This is normal, we are creating a small device-tree to pass some
information to dom0 (such as the ACPI tables, command line, initrd).

I didn't go very far during my testing because QEMU is providing ACPI
5.1 (Xen only supports 6.0+ so far).
For your log above, Xen finished to boot and now dom0 should start
booting. The lack of console output may be because of a crash in Linux
during earlyboot.
Do you have the early console enabled Linux? This can be done by adding
earlycon=xenboot on the Linux command line.
