|  | QEMU Monitor Protocol Events | 
|  | ============================ | 
|  |  | 
|  | BLOCK_IO_ERROR | 
|  | -------------- | 
|  |  | 
|  | Emitted when a disk I/O error occurs. | 
|  |  | 
|  | Data: | 
|  |  | 
|  | - "device": device name (json-string) | 
|  | - "operation": I/O operation (json-string, "read" or "write") | 
|  | - "action": action that has been taken, it's one of the following (json-string): | 
|  | "ignore": error has been ignored | 
|  | "report": error has been reported to the device | 
|  | "stop": error caused VM to be stopped |
