So let me get this straight. GPLPV performance should be somewhere in
the range on Linux HVM with PV drivers, and both of them should be
lower than Linux PV right?

On that opensolaris dom0, Linux PV guest has this performance:
dom0->domU 556 Mbps, domU->dom0 631Mbps
which is lower compared to typical Linux PV on Linux dom0 performance.
Could it be because dom0 <-> domU communication on Opensolaris still
involves physical NIC as the dom0 IP is located on dom0 NIC (which is
different from Linux, where dom0 IP can be on the bridge without
involving any physical NIC)?
I'll try HVM Linux later (takes somewhat longer to setup).
