Re: [Xen-devel] gdbserver-xen frustration on x86_64

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

If a bug crashes Xen then the printed backtrace is almost always sufficient.
Kdump can also be useful if we want to post-mortem analyse the heap. For
more subtle bugs, we almost always look to find a workload that reliably
repros the issue, and then we add custom tracing to Xen to narrow down the
possibilities. This latter kind of bug is not really amenable to debugging
with a traditional debugger.
