A side effect of the second change is that you can specify just
"crashkernel=64m" and have it moved to the right place just above the
xen heap automagically.

Does this really work in practice (i.e., is the crashkernel relocatable)?

Patches floating around for quite some time, i386 is mainline already. Not fully sure about x86_64, but I think it they are merged too. So any recent mainline kernel as crash kernel should do (and a separate crash kernel isn't needed too).

Also with the default xenheap size the crashkernel ends up at @16m, which is a common location for pre-relocation crash kernels, so it should work with older kernels just fine too. Of course you still have the option to explicitly specify the location ...

cheers,
