Abstract
Methods and systems for performing file transfers across different domains hosted by a virtualization server are described herein. A trusted domain (Dom 0) may indicate that one or more files, directories, and/or volumes are available to a second domain (guest domain) by updating share information stored in a key value store. The guest domain may enumerate the shared files to appear as if within its own file system structure. The guest domain intercepts calls to its file system, determines whether the requested data is actually stored in its own file system or in trusted domain, and proxies the file system call to the trusted domain when the requested data is shared by the trusted domain. Key value store information and shared data information and contents may be communicated using one or more memories shared between the trusted domain and guest domain.
