That's normal. Because of the way simeth is implemented you cannot ping 
the local host IP address from within the simulated kernel.

That's also normal.

The simulated ethernet is using a packet filter and the host interface
is put in promiscuous mode. The filter routes all broadcasts + packet
for the simeth address to the simeth driver, the rest goes to the local
host interface. I believe such configuration forbids sending from the
simeth back to the local host and that's why pinging in any direction does
not work.
