Re: [Xen-devel] gdbserver-xen frustration on x86_64
I'm afraid the simple answer is that gdbserver-xen spends a lot of the time
broken in one way or another because none of the core developers use it or
test it. In this case it looks like guest memory can't be accessed for some
reason -- do you get similar messages if you try to use
tools/xentrace/xenctx binary on this VM? It looks like it might not be too
hard to fix this particular issue, since it's rather un-subtle. :-)
