Abstract: Various embodiments are generally directed to an apparatus, method, and other techniques to handle interrupts directed to secure virtual machines. Work is added to a work queue in a shared memory buffer in accordance with a received request, and a task-priority register is updated to block interrupts not directed toward the secure virtual machine. A timer that expires after a number of cycles of the computer processor have elapsed is started. The secure virtual machine is launched on the computer processor, and a work queue in a shared memory buffer is polled for work to be executed by the secure virtual machine until the work queue is empty or until the timer expires.
