Abstract


With the popularity of virtualization technology, how to effectively monitor multiple physical computing nodes and the deployment of these physical compute nodes in the hundreds or thousands of virtual machines is a virtual machine management difficult. Currently, there are many powerful virtual machine management software, but these virtual machine management software can only get from a virtual machine virtual machine outside the basic system information and the virtual machine simple operation, especially when successful cluster environment hundreds or thousands of virtual machines running simultaneously, it is difficult to efficiently manage large-scale administrator of the virtual machine. To solve the above problems, the use of virtual machine proxy service mechanism inside the virtual machine can be obtained detailed data on the operation of the virtual machine and fine-grained control. Agency services mechanisms underlying idea is: through registered agent inside the virtual machine service module, the proxy service as a physical and virtual machines data exchange between the bridge, making the physical machine to obtain a variety of data within virtual machines and virtual machine send operation commands to achieve internal monitoring and management of virtual machines. Automatic configuration of distributed service environment to complete the virtual machine starts automatically proxy service runtime environment to build, as a service platform to provide a basis for rapid deployment. Rapid deployment of services based on incremental able to quickly establish the basis for data transmission service module. The use of virtual machine data acquisition and persistence internal model can be run inside the virtual machine status in real-time monitoring and data persistence saved. Advanced Control virtual machine virtual machine model enables batch operations, improve administrator productivity. Error detection and recovery mechanisms to ensure the stability of the service is running, making agency services in case of an error can be achieved automatically restored. When the proxy service interface changes need to update the service data, the automatic upgrade mechanism to ensure the virtual machine in the machine reboot or restart the service automatically when the update service data. Agency services through the pipeline scheduling algorithm and writable working set fast update algorithm ensures that minimize the amount of data transferred, optimize network bandwidth and improve transmission performance. Function tests showed: a virtual machine proxy service to shield the heterogeneity of the underlying operating system, the upper functional interface to provide a unified service, including: resource monitoring, process monitoring, disk monitoring, network monitoring, security surveillance. Performance tests show that: writable working set update algorithm to obtain the minimum amount of data update operations complete information sets the amount of data reduction 75%; adoption agency service mechanism, the virtual machine for batch operation time overhead reduction relative to VMware-tools 80%.
