Shouldn't RESTART be semantically the same as SHUTDOWN && CREATE ?!

Just like a system reboot is not exactly the same as powerdown and power
up, restart just WARM RESTARTS the guest - so it essentially just tells
the guest to start over from scratch. So it uses the stored
configuration of the guest, rather than re-reading the guest config
[note that a guest configuration isn't necessarily a file - you can
specify every single component as a command-line argument to the "xm
create" command, so "xm create" actually stores all the values given to
it, and any updates are also changing the stored values]. 

So they are not and can not be exactly the same.

That may well be the case, but it probably takes a bit more digging
before that can be solved.

It actually works. It was my fault.

I tested it by setting cpu_weight in the config and the RESTARTING the 
domain. This did not read the new value but use the last one.
SHUTDOWN and CREATE does recognize the new value in the config file.

Sorry to bother you.
