I'm not sure what you mean.  The way I use it, there is the 'virtual 
machine' and the image.  The image is transportable to any of the 
virtual machine hosts and with only the usual amount of pain to move a 
working system to different hardware, to a physical host.  That's the 
least amount of lock-in I can imagine.  I do wish Centos had better 
hardware-migration tools, though.

OK, but you just said VMware...  I don't use any of the magic stuff that 
a physical machine can't do.  And using the server product I can run 
disk intensive things like databases and NFS home directories on the 
physical host, something that seems to not be recommended under Xen.  
Virtualbox looks like a reasonable option these days too but I haven't 
had a chance to try it out.
