Hi Jack,

I found cpucap patch but it doesn't work with 2.6.11 kernel (patched 
with skas). I think
it very interessing if someone merge this patch with UML because it's 
important to limit
cpu cycles for guests instances with simplicity (for a administrator as 
me).  Actually, I have  four UML guests instances and I want to share 
cpu times in %.

For UML mainteners : do you have somes projects tot do this ?

Thanks.
