It's a production mail server which was affected, and it's being used at the moment. Not sure if I can narrow it down that easily :-) > Do I understand correctly that your image fails with the kvm-73 version > of block-qcow2.c and afterwards boots with kvm-72?

That's correct, it's always booted when trying again with kvm-72, or a later kvm with block-qcow2.c reverted. It might be an I/O error rather than corruption. Up to kvm-76, I/O errors aren't reported over the IDE driver. -- Jamie -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
