The invention discloses a virtual machine software installing method, an installing controller and an installing agent. The virtual machine software installing method comprises the steps of: after a virtual machine software installing requires which carries a target virtual machine identification is received, transmitting a disc loading request which carries the target virtual machine identification to a cloud management server so that the cloud management server loads the disc of the target virtual machine into the installing agent; transmitting the virtual machine software installing request which carries the target virtual machine identification to the installing agent, so that the installing agent generates a downloading request for replying after the virtual machine software installing request is received; and after the downloading request is received, transmitting a prestored software installing package and configuration files to the installing agent so that the installing agent writes the software installing package, the configuration files and installing tools which are prestored in the installing agent into the disc of the target virtual machine, and furthermore the target virtual machine is set to perform self-starting on the installing tools. The virtual machine software installing method, the installing controller and the installing agent settle a problem that an offline virtual machine is not supported in prior art.

The present invention provides EJB cluster failure recovery processing method, comprising the steps that: a stub of an EJB service interface is loaded in a client; the stub sends an invocation requestto a target server according to the address of the target server; the target server analyzes the invocation request, and if the invocation request relates to the invocation of stateful session bean and the target server is positioned in an EJB cluster, the session state data and session ID are extracted; the context of a current service component instance is acquired according to the session ID,and the cache of the target server is updated; a server end pile of the EJB service interface is loaded; the service component instance is updated according to the session state data; the server end pile processes the service component instance so as to generate a return value of service logic and an updating value of the session state data; the client receives the return value and the updating value to update the cache of the client. The processing method can save cost, reduce resource occupation and improve EJB cluster failure recovery processing efficiency.

The invention discloses a system and a method for providing SaaS (Security as a Service) in a cloud operating system. The system comprises a security resource pool used for centralizing security resources for pooling and providing security service for a virtual machine; an updating node used for linking to a security updating library and updating resources in the security resource pool; and a security terminal agent used for deploying a security agent program in the virtual machine and carrying out safety protection on the virtual machine through interacting with the security resource pool. According to the system and the method, the operation and maintenance efficiency of a cloud data center is improved and the operation and maintenance cost is reduced. A comprehensive and timely security protection is provided for the virtual machine in the cloud operating system, and the network storm of a computational node, which is caused by updating of security features under the conventional security protection mode, is avoided.
