+\section{Error Handling}
+When a low-level transport error occurs, or a request is malformed at the HTTP
+or XML-RPC level, the server may send an XML-RPC Fault response, or the client
+may simulate the same. The client must be prepared to handle these errors,
+though they may be treated as fatal. On the wire, these are transmitted in a
+form similar to this:
+
+\begin{verbatim}
+ <methodResponse>
+ <fault>
+ <value>
+ <struct>
+ <member>
+ <name>faultCode</name>
+ <value><int>-1</int></value>
+ </member>
+ <member>
+ <name>faultString</name>
+ <value><string>Malformed request</string></value>
+ </member>
+ </struct>
+ </value>
+ </fault>
+ </methodResponse>
+\end{verbatim}
+
+All other failures are reported with a more structured error response, to
+allow better automatic response to failures, proper internationalisation of
+any error message, and easier debugging. On the wire, these are transmitted
+like this:
+
+\begin{verbatim}
+ <struct>
+ <member>
+ <name>Status</name>
+ <value>Failure</value>
+ </member>
+ <member>
+ <name>ErrorDescription</name>
+ <value>
+ <array>
+ <data>
+ <value>MAP_DUPLICATE_KEY</value>
+ <value>Customer</value>
+ <value>eSpeil Inc.</value>
+ <value>eSpeil Incorporated</value>
+ </data>
+ </array>
+ </value>
+ </member>
+ </struct>
+\end{verbatim}
+
+Note that {\tt ErrorDescription} value is an array of string values. The
+first element of the array is an error code; the remainder of the array are
+strings representing error parameters relating to that code. In this case,
+the client has attempted to add the mapping {\tt Customer $\rightarrow$
+eSpiel Incorporated} to a Map, but it already contains the mapping
+{\tt Customer $\rightarrow$ eSpiel Inc.}, and so the request has failed.
+
+The reference below lists each possible error returned by each method.
+As well as the errors explicitly listed, any method may return low-level
+errors as described above, or any of the following generic errors:
+
+\begin{itemize}
+\item HANDLE\_INVALID
+\item INTERNAL\_ERROR
+\item MAP\_DUPLICATE\_KEY
+\item MESSAGE\_METHOD\_UNKNOWN
+\item MESSAGE\_PARAMETER\_COUNT\_MISMATCH
+\item OPERATION\_NOT\_ALLOWED
+\item PERMISSION\_DENIED
+\item SESSION\_INVALID
+\end{itemize}
+
+Each possible error code is documented in the following section.
+
+\subsection{Error Codes}
+
+\subsubsection{HANDLE\_INVALID}
+
+You gave an invalid handle. The object may have recently been deleted.
+The class parameter gives the type of reference given, and the handle
+parameter echoes the bad value given.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}HANDLE_INVALID(class, handle)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{INTERNAL\_ERROR}
+
+The server failed to handle your request, due to an internal error. The
+given message may give details useful for debugging the problem.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}INTERNAL_ERROR(message)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{MAP\_DUPLICATE\_KEY}
+
+You tried to add a key-value pair to a map, but that key is already there.
+The key, current value, and the new value that you tried to set are all
+echoed.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}MAP_DUPLICATE_KEY(key, current value, new value)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{MESSAGE\_METHOD\_UNKNOWN}
+
+You tried to call a method that does not exist. The method name that you
+used is echoed.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}MESSAGE_METHOD_UNKNOWN(method)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{MESSAGE\_PARAMETER\_COUNT\_MISMATCH}
+
+You tried to call a method with the incorrect number of parameters. The
+fully-qualified method name that you used, and the number of received and
+expected parameters are returned.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}MESSAGE_PARAMETER_COUNT_MISMATCH(method, expected,
received)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{NETWORK\_ALREADY\_CONNECTED}
+
+You tried to create a PIF, but the network you tried to attach it to is
+already attached to some other PIF, and so the creation failed.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}NETWORK_ALREADY_CONNECTED(network, connected PIF)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}

+\subsubsection{OPERATION\_NOT\_ALLOWED}
+
+You attempted an operation that was not allowed.
+
+\vspace{0.3cm}
+No parameters.
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{PERMISSION\_DENIED}
+
+You do not have the required permissions to perform the operation.
+
+\vspace{0.3cm}
+No parameters.
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{PIF\_IS\_PHYSICAL}
+
+You tried to destroy a PIF, but it represents an aspect of the physical
+host configuration, and so cannot be destroyed. The parameter echoes the
+PIF handle you gave.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}PIF_IS_PHYSICAL(PIF)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{SESSION\_AUTHENTICATION\_FAILED}
+
+The credentials given by the user are incorrect, so access has been denied,
+and you have not been issued a session handle.
+
+\vspace{0.3cm}
+No parameters.
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{SESSION\_INVALID}
+
+You gave an invalid session handle. It may have been invalidated by a
+server restart, or timed out. You should get a new session handle, using
+one of the session.login\_ calls. This error does not invalidate the
+current connection. The handle parameter echoes the bad value given.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}SESSION_INVALID(handle)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{SESSION\_NOT\_REGISTERED}
+
+This session is not registered to receive events. You must call
+event.register before event.next. The session handle you are using is
+echoed.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}SESSION_NOT_REGISTERED(handle)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{VALUE\_NOT\_SUPPORTED}
+
+You attempted to set a value that is not supported by this implementation.
+The fully-qualified field name and the value that you tried to set are
+returned. Also returned is a developer-only diagnostic reason.
+
+\vspace{0.3cm}
+{\bf Signature:}
+\begin{verbatim}VALUE_NOT_SUPPORTED(field, value, reason)\end{verbatim}
+\begin{center}\rule{10em}{0.1pt}\end{center}
+
+\subsubsection{VLAN\_TAG\_INVALID}
+
+You tried to create a VLAN, but the tag you gave was invalid -- it mmust be
+between 0 and 4095. The parameter echoes the VLAN tag you gave.

+\subsubsection{VM\_BAD\_POWER\_STATE}
+
+You attempted an operation on a VM that was not in an appropriate power
+state at the time; for example, you attempted to start a VM that was
+already running. The parameters returned are the VM's handle, and the
+expected and actual VM state at the time of the call.
