qemu-2.0 -M pc-2.0
migrate to disk/s3/s4
upgrade qemu
qemu-2.2 -M pc-2.0
try interesting variation of s3/s4/migration to disk. Migration to disk
should work (we migrate BIOS ROM blocks, enphasis on ROM), s3 perhaps
(machine needs to be saved to disk), s4 ..... depends how it ends being
done.
Later, Juan.
