This patchset provides the infrastructure for supporting dynamic probing of libvirtd, using static DTrace markers. This can be used by SystemTAP on Linux, or DTrace on Solaris/OS-X/BSD for low overhead tracing.
The proof of concept provides a handful of markers wrt to network client connections, security & auth. Obviously it can be expanded to cover a huge area of our codebase for different tasks. The hard bit is deciding what should be exposed as a probe point. Ideally probes should not be changed/removed once added, since this would break any user tracing scripts. So a little care needs to be taken in placing probes to be robust against future code re-factoring.
