Daniel P. Berrangé e937929c16 wireshark: drop gmodule.h include to avoid glib warnings
The wireshark address.h header uses 'g_memdup2' but this triggers
warnings under clang due to the max version cap:

It is unclear why clang warns, but gcc does not. Our plugin doesn't
actually use the inline helper in address.h that references g_memdup2,
but we get the warning regardless.

Interestingly removing the 'gmodule.h' include avoids the warning. Since
there is nothing in plugin.c that appears to need gmodule.h, removing it
should be safe & done regardless.

About

This is the project of Google Summer of Code 2013 accepted by QEMU.org and libvirt community. The goal of this project is, provide Wireshark dissector for Libvirt RPC protocol. It will provide Libvirt packet overview/detail analysing in Wireshark. Furthermore, it will be able to build(generated) from RPC protocol definition placed in Libvirt source tree to support latest protocol specification.

See also:

Installation

Run ./configure with --with-wireshark-dissector option enabled. Then dissector will compiled with libvirt itself.

Add/Remove protocol from dissector's support

Modify argument input in tools/wireshark/src/libvirt/meson.build.

Changing installation directory

You can change installation directory of pluggable shared object(libvirt.so) by specifying --with-ws-plugindir=<path>.

You can install libvirt.so into your local wireshark plugin directory:

$ ./configure --with-wireshark-dissector \
              --with-ws-plugindir=$HOME/.wireshark/plugins
