Are you sure this branch is functional?

I strongly recommend that you stick to the well known trees referenced
from
http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Allwinner

If you want to use some other tree then the onus is on you to ensure
that it is functional on baremetal before running it under Xen.

Does the SD card work when the kernel is booted baremetal/natively
without Xen?
