This one works: $ ./x86_64-softmmu/qemu-system-x86_64 -vga cirrus -M pc-0.12
But this does not: $ ./x86_64-softmmu/qemu-system-x86_64 -vga std -M pc-0.12 qemu-system-x86_64: /build/qemu/git/memory.c:1259: memory_region_add_subregion_common: Assertion `!subregion->parent' failed. Aborted Can we fix this somehow? Thanks! /mjt
