Abnormality handling method and system, agency device and control device

The embodiment of the invention provides abnormality handling method and system, an agency device and a control device. The method comprises the steps of monitoring whether abnormality occurs in a monitored object through the agency device of a physical machine, wherein the monitored object is a virtual machine which runs in the physical machine, or an application or an application set of the virtual machine running in the physical machine; sending information about the abnormality of the monitored object to the control device through the agency device of the physical machine in case of abnormality occurs in the monitored object, so as to update the state information of the monitored object stored by the control device into abnormal state information through the control device; receiving a configuration strategy message from the control device, wherein the configuration strategy message is configured by the control device according to the state information of the monitored object; handling the abnormality according to the configuration strategy message. With the adoption of the abnormality handling scheme for achieving HA of the virtual machine, the flexibility is relatively high.
