Oh, yes, we haven't done arm64 guests yet... Sorry I forgot about this
before. Hrm, that does rather block you from doing arm64 mini-os.

I posted a series to allow 64-bit dom0 a while back but we are currently
frozen so it has been committed, but that's the obvious starting point
for 64-bit guest support.

I don't recall why you are looking at 64-bit minios rather than 32-bit,
is that an option? A lot of the code should end up common.

Ian.
