# The following Conflicts prevents the "vswitch" package generated by

# contain some files with identical names anyhow, so they will not
# coexist, but adding an explicit Conflicts makes this conflict more

%description
The vswitch provides standard network bridging functions augmented with
support for the OpenFlow protocol for remote per-flow control of
traffic.

The original XenServer scripts replaced by this package are not those
of any supported version of XenServer.  This could lead to unexpected
behavior of your server.  Unless you are sure you know what you are
doing, it is highly recommended that you remove this package
immediately after the install completes, which will restore the
XenServer scripts that you were previously using.
