Abstract
A method and system for transparent secure interception handling is provided. The method and system include deploying a virtual machine (VM) in an environment comprising a hypervisor and a firmware. The method and system include providing buffers in response to deploying the VM, and include executing VM instructions. The method and system include intercepting VM instructions which require access to instruction data and copying the VM state into a shadow VM state. Furthermore, the instruction data is copied to buffers, and the intercepted VM instruction is executed using the buffer. The method and system also include updating the shadow VM state buffer and the VM data in the VM memory using result data in the buffer in response to the executing of the intercepted VM instruction results. Furthermore execution of the VM instructions is resumed based on a state stored in the shadow VM state buffer.
