Just a quick question - will there be any support for enabling booting into virtualisation mode to run xen and the like?

This is a firmware issue. The SoC itself provides everything you need
and even Allwinner choosing ARM Trusted Firmware (ATF) to do PSCI
handling shows how to do it - but for whatever reason they hacked it to
_not_ enter the kernel (or Xen, for that matter) in EL2.

But this should be fixable - either by using U-Boot's PSCI support or by
doing a proper ATF port. I am tempted to look at the latter.

Rest assured that using KVM was the primary reason I backed the Pine64,
so this definitely will be supported some day. Booting Xen does not make
much difference in this respect then.
