In one embodiment, a mechanism for out-of-synch virtual machine memory management optimization is disclosed. In one embodiment, a method for out-of-synch virtual machine memory management optimization includes receiving a memory management unit (MMU) synchronization event issued from a VM virtualized by a VM monitor (VMM) of a host server device, and synchronizing one or more unsynchronized page tables (PTs) of a shadow PT hierarchy maintained by the VMM with one or more corresponding guest PTs of a guest PT hierarchy maintained by the VM, wherein the one or more unsynchronized PTs include an unlimited number of unsynchronized PTs in a visible address space of the shadow PT hierarchy that is determined by a current CR3 register address of the shadow PT hierarchy.
