摘要： Systems and methods for optimizing read operations from a storage device in a virtualized computing environment are provided. One method comprises monitoring read operations issued by an application running on a virtual machine's (VM) operating system, wherein the VM is hosted by a hypervisor providing access to a storage device in a virtualized computing environment; and causing a virtual file system (VFS) supported by the operating system to call on a first para-virtualized file system (PVFS FE) supported by the operating system to execute a read operation, in response to determining that the read operation is for reading target data from the storage device.

摘要： A method for managing memory in a nested virtualization environment is provided. The method comprises implementing a first virtual machine (VM) for a first software such that a first guest memory is allocated to the first software; maintaining a first data structure to translate one or more memory addresses in the first guest memory to corresponding memory addresses in a physical memory; maintaining a second data structure to translate one or more memory addresses in the second guest memory to corresponding memory addresses in the physical memory. The first software implements a second VM for a second software such that a second guest memory is allocated to the second software and maintains a third data structure to translate one or more memory addresses in the second guest memory to corresponding memory addresses in the first guest memory.
