Yes.

Not applicable since there are no inbound packets from an OSA.

Make sure the Linux guest has configured PRIROUTER in it's network config.
 The other guests are delivering packets to the Linux guest's virtual NIC
that do not have Linux's own IP address in them.  As with a real OSA,
PRIROUTER is required to get the NIC to accept all IP addresses.

Alternatively, change to a layer 2 VSWITCH.  Then all the PRIROUTER stuff
goes away.
