There is a similar bug with similar bt log: Bug 1048575 - Segmentation fault occurs after migrate guest(use scsi disk and add stress) to des machine The backtrace is exactly the same than 1048575, so closing this one. *** This bug has been marked as a duplicate of bug 1048575 *** Unfortunately you forgot to include the qemu output before the crash. Please
make sure to incluce it in future bug reports.
The bug that this is now marked a duplicate of mentions this output:
> qcow2: Preventing invalid write on metadata (overlaps with refcount block); image marked as corrupt.
> block I/O error in device 'scsi-disk0': Input/output error (5)
Such output is a key to understanding what's happening. I will assume that you
got the same output unless you tell us otherwise.
