By the way, "PORTTYPE TRUNK" sets the default *virtual* porttype on the 
SET/MODIFY VSWITCH GRANT command.  It has no bearing on the physical port 
type.  Unless a guest needs to access more than one VLAN on the VSWITCH, 
it should be given PORTTYPE ACCESS on the GRANT.

(I regret that we put PORTTYPE on DEFINE VSWITCH.  It was meant to be be 
helpful, but it has caused more problems than it has solved.  Granting 
access to a single VLAN should have resulted in virtual access port; more 
than VLAN, a virtual trunk.  Sigh.)
