Abstract
Methods and systems for managing requests for access to devices managed by a hypervisor in virtualized computing environment. A hypervisor receives a request for access to a device from a guest. The hypervisor provides an address hint associated with the device to the guest and an association between the address hint and the device is stored in a reference table. Upon receipt of a subsequent request from the guest including the address hint, the hypervisor performs a look-up in the reference table based on the address hint to identify the device and establishes access to the device by the guest.
