The invention provides a method and device for importing a mirror image of a virtual machine in the cloud calculation. The method for importing the mirror image of the virtual machine in the cloud calculation comprises the following steps of: receiving the imported mirror image of the virtual machine; extracting a data signature of the mirror image of the virtual machine; decrypting the data signature to obtain a hash value of the mirror image of the virtual machine; calculating the original hash value of the mirror image of the virtual machine; and if the obtained hash value is judged to be identical to the calculated original hash value, allowing the virtual machine to be imported. The invention aims at solving the problem that the mirror image of the virtual machine is imported illegally, thereby ensuring the safety importing of the mirror image of the virtual machine.
Description
technical field [0001] The invention relates to computer network technology, in particular to a method and device for importing a virtual machine image in cloud computing. Background technique [0002] Cloud computing is an emerging method of sharing infrastructure, which can connect huge system pools together to provide various IT services. It makes possible the free flow of supercomputing power through the Internet. That is. Cloud computing is an Internet-oriented distributed computing service, which can be roughly divided into three categories according to service types: infrastructure as a service IAAS, platform as a service PAAS, and software as a service SAAS. Enterprises and individual users no longer need to invest in expensive hardware purchase costs, they only need to purchase leased computing power through the Internet, "use your computer as the access to the Internet. The network that provides resources is called "cloud". Among them, the cloud For public cloud...
