What we would like to have, is a checkpointing (& migration) facility  
for long running applications - even for applications where only the  
binaries are available.

Maybe it's not necessary to run a complete virtual machine for each  
slot (and having one execd for the virtual machine and an additonal  
one inside the virtual machine), but to emulate only some layer of a  
virtual machine. The sge_shepherd becomes a sge_virtualizer with a  
tighter integration of the outer and inner world. This would allow,  
also to send e.g. signals from the outer machine to the program  
running in the sge_virtualizer. As VirtualBox is not only open  
source, but also now owned by SUN, maybe there are good options to  
combine it.
