migration: Fix analyze-migration read operation signedness
The migration code uses unsigned values for 16, 32 and 64-bit operations. Fix the script to do the same. This was causing an issue when parsing the migration stream generated on the ppc64 target because one of instance_ids was larger than the 32bit signed maximum: Traceback (most recent call last): File "/home/fabiano/kvm/qemu/build/scripts/analyze-migration.py", line 658, in <module> dump.read(dump_memory = args.memory) File "/home/fabiano/kvm/qemu/build/scripts/analyze-migration.py", line 592, in read classdesc = self.section_classes[section_key] KeyError: ('spapr_iommu', -2147483648) Signed-off-by: Fabiano Rosas <farosas@suse.de> Reviewed-by: Juan Quintela <quintela@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com> Message-ID: <20231009184326.15777-6-farosas@suse.de>
