Hi Paolo,
we have been trying to fix a BSOD that would happen during the Windows
XP installation, once every ten times on average.
After many days of bisection, we found out that commit
commit 149f54b53b7666a3facd45e86eece60ce7d3b114
Author: Paolo Bonzini <address@hidden>

memory: add address_space_translate
breaks Xen support in QEMU, in particular the Xen mapcache.
The reason is that after this commit, l in address_space_rw can span a
page boundary, however qemu_get_ram_ptr still calls xen_map_cache asking
to map a single page (if block->offset == 0).
The appended patch works around the issue by reverting to the old
behaviour.
What do you think is the right fix for this?
Maybe we need to add a size parameter to qemu_get_ram_ptr?
