System and method for trapping system calls for remote execution

A system for executing system calls in a virtualized environment, wherein the system comprises:

• a physical memory device;
• and
• a processor configured to:
• execute a host process corresponding to a guest process executing within a virtual machine and having an associated guest-process virtual address space, the host process having an associated host-process virtual address space;
• map the host-process virtual address space and the guest-process virtual address space to a host physical memory;
• trap a system call invoked by the guest process;
• perform the trapped system call using the host process, wherein state changes in the host-process virtual address space caused by the trapped system call are reflected in the guest-process virtual address space;
• and
• cause execution of the guest process to be resumed after performing the trapped system call.

A non-transitory computer readable medium comprising computer executable instructions, which when executed by a processor, cause the processor to perform operations to execute system calls in a virtualized environment, the operations comprising:

• executing, on a host, a host process corresponding to a guest process executing within a virtual machine and having an associated guest-process virtual address space, the host process having an associated host-process virtual address space;
• mapping the host-process virtual address space and the guest-process virtual address space to a host physical memory;
• trapping a system call invoked by the guest process;
• performing the trapped system call using the host process, wherein state changes in the host-process virtual address space caused by the trapped system call are reflected in the guest-process virtual address space;
• and
• causing execution of the guest process to be resumed after performing the trapped system call.
