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
Example:
{ "event": "BLOCK_IO_ERROR",
"data": { "device": "ide0-hd1",
"operation": "write",
"action": "stop" },
"timestamp": { "seconds": 1265044230, "microseconds": 450486 } }
Note: If action is "stop", a STOP event will eventually follow the
BLOCK_IO_ERROR event.
RESET
-----
Emitted when the Virtual Machine is reseted.
Data: None.
Example:
{ "event": "RESET",
"timestamp": { "seconds": 1267041653, "microseconds": 9518 } }
RTC_CHANGE
----------
Emitted when the RTC time changes.
Data:
- "offset": delta against the host UTC in seconds (json-number)
Example:
{ "event": "RTC_CHANGE",
"data": { "offset": 78 },
"timestamp": { "seconds": 1267020223, "microseconds": 435656 } }
SHUTDOWN
--------
Emitted when the Virtual Machine is powered down.
Data: None.
Example:
{ "event": "SHUTDOWN",
"timestamp": { "seconds": 1267040730, "microseconds": 682951 } }
Note: If the command-line option "-no-shutdown" has been specified, a STOP
event will eventually follow the SHUTDOWN event.
STOP
----
Emitted when the Virtual Machine is stopped.
Data: None.
Example:
{ "event": "SHUTDOWN",
"timestamp": { "seconds": 1267041730, "microseconds": 281295 } }
VNC_CONNECTED
-------------
Emitted when a VNC client establishes a connection.
Data:
- "server": Server information (json-object)
- "host": IP address (json-string)
- "service": port number (json-string)
- "family": address family (json-string, "ipv4" or "ipv6")
- "auth": authentication method (json-string, optional)
- "client": Client information (json-object)
- "host": IP address (json-string)
- "service": port number (json-string)
- "family": address family (json-string, "ipv4" or "ipv6")
Example:
{ "event": "VNC_CONNECTED",
"data": {
"server": { "auth": "sasl", "family": "ipv4",
"service": "5901", "host": "0.0.0.0" },
"client": { "family": "ipv4", "service": "58425",
"host": "127.0.0.1" } },
"timestamp": { "seconds": 1262976601, "microseconds": 975795 } }
Note: This event is emitted before any authentication takes place, thus
the authentication ID is not provided.
VNC_DISCONNECTED
----------------
Emitted when the conection is closed.
Data:
- "server": Server information (json-object)
- "host": IP address (json-string)
- "service": port number (json-string)
- "family": address family (json-string, "ipv4" or "ipv6")
- "auth": authentication method (json-string, optional)
- "client": Client information (json-object)
- "host": IP address (json-string)
- "service": port number (json-string)
- "family": address family (json-string, "ipv4" or "ipv6")
- "x509_dname": TLS dname (json-string, optional)
- "sasl_username": SASL username (json-string, optional)
Example:
{ "event": "VNC_DISCONNECTED",
"data": {
"server": { "auth": "sasl", "family": "ipv4",
"service": "5901", "host": "0.0.0.0" },
"client": { "family": "ipv4", "service": "58425",
"host": "127.0.0.1", "sasl_username": "luiz" } },
"timestamp": { "seconds": 1262976601, "microseconds": 975795 } }
VNC_INITIALIZED
---------------
Emitted after authentication takes place (if any) and the VNC session is
made active.
Data:
- "server": Server information (json-object)
- "host": IP address (json-string)
- "service": port number (json-string)
- "family": address family (json-string, "ipv4" or "ipv6")
- "auth": authentication method (json-string, optional)
- "client": Client information (json-object)
- "host": IP address (json-string)
- "service": port number (json-string)
- "family": address family (json-string, "ipv4" or "ipv6")
- "x509_dname": TLS dname (json-string, optional)
- "sasl_username": SASL username (json-string, optional)
Example:
{ "event": "VNC_INITIALIZED",
"data": {
"server": { "auth": "sasl", "family": "ipv4",
"service": "5901", "host": "0.0.0.0"},
"client": { "family": "ipv4", "service": "46089",
