I might be missing something obvious but ...
QEMU has a nice 'memsave' command which lets you save/dump parts of guest memory to a file. Is there a similar feature in Xen?
(Note I don't want to dump all memory to a core file, just snoop on small sections of memory).

Don't know of a tool to do that, but you can map the guest's memory using the xc_map_foreign_*() API.
Take a look at xen/tools/xentrace/xenctx.c to see how it pokes around in guest memory when dumping a stack trace.
