Sounds interesting.

What I was actually trying (not successfully yet) was to see if I
could make a fake binary which just contains debug info for the few
kernel structures I care about.  Starting with task_struct as an
example.  Then it should be a simple matter of loading those symbols
using 'symbol-file'.

These "fake binaries" should be quite a lot smaller than an entire
vmlinux.

As I said I haven't actually made this work yet.

Also working on a virDomainMemoryPeek patch for crash.
