Abstract

Technologies for secure inter-virtual-machine shared memory communication include a computing device with hardware virtualization support. A virtual machine monitor (VMM) authenticates a view switch component of a target virtual machine. The VMM adds configures a secure memory view to access a shared memory segment. The shared memory segment may include memory pages of a source virtual machine or the VMM. The view switch component switches to the secure memory view without generating a virtual machine exit event, using the hardware virtualization support. The view switch component may switch to the secure memory view by modifying an extended page table (EPT) pointer. The target virtual machine accesses the shared memory segment via the secure memory view. The target virtual machine and the source virtual machine may coordinate ownership of memory pages using a secure view control structure stored in the shared memory segment. Other embodiments are described and claimed.
