[libvirt] [PATCH 0/7] Update systemtap probing

When looking at the keep alive code I needed an easy way to monitor the RPC messages being sent/received. I toyed with writing a WireShark plugin, but this seemed very hard work. So instead I wrote a handy set of DTrace probes for the RPC layer At the same time I also needed to track a bug in the RPC console streams code. These probes were very convenient for diagnosing the problems there
