Virtualization exploits virtual rather than actual elements such as computer hardware platforms, storage devices, and computer network resources for example. However, prior art techniques have limitations including, for example, memory requirements and resource requirements which typically either limit their deployment to remote server based systems or limit the number of concurrent virtual machines a system can support. Embodiments of the invention address these limitations by supporting application virtualization on foreign operating systems with reduced resource usage by removing the requirement for virtualization of the entire foreign operating system. The inventive virtualization provides creation of an isolated memory space with isolated code execution using hardware assistance.

Portable application based virtualization

Disclosed are systems and methods for debugging program code using a computing system. The disclosed method includes designating a control point in a software application subject to a debugging procedure, and then executing the program code for the software application as a guest application executing within a virtual machine. Upon detection of a virtualization event, the hardware processor transfers program control to a hypervisor which then determines whether the virtualization event corresponds to the designated control point based on an execution state of the guest application. If so, the virtualization event handler may generate a debugging event that is used by a debugger.

System and method for virtualization-assisted debugging

A method may include establishing a connection between a debugger native to a host operating system and an agent of a virtual machine executing a guest operating system. The host operating system and the guest operating system are of different kernel types. The method may also include receiving, from the agent, information pertaining to the guest operating system. The method may also include performing, using the debugger on the host operating system, non-native system debugging of the guest operating system based on the information pertaining to the guest operating system.
