This paper presents Xenprobes, a lightweight framework
to probe the guest kernels of Xen Virtual Machine. Xenprobes
is useful for various purposes such as as monitoring
real-time status of production systems, analyzing
performance bottlenecks, logging specific events or tracing
problems of Xen-based guest kernel. Compared to
other kernel probe solutions, Xenprobes introduces some
unique advantages. To name a few: First, our framework
puts the the breakpoint handlers in user-space, so it is
significantly easier to develop and debug. Second, Xenprobes
allows to probe multiple guests at the same time.
Last but not least, Xenprobes supports all kind of Operating
Systems supported by Xen.
