Host: Mandriva Linux 2010, x64, Intel Core 2 Q6600, VBox 3.2.0 + Qemu 0.11.0

Qemu/KVM used as part of Mandriva 2010 distro.
Test between Host <-> Guest: -- Qemu/KVM vs VirtualBox
Connection via VBox "Bridge": (guest has VirtIO, connected to host's eth0)
Connection via VBox "Bridge": (guest has E1000, PRO1000/MT,, connected
to host's eth0)
Connection via KVM "Bridge/TAP": (guest has VirtIO, connected to host's tap0)
+400% speed advantage
Connection via KVM "Bridge/TAP": (guest has E1000, PRO1000/MT,
connected to host's tap0)
+30% speed advantage
I don't know if the performance would be highter with TUN/TAP (VBox
2.0 and older) mode...
i.e. Is the slowdown causes by vboxnetflt or some other reason ?
Unfortunately VBox 3.2.0 does not support TUN/TAP, and VBox 2.0 won't
install on such new hosts.
