It's pretty clear that what's happening is that qemu opening the file and the filesystem is claiming it's an empty file. So, I recommend you do the following: First: du -sh /mnt/partitions/windows0/qmeu-disk ls -al /mnt/partitions/windows0/qmeu-disk And make sure both report a non-zero result. If either reports 0 as the size, then you screwed up copying the file to your vfat partition. Second: In vl.h, change: #ifndef O_LARGEFILE #define O_LARGEFILE 0 #endif To: #ifdef O_LARGEFILE #undef O_LARGEFILE #endif #define O_LARGEFILE 0 And if that fixes your problem, then vfat is broken when open()'d with O_LARGEFILE. If that's the case, you should report it as a vfat bug.
