A system and method of translation bypass includes a hypervisor retrieving a physical bus address range from a host input-output memory management unit. The hypervisor reserves an allowed address range of the physical bus address range, and sends the allowed address range to a guest virtual machine. Sending the allowed address range sets a guest bus address range mapped by a virtual input-output memory management unit. The guest virtual machine is prevented from accessing any bus address outside of the allowed address range. The hypervisor receives, from the guest virtual machine, an access request to a guest bus address, which is an address within the allowed address range. The hypervisor stores the access request to the guest bus address in physical memory mapped in the host input-output memory management unit to an address outside of the allowed address range.
