    摘要: A virtual machine comprises a unique identifier that is associated with one or more encryption keys. A management server encrypts the virtual machine's virtual hard disk(s) using the one or more associated encryption keys. The management server further provides the one or more encryption keys to a limited number of one or more servers in a system. Only those one or more servers that have been provided the one or more encryption keys can be used to load, access, and/or operate the virtual machine. The management server can thus differentiate which virtual machines can be operated on which servers by differentiating which servers can receive which encryption keys. In one implementation, a management server encrypts all virtual machines in the system, but encrypts virtual machines with sensitive data with a limited set of encryption keys, and further provides those encryption keys to a limited set of trusted servers.

    摘要: Architecture that facilitates the virtual specification of a connection between physical endpoints. A network can be defined as an abstract connectivity model expressed in terms of the connectivity intent, rather than any specific technology. The connectivity model is translated into configuration settings, policies, firewall rules, etc., to implement the connectivity intent based on available physical networks and devices capabilities. The connectivity model defines the connectivity semantics of the network and controls the communication between the physical nodes in the physical network. The resultant virtual network may be a virtual overlay that is independent of the physical layer. Alternatively, the virtual overlay can also include elements and abstracts of the physical network(s). Moreover, automatic network security rules (e.g., Internet Protocol security-IPSec) can be derived from the connectivity model of the network.
