BLOCK_IO_ERROR events are logged by libvirt, which helps with post mortem analysis of guests. However, one information that we miss today is a human readable string describing the cause of the I/O error. This commit adds that string it to BLOCK_IO_ERROR. Note that this string is a debugging aid for humans, meaning that it should not parsed by applications.
