Short answer: don't put any "type" entry.

Long answer:

Using PV device (network and disk) will improve performance, but you
need PV driver (e.g. GPLPV) in domU as well. Withot PV driver, the PV
device will not be used.

Both device (PV and emulated) should be available to domU by default
without any "type" settings. When there's no PV driver, the emulated
one will be used. When there's PV driver on domU, it should be smart
enough to use PV device ignoring (or hiding) the emulated device. So
there's no need to select "type" explicitly.
