1. A computer-implemented method, comprising: allocating a first address translation table in a first portion of a memory in response to detecting a first peripheral component interconnect host bridge; associating the first address translation table with the first peripheral component interconnect host bridge; determining that a first input/output adapter accessible to the first peripheral component interconnect host bridge is configured as a virtualized adapter to provide a plurality of virtual functions to a plurality of logical partitions; in response to determining that the first input/output adapter is configured as the virtualized adapter, assigning a first table manager to manage the first address translation table that is associated with the first peripheral component interconnect host bridge; and configuring the first address translation table for an initial number of virtual functions.
