Passing communication to or from nested virtual machines can involve one or more mappings. In one example, a host hypervisor can receive, from a physical function of a host computing device, a request generated by a nested virtual function of a nested virtual machine hosted by a guest virtual machine. The request can involve a first guest virtual function of the guest virtual machine, while the nested virtual function can be mapped to a second guest virtual function of the guest virtual machine. The host hypervisor can translate, using a set of mappings stored in a host page table, a guest memory address for the first guest virtual function to a host memory address for the first guest virtual function. The host hypervisor can forward the request to the first guest virtual function using the host memory address determined through translation.
