Abstract: Systems, methods, and software described herein facilitate accelerated input and output operations with respect to virtualized environments. In an implementation, a computing system passes a process identifier to a kernel driver for a host environment, wherein the process identifier identifies a guest process spawned in a virtual machine and wherein the kernel driver uses the process identifier to determine an allocation of host memory corresponding to guest memory for the guest process and returns the allocation of host memory. Additionally, the computing system performs a mapping of the allocation of host memory to an allocation of guest memory for the guest element.
