do a cp q vswitch details from tcpmaint. Determine:
 
1. is the linux machine in the list with an ip address?
2. determine the name of the current vswitch controller. From TCPMAINT:
NETSTAT ARP ALL TCPIP <name of current controller>
 
The netstat arp command may need to be issued twice.
 
Does the linux machine show the mac of the OSA along with its IP address?

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?
