Description
Technical field
The present invention relates to virtual machine technique fields, and in particular to a kind of acquisition methods and system of magnetic disk of virtual machine data.
Background technique
Cloud computing system provides a kind of solution for saving operation cost of user, and user is without spending great amount of cost to buy
Hardware, as long as can reach the operation purpose of more physical machines by the application of virtual machine.
Cloud computing system includes: cloud terminal, host and cloud management server, wherein and cloud terminal can be network computer,
Such as desktop computer, laptop, tablet computer；Host can for network side for cloud terminal provide memory space, software and its
The server of his computer function can dispose multiple virtual machines on host；Cloud management server can be the clothes of network side
Business device provides the service such as user management, key management.Host and cloud management server are also referred to as cloud platform.User passes through cloud
Terminal remote, which logs in cloud platform, then can be used the function of the virtual machine on host after the identity of user is by certification.
In cloud computing environment, due to being usually deployed multiple virtual machines on host, and the operation of virtual machine be it is relatively independent,
So cloud management server wants are it is to be understood which perdurable data each virtual machine internal has, i.e., the power-off stored in virtual machine is not lost
The data of mistake, the mode for being typically employed in installation agent in virtual machine obtain, and which can accomplish to monitor in real time, but the party
Formula has the disadvantage in that
1, user's unaware is not accomplished, since agency is mounted in virtual machine, user can see from virtual machine certainly
Broker program realizes the presence of broker program conscientiously.
2, virtual machine necessarily is in open state, and be referred to as switched on state, for the state virtual machine that shuts down, i.e., in off-mode
Virtual machine, agency are unable to run, and cloud management server naturally also just can not be to broker program transmitting order to lower levels.
3, the network between virtual machine and cloud management server must be logical, if network is obstructed, cloud management server
It can not be communicated with agency, broker program performs practically no function.
4, broker program cannot be deleted and necessary normal operation, the requirement to broker program are relatively high, it is necessary to assure just
Often operation could complete sequence of operations by broker program.
5, virtual machine performance is influenced, the operation of broker program certainly will occupy a part of CPU, memory source.
