    摘要: Tools and techniques for migrating applications to compute clouds are described herein. A tool may be used to migrate any arbitrary application to a specific implementation of a compute cloud. The tool may use a library of migration rules, apply the rules to a selected application, and in the process generate migration output. The migration output may be advisory information, revised code, patches, or the like. There may be different sets of rules for different cloud compute platforms, allowing the application to be migrated to different clouds. The rules may describe a wide range of application features and corresponding corrective actions for migrating the application. Rules may specify semantic behavior of the application, code or calls, storage, database instances, interactions with databases, operating systems hosting the application, and others.

    摘要: A logical communication path is provided between a target virtual machine (VM) and a host or application communicating with the VM. The target VM runs on a hypervisor host that has a hypervisor and a proxy agent. The hypervisor manages execution of the VM. A mapping is maintained indicating which VMs execute on which hosts. When the host or application is to send a message or packet to the target VM, the mapping is consulted and the hypervisor host hosting the target VM is identified. The message or packet, which may identify the target VM, is transmitted to the hypervisor host. A proxy agent at the hypervisor host selects a communication channel between the hypervisor and the target VM. The hypervisor then passes the message or packet through the selected channel to the target VM.

    摘要: Techniques are described for composing virtual machine images, generating signatures thereof, and verifying virtual machine images. A virtual machine image may be generated by installing or inserting software to a base virtual machine image. A signature may be computed using hash values of blocks of the base virtual machine image; blocks of the base image that are unchanged need not be hashed to generate the signature. A copy of the new virtual machine image can be verified at a computer hosting virtual machines by computing hashes only for modified or new blocks (relative to the base image). Block verification can take place in the background when a virtual machine starts; all of the blocks are verified (hashed and compared) in some order, and at the same time, unverified blocks are verified on demand as needed by the virtual machine.
