摘要： A method for automatically modifying an executable file for a software agent is provided. The method comprises detecting original static entry and exit points in the executable file and generating corresponding transformed points; modifying the executable file by linking the executable file to the integrity services environment and embedding a signed agent manifest; loading the modified executable file into memory and registering a target list with the software agent's hypervisor, wherein the target list provides mappings between protected and active page tables; detecting dynamic entry and exit points in the executable file and generating corresponding transformed points; switching to a protected context, in response to a transformed exit point being invoked, and switching to an active context, in response a transformed entry point being invoked; and de-registering the software agent with the memory protection module, in response to the software agent being unloaded.

摘要： Methods and apparatus relating to processor extensions for execution of secure embedded containers are described. In an embodiment, a scalable solution for manageability function is provided, e.g., for UMPC environments or otherwise where utilizing a dedicated processor or microcontroller for manageability is inappropriate or impractical. For example, in an embodiment, an OS (Operating System) or VMM (Virtual Machine Manager) Independent (generally referred to herein as “OI”) architecture involves creating one or more containers on a processor by dynamically partitioning resources (such as processor cycles, memory, devices) between the HOST OS/VMM and the OI container. Other embodiments are also described and claimed.

摘要： A system and method are disclosed. In one embodiment the system includes a physical resource that is capable of generating I/O data. The system also includes multiple virtual machines to utilize the physical resource. Among the virtual machines are a resource source virtual machine that is capable of owning the physical resource. The resource source virtual machine is also capable of sending a stream of one or more I/O packets generated from the I/O data that targets a resource sink virtual machine. The resource sink virtual machine is designated as a termination endpoint of the I/O data from the physical device. Also among the virtual machines are one or more resource filter virtual machines. Each of the resource filter virtual machines is capable of filtering I/O packets of a particular type from the stream prior to the stream reaching the resource sink virtual machine.
