credentials so is susceptible to a man-in-the-middle
-attack. It is recommended that this option be combined with either the
-@option{x509} or @option{x509verify} options.
-
-This option is now deprecated in favor of using the @option{tls-creds}
-argument.
-
-@item x509=@var{/path/to/certificate/dir}
-
-Valid if @option{tls} is specified. Require that x509 credentials are used
-for negotiating the TLS session. The server will send its x509 certificate
-to the client. It is recommended that a password be set on the VNC server
-to provide authentication of the client when this is used. The path following
-this option specifies where the x509 certificates are to be loaded from.
-See the @ref{vnc_security} section for details on generating certificates.
-
-This option is now deprecated in favour of using the @option{tls-creds}
-argument.
-
-@item x509verify=@var{/path/to/certificate/dir}
-
-Valid if @option{tls} is specified. Require that x509 credentials are used
-for negotiating the TLS session. The server will send its x509 certificate
-to the client, and request that the client send its own x509 certificate.
-The server will validate the client's certificate against the CA certificate,
-and reject clients when validation fails. If the certificate authority is
-trusted, this is a sufficient authentication mechanism. You may still wish
-to set a password on the VNC server as a second authentication layer. The
-path following this option specifies where the x509 certificates are to
-be loaded from. See the @ref{vnc_security} section for details on generating
-certificates.

-This option is now deprecated in favour of using the @option{tls-creds}
-argument.
