Thanks, Alan.

To answer your question, I am now able to ping the TCPIP stack address
(after making the change you recommended). I am still unable to ping the
gateway, however.

I suppose I'll go back to beating my head against the wall...

As you suggest below, get rid of the PORTTYPE TRUNK.  Only a guest that
needs access to multiple VLANs on the VSWITCH need be granted PORTTYPE
TRUNK (VLAN-aware).  The others shouldo remain VLAN-unaware (PORTTYPE
ACCESS).  Even VM TCP/IP.

The ony thing that comes to mind is that the IP address/subnet/gateway
on the guests doesn't match what's in the switch.  Can the Linux guest
ping VM TCP/IP?
