Description David Woodhouse 2009-11-07 09:05:32 EST
See 32-bit arithmetic on 'position' in the seek_to_sector() function in block/parallels.c No wonder it gives me crap. Making 'position' a uint64_t and ensuring that the arithmetic on it is also suitably cast to uint64_t gives me a more reasonable converted image.

Fix is committed upstream now http://repo.or.cz/w/qemu.git/commitdiff/c34d2451ed dwmw2: do you need cherry-picked into F-12, or are you happy to mark this as CLOSED UPSTREAM ?
Comment 2 David Woodhouse 2009-11-19 06:01:19 EST
Turns out I can't get our Parallels images (of Windows XP) to boot in qemu/KVM anyway -- I can't seem to solve the problems described at http://www.virtualbox.org/wiki/Migrate_Windows So for now I'm not advising people to convert our existing Parallels images -- if I do get it working, I'd probably have to give them a 'fixed' image, which might as well be in qcow2 format already. So I'm not personally desperate to get it, but it _would_ be nice to drop it into the next update if it's not too much trouble -- a conversion tool which can only handle images smaller than 4GiB isn't really something we should be shipping these days :)
