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. Cheers, Andre
