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?
